Jack Hammer, or Drill Bit, is a male background pony who appears both as a Pegasus and as an Earth pony. He has a light brown coat, two-toned dark gray mane and tail, blue eyes, and a cutie mark usually of a screwdriver and two screws and rarely of a police shield. He is unnamed in the show, but he is named "Jack Hammer" with a trademark symbol and "Drill Bit" in different versions of merchandise. He has a speaking role in The Mysterious Mare Do Well.
Jack Hammer's color scheme resembles those of Filthy Rich and Cherry Fizzy. His beard stubble is rarely not present, similarly to the beard stubble usually of "Rivet" and the mustache rarely of Lucky Clover.
Depiction in the seriesJack Hammer first appears as a stubbly Pegasus pony in the season one episode Sonic Rainboom. He is among several Cloudsdale construction workers who admires Rarity's wings when she passes by.
In the season two episode The Mysterious Mare Do Well, he appears once again as a construction worker, this time as an Earth pony, and has his first spoken line when he is rescued by Mare Do Well.
In the season five episode Made in Manehattan, Jack Hammer appears once again as a clean-shaven police officer.
In the season seven episode Fluttershy Leans In, Jack Hammer appears in his Earth pony form as a construction worker working on Fluttershy's animal sanctuary. In Honest Apple, he appears as an Earth pony construction worker again building the contest runway outside Carousel Boutique.
MerchandiseIn Enterplay's collectible card game, a Gen Con Indy 2013 demo card of him lists his name as "Jack Hammer" with a trademark symbol, cards α #30 C and α #ƒ16 of him list his name as "Drill Bit", and all three cards of him feature him as a Pegasus with beard stubble and list his quote, "Some ponies ask me why I use power tools on clouds. I tell 'em, because I can." Card α #139 U, Hard Hat, shows Jack Hammer as an Earth pony with beard stubble. In the game's expansion set Canterlot Nights, card #38 C of Steam Roller attributes to Drill Bit the quote, "I saw a whole building collapse on him once and he walked away from it. I mean, the building was made out of clouds, but it was still pretty impressive."
