Evolution Power Tools CC437L 7/16" Annular HSS Cutter

7/16" Annular HSS Cutter

The Evolution Power Tools CC437L is a 7/16 inch diameter annular cutter made from high-speed steel. It is designed for use with magnetic drills to produce clean holes in metal. The cutter creates a reamed, burr-free finish by removing only the perimeter material. It suits fabricators and maintenance teams needing accurate holemaking.

2-inch depth capacity and cutting efficiency

This cutter handles material up to 2 inches thick in a single pass. Because it cuts only the hole periphery, it requires less power and time than a twist drill of the same diameter. The high-speed steel construction provides wear resistance for mild and structural steel. It runs out when the material exceeds the cutting depth or hardness rating.

Upgrade from twist drills for magnetic drilling

The annular design replaces standard twist drills on magnetic drill presses where speed and finish quality matter. The jump is worth it when producing multiple holes in plate or beam, as each cut yields a finished hole without secondary reaming. It is not suited for handheld drilling or non-magnetic drill setups.
