Hole Cutters – Heavy Duty

High Speed Steel

List No. HC690 – Pilot drill furnished with each cutter
HOLE MAKING tubing, steel plate, or any other larger diameter shallow hole cutting. A versatile and highly useful tool!
These Hole Cutters are recommended for use in hand held air or electric
drill motors as well as light drill press applications in sheet metal, thin wall

This tool centers quickly and is held securely in position after the pilot
drill has entered the work piece. The cutter body then cuts a clean,
burr-free hole faster than conventional twist drills or hole saws.
With normal care, tool life is significantly longer than other hole cutting
tools. Inexpensive resharpening will allow repeated use.
