Carbide Tip Safe Drill Bits

These premium quality drill bits have an extra thick carbide tip to penetrate hardened and case hardened steel over 45Rc/421Hb. The longer carbide tip allows it to be resharpened if it gets dull. The point of the bit has a negative rake angle to reduce chipping and help disperse the heat from the cutting edge.
These heavy-duty bits have high speed steel bodies and a straight flute for strength and clean chip removal.
