Great Mazinger's Drill Pressure Punch combines the two most ubiquitous Super Robot weapons, being both a drill and a Rocket Punch.
Tengen Toppa Gurren Lagann. The first chapter even lampshades the male symbolism when one of the girls points out how nasty it would be if Simon "drilled" them. As well as being a choice weapon for the most power mechs, drills are an expanding spiral - a recurring motif in the series which emphasizes advancement in spite of recurrence, thus making them a symbol of the Spiral Power, and the series' theme in general: (Refer also to introductory quote)
Simon: "Mark my words! This drill will open a hole in the universe! And that hole will be a path for those behind us! The dreams of those who've fallen! The hopes of those who'll follow! Those two sets of dreams weave together in a double helix! Drilling a path towards tomorrow! And that's Tengen Toppa! That's Gurren Lagann!! My drill is the drill... that CREATES THE HEAVENS!"
Spoken word for word in Yotsuba&!. But only with a power drill.
In Star Blazers, the Gamilons use a drill missile to penetrate the barrel opening of the Wave Motion Gun and destroy the Argo. It probably would've worked too, if it didn't travel at about 2 miles an hour.
Parodied in Lucky Star. Konata imagines a GunBuster/Getter Robo-esque dentist. And, if Freud Was Right, Miyuki's fear of dentist drills may be symbolic for fearing men in general.... In a later episode, Akira Kogami refers to the page quote... to, rather disturbingly, justify her desire for Ojou Ringlets (or "twin drills", as she calls them). A later episode has her wearing two literal drills in her hair in an attempt to simulate the style.
GaoGaiGar - GaoGaiGar's very legs are formed by the DrillGao, a twin-drilled tank. Super Robot Wars even took the name of the robot's basic melee attack from Guy shouting "Drill Knee". Before the Transformation Sequence, GaiGar can also attach DrillGao to his hands for a devastating punch attack (which also has been used to dig).
GaoFighGar uses DrillGao II, which is enhanced with an expanding, contra-rotating drill setup. Genesic GaoGaiGar has the Straight Drill, used to parry enemy stab attacks, and the Spiral Drill, which is used as a standard attack.

Played realistically in Dai-Guard. When the title robot first uses its drill arm, it gets stuck in the ground and is near-impossible to control due to the torque from the drill. They upgrade to a giant pile driver. When this is damaged in a late-series fight, they have developed the piloting skills to compensate for the torque and use it as a backup. It's even given a Lampshade, when the drill is revealed everyone thinks it's super-cool and can't wait to use it, after it fails so spectacularly they take off their fanboy-goggles and ask "Why the hell did we think that would work?"
Kotetsu Jeeg has the Mach Drill, a pair of rockets Jeeg attaches to his arms so he can fly to his enemy and drill through them. It can also equip the Earth Parts, which give it giant drills for legs (and chainsaws for hands)

Graf Eisen's Raketenform is a drill in all but name. A rocket-powered drill on the end of a hammer, no less. All it lacks are the spiral threads. Amusingly, Graf Eisen shares the (Japanese) voice actor with Simon of Tengen Toppa Gurren Lagann.
Naruto has a fellow by the name of Kimimaro who can control his bones as weapons. In his full Cursed Seal form, he can form a gigantic bone drill over his left arm to attack with.

Neon Genesis Evangelion: Ramiel, the 5th/6th Angel, uses a drill to break into the Geofront. The way Ramiel was in the original, it was not only directly over the Geofront, but over Central Dogma as well - all he needed to do was keep on drilling until the drill came in contact with Lilith - which would of course, cause Third Impact. Rebuild retconns this in a way that makes a tad more sense, having it twist part of itself like a drill in conjunction to using its AT field in a similar manner.
One of Miyu's attack forms in Mai-HiME has a drill-arm.
One of the Omakes in a Fullmetal Alchemist manga volume had Scar waking up in the field hospital with, instead of his brother's arm, a drill attached to his shoulder. Ed added a drill to a baby stroller as part of his attempt to lure Scar and the Homunculi out.

