Precision annular cutter for magnetic drilling

The HOUGEN 18222 Copperhead carbide annular cutter cuts 11/16 in holes through steel plate up to 6 in deep. It is built for fabricators, structural steel erectors and maintenance crews who use magnetic-base drills on job sites or in shops. The carbide tips resist heat and wear during prolonged cuts in tough alloys.

Suited for deep-hole work in ferrous metals

Teams needing fast, accurate through-holes in beam, plate or pipe will benefit from the cutter geometry. Buyers who only drill shallow holes in thin sheet, or who require non-ferrous or composite cutting, should look at alternative tooling designed for those materials.

Check drill compatibility and safety data

Verify that your magnetic drill accepts the cutter shank and can deliver the required stroke length for a 6 in depth of cut. Review the California Proposition 65 notice supplied with the product and follow all recommended personal-protection and ventilation practices.

Questions about this item

What magnetic drill arbor is needed for the 11/16 in Copperhead cutter?

The cutter fits a standard 3/4 in Weldon shank, so a magnetic drill with that arbor will accept it directly.

Can the 11/16 in annular cutter run on a lower-RPM magnetic base drill?

Yes — carbide tips tolerate the slower speeds of older magnetic drills, though feed pressure should be reduced to avoid chipping.

How do I confirm the 11/16 in hole is being cut cleanly?

A steady stream of long, curled chips and a smooth, burr-free bore indicate the cutter is advancing at the correct feed rate.
