Description
Overview:
The Timco Cone Cutter 16-31mm is a high-speed steel (HSS) step tool for creating and enlarging holes in thin sheet metal up to 2mm thick. It drills progressively through a series of diameters, so one cutter covers multiple hole sizes while also de-burring as it advances. Built from durable HSS for a long service life, it is suitable for use with standard corded or cordless drills and drill presses fitted with a 3‐jaw chuck. Ideal for site work and workshop use, it helps produce clean, round holes without grabbing in light-gauge materials. Manufacturer Part Number: CC1631. Use with an appropriate cutting lubricant to control heat and extend tool life.
