2-3/8 in. Carbide Annular Cutter

The HOUGEN 3-18276 Copperhead annular cutter is a pneumatic accessory designed for magnetic-base drills. It creates 2-3/8 inch diameter holes with a 3 inch depth of cut in structural steel and plate. The carbide tips provide wear resistance for professional metal fabrication and maintenance tasks.

Installation and Common Issues

The cutter mounts directly into a compatible magnetic drill arbor using the standard shank. Ensure the pilot pin is correctly seated to eject the slug after cutting. Common issues include premature tip wear from insufficient coolant or excessive feed pressure, and cutter breakage if the workpiece moves during the cut.

Pre-Order Compatibility Checks

Verify your magnetic drill accepts the cutter shank diameter and has sufficient stroke for the 3 inch cutting depth. Confirm the machine delivers the low RPM and high torque required for large-diameter carbide tooling. Check that your coolant delivery system can reach the cutting zone effectively. California Proposition 65 warning applies to this product.