Despite being a giant robot show, drill weapons are thin on the ground in Gundam. Gundam AGE gives us the Gurdolin, a bizarre machine that looks like a plant bulb with arms and a nosecone that projects a sort of beam drill. The MSV model kits for the original Mobile Suit Gundam also featured the strange mobile suit known as the Agg, with drills for arms and buzzsaw-like rock crushers in its shoulders. Makes few appearances in subsequent adaptations, probably because of how ugly it is. One (partial) exception comes in the video game MS Saga: A New Dawn, in which its arms appear as equipable parts.
While not the typical cone drill usually seen in anime, ∀ Gundam features a device used by the Moonrace mobile suits called the Mincing Drill, a cross between a tunnel boring machine and a giant club of the sort used by Onis in Japanese folklore. It was originally designed to be used by worker MS to excavate Lost Technology, but Axe Crazy Corin Nander uses one as a weapon.
Some variants of the YMS-15 Gyan that appear in various video games (including the aforementioned MS Saga as well as Gihren’s Greed) carry a nasty-looking weapon known as the Drill Lance, a Blade on a Stick where the "blade" is a cone drill.

"Let Me Get This Straight: You can invent tanks, (invented 1915) jet-skis, (invented 1973) and a gigantic FRIGGIN' drill, (invented 20XX) but the concept of a hot air balloon (invented 1783) eluuuuuuudes you."
Benny "I'm gonna screw you", the cab driver from the original Total Recall (1990), who is about to use a tunnel drilling machine to crush Douglas Quaid, until Quaid grabs a hand-held drill and cuts into to the operator's cab and does unto Benny before Benny does unto him. And with that accent of Arnie's, we have the immortally classic line:

The machines in The Matrix use gigantic robotic drills, accompanied by swarms of killer robots, to burrow through the earth's crust and attack the underground city Zion. The drills aren't exactly weapons so much as a way into the city; this is zero comfort to those who get in their way.
A bow-mounted drill is a staple feature of the Gotengo (known as Atragon in America), a recurring Cool Ship of Toho features (including Godzilla Final Wars). Making its movie debut in 1963 and based on even older adventure novels, the ship may be Japan's Ur Example and why drills are such a staple in their pop culture.

Transformers: Dark of the Moon introduces The Driller in the form of a titanically large mechanical monstrosity capable of bringing down buildings with ease. They're supposedly Cybertron's apex predators. Shockwave has one as a pet/warbeast, which thus sees plenty of action against Autobots and humans.
In Death Race, you have the heavily armored Dreadnought truck, a mobile hazard equipped with giant drills among its other weaponry. During the race in which it appears, the Dreadnought uses its drill to make a bloody mess of 14K's female navigator, before killing 14K himself.
A non-deadly version in Oceans Thirteen. The protagonists buy a drill, which reportedly dug the Chunnel, and use it to dig under the Bank casino in order to simulate an earthquake as part of their exit strategy. However, the drill ends up being broken just before the job, so they have to buy another one (using Terry Benedict's money).
When Saban contracted the makers of Super Sentai into producing more footage for later seasons of Mighty Morphin', the Plex design office made an updated version of the Daizyuujin / Megazord, which featured the Tyranosaurus' tail as a drill; though the design was rejected in favor of re-using the mecha from Gosei Sentai Dairanger, some fans suspect that the Abaranger/Dino Thunder mecha were influenced by it.
Tensou Sentai Goseiger/Power Rangers Megaforce Season 1 has two examples, as well. First is one of the three Land Brothers, the Sai/Rhinoceros, which has a drill for a horn. The other is during the last third of the season, when the current bad guys take the Biibi bugs/Zombats (this season's version of Make My Monster Grow), and, because they're robots, have them twist themselves into the Biibi Nails/Zombolts, which look like drills in a way. In Goseiger, this may or may not be a subtle reference to the fact that The Dragon for the villains is Yoko, while the 6th ranger is Kamina.
The Mole in Thunderbirds was of the "tunnelling vehicle" variety.
Drills would sometimes be used as weapons in Robot Wars, mostly notable was Sir Killerlot's lance drill.

Also Raveners and their larger, scarier cousins the Trygon, which, being Tyranids, are living drills which burrow up from underneath the enemy and shred their faces.
Standard drills in Mekton are an armour-piercing melee weapon with a low accuracy. Mekton Plus lets you build ones that can be anywhere up to "pinpoint" accurate.
In the MechWarrior Dark Age click-base game, industrial machines can use their civilian equipment as reasonably capable melee weapons. This includes forestry saws, combine harvesters, and of course, mining drills. The MiningMech IndustrialMech uses rock cutters and mining drills as its primary means of attack. Aesthetically subverted, however, in that the drill is not a traditional cone-shaped drill, but more like a trifecta of smaller drills mounted together. With BattleTech caught up to the Dark Age/Age of Destruction clicky game, time wise, canon stats for the Violator Battlemech have been released, making it the first official Battlemech to mount a mining drill as a weapon. It's explained that the mech was actually built for the gladiator games on Solaris VII, where it's popular to mount exotic melee weapons and other Awesome, but Impractical equipment on mechs because crowds like it.
Pokémon has the Horn Drill attack, one of the One-Hit KO moves, and Drill Peck, a powerful Flying-type move. Beedrill, a first-gen Pokémon, has drill-like stingers, hence the name. And Rhydon has a metal drill for a horn that actually spins by itself in Pokémon Stadium.

