Drill Mole

Fiction often associates drills with moles, as they, in turn, are associated as Tunnel Kings and miners.

Examples of Drill Mole include:

Anime and Manga

Digmole, Coach Mountain's Medabot in Medabots, is a construction Medabot with drills for hands and on its nose.
Drimogemon from Digimon Adventure, and by extension its Palette Swap NiseDrimogemon.
In Tengen Toppa Gurren Lagann, the heroes use drills to fight and the Team Pet is a mole. Ergo...
GaoGaiGar is a Combining Mecha with a Drill Tank component, resulting in drills on its knees. Its Super Prototype "Genesic GaoGaiGar" is composed of robotic animals rather than vehicles; guess what animals form the legs (and therefore supply its drills)?

Neo-Spacian Grand Mole in Yu-Gi-Oh!. Its fusion form, Elemental Hero Grand Neos, also uses a drill arm.

Monsterpocalypse has the Subterran Uprising which have Monsters and units that are giant mole monsters with drills for weapons, most notably is Drillcon-Vorionnik. Others have buzzsaws or blasters.

Mother 3: Reconstructed Moles. Mecha-Moles! also appear to have one, though, unlike the former, it doesn't use it in battle.
Donkey Kong Country Returns: the moles in World 4 use a Drill Train in a few levels.
Pokémon Black and White: Drillbur and Excadrill, who appropriately learn the moves "Drill Run" and "Horn Drill". The former may be a Shout-Out to the aforementioned Reconstructed Moles from MOTHER 3.
- The latter may also be a shout out to Tengen Toppa Gurren Lagann.
Though it's combined with a ... duckbill ... for some reason, Duckbill Mole (Platypus, perhaps?) from Mega Man X Command Mission is a drill fanatic.
The Drillbot Badniks from the Sonic the Hedgehog series.
MARDEK has Drillions, which supposedly use their drill snouts to mine for gems to eat. And also to hurt Mardek.
Super Mario Galaxy's Major Burrows digs into the ground by spinning at high speeds using his spiked helmet.

Dutch cartoon series Boes, about an Ox who runs a farm, (roll with it) features as his main antagonist plague a crowd of moles that look just like the trope picture on the left.
Digger from Lilo & Stitch: The Series, who is a brown alien with a drill for a tail.
