Bad Dog Biter Leash – Get on Track. Stay in Line.
Sure, the Bad Dog Biter cuts like a champ freehand—but when your project demands laser-straight cuts or precise curves, you need a little backup. Enter the Bad Dog Biter Leash—a rugged, easy-to-use cutting guide that turns your Biter into a line-hugging, circle-dominating beast.
The Leash works as both a trim gauge and a circle-cutting jig, giving you full control whether you're ripping straight lines down sheet metal or tracing perfect arcs up to 6 feet in diameter. Just swap in the included threaded head, screw in the Leash, and you’re locked in and ready to roll.
Whether you’re cutting ducts, doing bodywork, or fabricating custom panels, the Leash helps you cut faster, cleaner, and with total repeatability. Made from hardened steel, it won’t flex or shift—even under heavy pressure.

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.