The boss of the Emerald Hill ZoneSonic the Hedgehog 2 is a car with a drill in front. A fairly simple fight, when it's down to one hit left, it launches the drill at you, in case you weren't paying attention.
Also, the boss of the Mystic Cave Zone in the same game.
Marble Garden Zone in Sonic 3 has three drill-based bosses: The miniboss which excavates the ceiling and causes debris to fall, a flying vehicle driven by Robotnik fought by taking flight with Tails (fighting this boss in "Tails Alone" mode is infamous for its difficulty in some circles), and Knuckles' fight against Egg Robo in a similar drill-equipped flying vehicle, albeit on the ground. Knuckles can, however get to Sonic/Tails' boss by using the spinning tops, enabling you to play with Knuckles and Tails.
One part of Cosmic Wall in Sonic Adventure 2 involves being chased by a giant drill. Knuckles and Rouge can drill into the ground after finding a certain power up too.
The final zone in the first Sonic Advance game reuses bosses from the Genesis game, including Emerald Hill Zone's Drill-car.

Mega Man: In this case, Crash Man's "Crash Bomber" (Mega Man 2), Drill Man's "Drill Bombs" (4), Ground Man's "Spread Drill" (Mega Man & Bass), and Tunnel Rhino's "Tornado Fang" (Mega Man X 3). Ground Man actually has more drills on his body than Drill Man himself! Spark Mandrill even has a drill hand in Maverick Hunter X.
Drill Man and Ground Man get remixed in Mega Man Battle Network. Also — drill squid viruses in the fifth game, and the True Companions are threatened by the misfortune of being in a room right below a giant, out-of-control mining drill (the viruses are found here too, naturally.)
The DrillArm Battle Cards even allow Geo Stelar to utilize the power of drills.
Drills are one of the more unusual classes of weapons in Makai Kingdom — though by no means the most unusual.

Drill Tanks are also available as vehicles, and at least one attack in the game launches drill missiles.
Thrudgelmir has that, plus a third drill on it's head it uses to headbutt with, while KoRyuOh can turn it's hand into a drill before rocket-punching. Both machines actually used to be Grungust MK IIIs.
In Silent Hill: Homecoming, Judge Holloway has a normal power drill with a wood-boring drillbit (wide and flat, with three sharp points — ow) in a cutscene. She is clearly off her rocker and tortures Alex with it while he's restrained to a chair by ramming it into his leg fully in-camera, and the look on Alex's face as he screams is far more effective at unnerving the player than any of the acting in Hostel. In the end, the torture itself inspires a burst of strength on Alex's part sufficient to tear out of his bonds, after which, he promptly shoves the drill up through the bottom of Judge Holloway's jaw. The look on her face at this point is equally brilliant, as are the sound effects. As a final note, the fact that Alex has no signs of hindered movement when the player gains control can be viewed, in addition to the combat system itself, as evidence that his false memories actually give him the skills he would've had if he'd actually been in the military.
Dig Dug. The Mr. Driller series, for that matter. According to the cutscenes in Drill Spirits, the drillers are Dig Dug's kids.
Dordary in Virtual-ON: Oratorio Tangram has a heat-seeking launchable drill for an arm. A few "Vok" variants in the later games also use drills.
In BioShock, the Bouncer-type Big Daddies have their right hands replaced with a drill. As if to prove its effectiveness, the player gets to see a Big Daddy demonstrate its drill on a random splicer. There was blood everywhere. And this is how Dr. Suchong appears to have met his end, after slapping a Little Sister.
In BioShock 2, Subject Delta, a prototype Big Daddy is the player character. The drill you start with is arguably one of the most powerful weapons in the game. When you drill and slam at exactly the same time, you perform a very powerful charge attack that deals massive damage. There's even an upgrade to it which makes it the only weapon you can use. Apparently this is supposed to be a drawback.
Odd PC game Stratosphere, which revolved around floating rocks kitted out as flying battleships, featured the "auger" as a melee weapon. (Well, a ramming weapon, but it worked as long as you were close).
Bulletstorm's final weapon was a powerful gun that fired a spinning drill bit that instantly killed average mooks, flinging them across the room. If they hit a wall, the drill spins with so much force, it tears off the victim's arms, legs, then head. The special attack allows you to kebab multiple enemies.
The arcade (and Dreamcast) game Tech Romancer/Kikaioh, a Fighting Game involving giant robots, has the Combining Mecha Twinzam V.

