    Center Drills

    Create precisely centered holes that mate with lathe centers or drill and countersink in a single step to install fasteners.
    High-Speed Steel
    Image of Product. Front orientation. Center Drills. Center Drills.
    These versatile, wear-resistant center drills cut cleanly in most materials, including plastic, aluminum, and steel.
    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.
    Uncoated—Suitable for most tasks, but won't last as long as coated center drills.

    Tough and wear resistant, these center drills last at least twice as long as high-speed steel. They can also run up to 25% faster at higher temperatures without chipping on hard materials, such as nickel.
    60° Countersink Angle—The most common center drill angle. The short and sturdy tip starts holes that perfectly match lathe centers.
    Uncoated—Suitable for most tasks, but won't last as long as coated center drills.

    Carbide
    Image of Product. Front orientation. Center Drills. Center Drills.
    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.
    Uncoated—Suitable for most tasks, but won't last as long as coated center drills.
    Titanium Carbon Nitride (TiCN) Coated—Resist heat, chipping, and wear, to last up to three times longer than an uncoated option.
    Titanium Aluminum Nitride (TiAlN) Coated—Harder than TiCN, these center drills cut metal as hard as Rockwell C50, such as iron and titanium, without chipping.
    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.

    Center Drill Sets

    Image of Product. Front orientation. Center Drills. Center Drill Sets.
    A variety of sizes to create precisely centered holes that mate with lathe centers or to drill and countersink in a single step to install fasteners.
    High-Speed Steel—These versatile, wear-resistant center drills cut cleanly in most materials, including plastic, aluminum, and steel.
    Carbide—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.
    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.
    Uncoated—Suitable for most tasks, but won't last as long as coated center drills.
    Titanium Carbon Nitride (TiCN) Coated—Resist heat, chipping, and wear, to last up to three times longer than an uncoated option.
    Titanium Aluminum Nitride (TiAlN) Coated—Harder than TiCN, these center drills cut metal as hard as Rockwell C50, such as iron and titanium, without chipping.
    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.

    Short Length

    Round Shank

    Standard

    Harder and more wear resistant than cobalt steel, these carbide bits create an accurate starting place in your workpiece. Cut an indent, then continue drilling with a longer bit. The indent prevents slipping so the final hole is centered and precise. Carbide stays sharp at high temperatures and faster speeds. It 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.
    Short Length—The most rigid bits for drilling the straightest holes.
    Titanium Nitride (TiN) Coated—Drill at higher speeds and last longer than uncoated bits, especially on materials like hardened steel, iron, and stainless steel.
    Titanium Aluminum Nitride (TiAlN) Coated—No drill bits last longer. These are the best for high-speed, high-temperature drilling of very hard and abrasive materials, including titanium and fiberglass.
    Uncoated—Excellent for a range of materials but won't last as long as coated bits.

    Create an accurate starting place in your workpiece. Cut an indent with these bits, then continue drilling with a longer bit. The indent prevents slipping so the final hole is centered and precise. Cobalt steel resists wear to stay sharp when cutting hard materials, such as nickel. Also known as spotting drill bits.
    Short Length—The most rigid bits for drilling the straightest holes.
    Titanium Aluminum Nitride (TiAlN) Coated—The hardest and most wear-resistant coating, especially at high temperatures. These bits are best for hard and abrasive materials, such as iron, titanium, and fiberglass.
