Features and benefits

Rotabroach Master Kits contain 16 different sizes of Rotabroach Sheet Metal Hole Cutters. The kit adds many 32nd and 64th sizes which were previously not available. Included in the kits are an arbor, extra pilots and center punch in a plastic storage case.

Rotabroach Cutters are for use in handheld drills or drill presses. They make holes 3x faster and last 10x longer than twist drills or hole saws.

Rotabroach Cutters cut the material rather than ripping and tearing through, as conventional tools do. There is no deforming of the surface and they leave a clean burr-free hole.

These tools are designed for sheet metal, plate and plastic materials up to 1/4” thick. Rotabroach cutters are used in all areas of the automotive industry from manufacturing, general metal fabrication, collision, racing, specialty/aftermarket installation and automotive restoration.


The precise cutting angles on the teeth of the Rotabroach Cutter allows for faster holemaking and longer tool life. Because users are cutting the outside ring and not turning the entire hole into chips, they need less horsepower to make the hole. The result is users can drill the hole faster and with longer tool life, saving time and money.

Because of the high-quality of the hole which is made, users do not have a secondary operation of grinding down the burr on the backside of the hole.


Rotabroach Cutters are made from M2 high speed steel and precision ground and harden to very tight tolerances. The products are proudly made in the USA.