In Touhou Scarlet Weather Rhapsody, Iku Nagae transforms her scarf into a lightning-imbued drill for some of her specials and spellcards. Tenshi Hinanai also fires rocks that are vaguely drill-like.
Red Faction lets you drive mine drillers. Subverted in that they're actually meant to carve through stone.
Subverted in Worms: Not only is the drill usually relegated to digging as it's pathetically weak, it's a pneumatic drill. Still makes for for an awesome and silly finisher.
X-COM: Terror From The Deep widened the operatives melee arsenal from the previous game (which was limited to the Stun Rod) with a series of oversized power drills. Very efficient at dispatching armored critters, too.

In Fate/stay night and Fate/Zero, Gilgamesh's Wave Motion Sword Ea (the Sword of Rupture) is ostensibly a sword, but designed specifically to resemble a subterranean tunnel drill. When charging up, it sucks in wind by rotating like a drill. The Wave Motion bit comes in when it rips apart spacetime. A less flashy example is Servant Archer's frequent use of a modified duplicate of Caladbolg as a Trick Arrow. His 'Caladbolg II' is dubbed 'the Fake Spiral Sword.'
In Dwarf Fortress, you can wield trap components in adventure mode. Leading to the quote, "I CANNOT HEAR YOU OVER THE SOUND OF ME DRILLING HOLES IN ELVES!". Funnily, it's actually a screw pump.
In Aero Fighters 3, one of Keaton's endings has him wearing nothing but a drill over his crotch.

Attentive players of Monster Hunter will notice that among the hundreds of weapons in the game are a couple of drill lances. No, not blunted practice lances — knight lances, the kind that fits over your arm, about as long as you are tall, and mostly made up of a giant spinning drill bit. There's also the Dragonator: If you need to kill an Elder Dragon fast, this is your weapon of choice, and it's usually mounted to vessels that go out hunting these beasts. Offline, one shows up when fighting the Ceadeus. Online, you get to use it against Jhen Mohran.
The ending for Shadow Lady, a dark, robotic version of Chun-Li, in Marvel vs. Capcom: Clash of Super Heroes featured Jin getting mortally injured in a confrontation with Bison. Shadow (robotic Charlie) and Shadow Lady show up after Bison leaves, and revive him with "cybernation", turning Jin into a dark robotic version of himself... with a drill for an arm.
Same with Metal Fatigue's Drilltruck which is only used to dig tunnels and capture Hedoth structures.
Ditto with the Zuul ships with Rip, Rend, and Radiant Bore sections in Sword of the Stars. These ships look like giant spinning drills in space. However, their only function is "digging" tunnels through node space and cannot be used as a weapon. Even colliding with another ship with the drill results in no more damage than from a normal collision.
The flash-game Epic Battle Fantasy 3, which essentially RUNS on tropes, features several drills, inevitably escorted by Gurren Lagann references. Two of the player characters can learn a special move that summons a huge drill from below the ground, dealing enormous damage to enemies with buffed defense, and one late-game enemy is a Flying Drill-Bot. Seriously, that's its NAME.
In the physics-based flash-game Gravitee Wars, one of the unlockable weapons is a Drill Missile, which will dig all the way through a planet before exploding. Very handy for disposing of one of those annoying enemies who think they can hide on the other side.
Terraria has these available as endgame replacements to the pickaxe. They are also relatively viable as weapons against most enemies that will be encountered while mining.
And its most powerful version, the Hamdrax, consists in a spinning combination of Hammer, Drill and Axe, basically destroying everything and anything it touches in one hit.And dealing huge damage at close range.

There is one in South Park and Cartman will not hesitate to use it against hippies.
The SWAT Kats regularly used drill-bit missiles, and used a Drill Tank, the Turbo Mole, in "Caverns of Horror".
In the old Teenage Mutant Ninja Turtles cartoon, once the Technodrome was moved to the center of the Earth, travel to and from the surface was accomplished via tunneling Transport Modules with big drills on the front.
