Drill America DWC5-530-139 1-1/8" X 1" HSS Annular Cutter with Pilot Pin pneumatic accessory

Annular Cutter 1-1/8" X 1" HSS

The Drill America DWC5-530-139 is a high-speed steel annular cutter designed for fast, efficient hole making with magnetic drill presses. It removes only the material at the hole perimeter to produce a quality hole with less effort. The combination of hardness and toughness provides wear resistance for general purpose metalworking applications. This cutter includes a pilot pin for accurate alignment during operation.

3/4" Weldon Shank Compatibility

Verify that your magnetic drill press accepts a 3/4" Weldon shank before ordering. This cutter is specifically designed for mag drill use only and must not be used with standard hand drills or conventional drill presses. The shank configuration is a critical fitment requirement for safe and effective operation. Check your equipment specifications to confirm compatibility.

Cutting Performance Characteristics

High-speed steel construction delivers a balance of hardness and toughness for reliable wear resistance in normal use. The annular cutting action reduces the material removal volume compared to twist drills, lowering power demand on the magnetic drill press. Heat generation is distributed across the cutting edges during operation. Proper cutting fluid application helps manage temperature and extends tool life.
