The Bad Dog Biter is the sports car of sheet material cutters. It's light. It's compact. Where other cutting tools cut straight lines or curved lines, the Bad Dog Biter cuts drag-race straight and makes track-worth turns with ease.

Powered by your hand drill and a pair of our patented cutting heads. The Bad Dog Biter makes it easy to cut sheet material up to 1/8″ thick. Plus, there are no cords or hoses to get in the way.

Designed to be safe. The head is designed so that your fingers cannot fit into the cutting area.

Like one Bad Dog Biter user said, “These puppies cut circles around other nibblers”.

We couldn’t have put it better.

The Original Biter comes with a 2″ cutting head which is perfect for every-day cutting like trimming flashing, removing rusted sheet metal from a fender, fitting laminate, or cutting sheet plastic. For those cuts that are just out of reach, pop on the Long Dog Head. A full 4″ long, the Long Dog makes access easy to hard-to-reach places such as inside a fender to install marker lights, awkward angles on the dash to install gauges or retrofitting ductwork hidden inside a ceiling. The Long Dog features the same 360° turning radius as the original Bad Dog Biter.

Will, it cut stainless steel? 

Yes, the Biter will cut up to 18 gauge Stainless Steel.

How long does a blade last? 

It will depend on what you cut but figure about 1,000 linear feet for each blade.

How do I get the heads to turn?

It’s as simple as loosening the set screw a half turn using the wrench included in your kit.

How far do the heads turn? 

360° to easily cut any shape!

That’s great but I need a straight cut – what do I do? 

Just tighten the setscrew for arrow-straight cuts.  Because the Bad Dog Biter has two heads, we recommend keeping one cutting head loose and one tight to have both options quickly at hand.

Is it dangerous? 

The head is designed so that your fingers cannot fit into the cutting area.

  5. Jim Grayson

    I love the biter for thin aluminum and plastics. It cuts like magic! I’m very happy I got it but I did have a problem with the bench mounting clamp. The swivel ball broke. I would rather not throw out the whole assembly. Can I get a replacement swivel ball?
