Rotabroach

For perfect holes in sheet metal, pipes and plastic. Cut clean, burr-free holes in seconds. Mini Cutters produce holes by removing a ‘disc’ of metal and have precision ground teeth and flutes to rapidly remove waste material, so they are fast, smooth and highly accurate. Designed to give higher performance and longer cutting life on stainless steel and other difficult materials. Annular cutting action with no ‘dead centre’ area as with a twist drill. It means that less pressure is required to make the hole, so there is less risk of deforming sheet metal. The highly efficient cutting action ensures minimal burring on breakthrough, reducing or completely eliminating the need for additional finishing work. Last up to 300 times longer than hole saws made from M2 High Speed Steel.

Rotabroach Mini Cutters cut clean, burr-free holes in seconds. 

Features and Benefits:
■ Precision ground teeth and flutes ensure a fast, smooth and accurate cut every time.

■ Precision ground M2 high Speed Steel

■ Over 3 times faster than standard twist drills making them highly economical.

■ Low power consumption giving a long life to cordless drills.

Typical Applications:
■ The professional solution for cutting clean accurate holes in sheet metal, pipes and plastics.
