    Carbide Drill Bit Sets

    The hardest and most wear-resistant drill bits you can buy. Carbide bits stay sharp at high temperatures and faster speeds for the best performance on hard and difficult-to-machine materials. They last 10 to 20 times longer than their closest alternative, cobalt steel. Carbide can be brittle, however, so these bits require a rigid machine tool holder to prevent breakage and should not be used in hand drilling applications.

    These bits have the balance of rigidity and length needed for most applications.
    Titanium Carbon Nitride (TiCN) Coated—The hard, smooth finish prevents chipping and wear and reduces friction to keep material from building up.

    60° Countersink Angle—The most common center drill angle. The short and sturdy tip starts holes that perfectly match lathe centers.
    82° Countersink Angle—Start a hole with cone-shaped recesses so inch screws sit flush with the surface.
    90° Countersink Angle—Start a hole with cone-shaped recesses so metric screws sit flush with the surface.
    Titanium Carbon Nitride (TiCN) Coated—Resist heat, chipping, and wear, to last up to three times longer than an uncoated option.
