Fein ST Series Carbide Tipped Annular Cutters
The Fein ST Series Annular Cutters offer carbide tipped edges for extended tool life. They are designed for cutting steel plate, stainless steel, cast iron and aluminum. Annular cutters are hollow drill bits that cut only the periphery of a hole, reducing the torque and horsepower requirements for many drilling applications. They remove less material than standard twist drill bits, have faster cutting speeds, and are more efficient than twist drills or metal hole saws.
