    Even on hard and difficult-to-machine materials, these bits cut holes so precise that you don’t need to finish them with a reamer. The double-edged flutes keep these bits centered to drill straighter and smoother than other types. Carbide bits are the hardest and most wear-resistant to stay sharp at high temperatures and faster speeds. Also known as double-margin drill bits.
    Jobbers' Length—These bits have the balance of rigidity and length needed for most applications.
    Aluminum Titanium Nitride (AlTiN) Coated—The hardest and most wear-resistant coating, especially at high temperatures. These bits are best for hard and abrasive materials, such as iron and titanium.

    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.

    The hardest and most wear-resistant center drills you can buy. They 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 use a rigid machine tool holder to prevent breakage.
    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.
    Aluminum Titanium Nitride (AlTiN) Coated—The hardest and most wear-resistant coating we offer, these center drills cut through metals as hard as Rockwell C70 without losing their sharp cutting edges.
