Ditch the snips. Skip the grinder. With the Bad Dog Biter, you can turn any standard drill into a high-performance sheet metal nibbler built for tight turns, custom cutouts, and clean lines—all without distortion, fatigue, or wasted material.
Engineered with a patented steerable cutting head, the Biter lets you guide each cut from your fingertips. Whether you're tracing a tight-radius curve, making a panel cutout, or cutting ductwork overhead, this tool glides through aluminum, steel, plastics, and more with ease.
Need to cut non-metal materials? No problem. The Biter handles Lexan, Formica, plastic, leather, paper, and even thin wood veneers like a champ. The dual-head design doubles blade life, and the pass-through blade system lets you swap blades in seconds—just loosen one set screw.

Sure Does! Our hex end allows you to snap it into your impact gun or you can use it on any battery-operated/corded drill.
As safe as it gets! We created a biting head that will chew through materials… not your finger! The blade is recessed in the cutting head and the opening is only wide enough to let in the thickness of materials the tools can cut.
With most materials it helps with cutting speed, but isn't required. On soft materials like Aluminum and Brass it is required or the metal will gum up the mechanism.
The mechanism of the Bad Dog Biter is Guaranteed for Life! If it ever fails we will repair or replace it. The Pins and Heads are consumables. You get an extra blade and cutting head in your kit which should be good for about 2000 feet of cutting 18 gage mild steel. When you wear them out they are easy and inexpensive to replace.
Dull or damage our tools and we will repair or replace them.
