Evolution Power Tools CC137 1-3/8" Annular HSS Cutter

1-3/8" Annular HSS Cutter for Magnetic Drills

The Evolution Power Tools CC137 is a high-speed steel annular cutter with a 1-3/8 inch diameter and one inch cutting depth. It is designed for use with magnetic drilling machines in metal fabrication and maintenance work. The cutter removes only the hole periphery to produce a finished, burr-free hole. This accessory suits trade professionals who need fast, accurate holes in structural steel.

Sustained Cutting Behaviour in Steel

Because the cutter engages only the hole perimeter, it requires less feed force and generates less heat than a twist drill of the same diameter. The high-speed steel body maintains hardness during prolonged cuts in mild and structural steel. Chip evacuation remains consistent through the annular geometry, reducing the risk of binding during deep passes. Operators can maintain steady progress without frequent tool withdrawal.

Replaces Twist Drills for Large-Diameter Holes

This cutter replaces twist drills and hole saws when producing holes of this diameter in plate or beam. The jump is worth it when hole quality, speed, or reduced machine load are priorities. It is not suited for non-ferrous materials, wood, or handheld drilling without a magnetic base. Buyers needing smaller diameters or different cutting depths should select an alternative cutter from the range.
