Copperhead Carbide Tip Annular Cutters feature a durable grade carbide insert for extended tool life when used with Hougen Mag Drills on abrasive and tough-to-cut materials. The unique Hougen design also includes a special tool geometry that helps maintain better chip flow than other brands.
Using the set screw arbor system can result in up to 2x the tool life as tool-less systems. Copperhead cutters are available with two different shanks.
