Tungsten Carbide Tipped Hole Cutters
If you need to cut through the toughest materials, these tungsten carbide tipped hole cutters are the perfect solution. Whether it is stainless steel, cast iron, high density resin, or metal plate and sheet metal, these cutters get the job done.
They cut up to 3/16″ deep (4″ bit cuts up to 1″ deep), and have a spring included around the pilot bit to eject the slug. Sizes from 11/16″ to 2″ have a 7/16″ shank, and above that have a 1/2″ shank.
