    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.

    Double-Chamfering

    Cut Style

    Made of carbide-tipped high-speed steel, these end mills provide a sharper, harder edge at high temperatures than plain high-speed steel. Because they aren’t as brittle as solid carbide, they can be used in less rigid setups, such as manual milling machines. The teeth are angled in two directions so you can make top and bottom chamfers without having to flip the workpiece.
    Uncoated—Use uncoated end mills for general purpose milling and short production runs. They stay sharper than coated end mills when used on soft materials like aluminum, leaving a better finish.
    Titanium Nitride (TiN) Coated—Titanium nitride (TiN)-coated end mills create less friction than uncoated end mills, which means they last longer when run at similar speeds. Use coated end mills for demanding, high-speed jobs in hard material as well as for longer production runs. The coating reduces friction and vibration as they’re used, making them more wear resistant than uncoated end mills.
    Titanium Carbon Nitride (TiCN) Coated—Titanium carbon nitride (TiCN)-coated end mills have a hard, smooth finish that resists chipping and wear and prevents material from accumulating on the cutting edge. They’re especially good for use in aluminum. Use coated end mills for demanding, high-speed jobs in hard material as well as for longer production runs. The coating reduces friction and vibration as they’re used, making them more wear resistant than uncoated end mills.
    Aluminum Titanium Nitride (AlTiN) Coated—Aluminum titanium nitride (AlTiN)-coated end mills dissipate heat better than other end mills, especially at high speeds. At high temperatures, the coating creates a layer of aluminum oxide that transfers heat to the chips, keeping the tool cool, even when used without lubrication. Use coated end mills for demanding, high-speed jobs in hard material as well as for longer production runs. The coating reduces friction and vibration as they’re used, making them more wear resistant than uncoated end mills.
