    Tough and wear resistant, cobalt steel bits last at least twice as long as high-speed steel. They can also run up to 25% faster at higher temperatures without being damaged on hard materials, such as nickel.
    Short Length—The most rigid bits for drilling the straightest holes.
    Titanium Nitride (TiN) Coated—Drill at higher speeds and last longer than uncoated and oxide-coated bits, especially on tough materials like hardened steel and nickel.

    The hardest and most wear-resistant bits, the flutes clear chips and improve coolant flow. They prevent clogs and dissipate heat that can damage the bit and the hole. 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 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.
    Jobbers' Length—These bits have the balance of rigidity and length needed for most applications.
    Titanium Nitride (TiN) Coated—Drill at higher speeds and last longer than uncoated bits, especially on materials like hardened steel, iron, and stainless steel.
    Uncoated—Excellent for a range of materials but won't last as long as coated bits.

    Pipe and Conduit Drill Taps

    Image of Product. Front orientation. Drill Taps. Pipe and Conduit Drill Taps.
    Drill and thread holes for pipe and conduit without switching tools. Made of uncoated high-speed steel, these tools are for use on most metal and plastic. Their right-hand spiral flutes keep chips clear by drawing them back toward the tap and out of the hole. With a square shank, they're compatible with tap wrenches and tap holders for drill presses and milling machines. All have a plug chamfer with 3-5 chamfered cutting threads, so they're suitable for start-to-finish tapping of through holes.

    High-Speed Steel Square End Mills

    Use these end mills for general purpose milling in most material, such as aluminum, brass, bronze, iron, and steel. They have a square end for milling square slots, pockets, and edges.
    End mills with fewer flutes provide better chip clearance for high-volume, high-speed plunge, slotting, and roughing cuts; end mills with more flutes provide a finer finish and operate with less vibration when run at high speeds.
    Uncoated High-Speed Steel—Use uncoated end mills for general purpose milling and short production runs.
    Titanium Nitride (TiN)-Coated High-Speed Steel—Use titanium nitride (TiN)-coated end mills for demanding, high-speed jobs in hard material as well as for longer production runs. They’re more wear resistant than uncoated end mills, which means they last longer when run at similar speeds.
    Center Cutting—Center-cutting end mills allow plunge cuts into a surface.
