    Our basic drill bits are also the most versatile. Cut holes in a variety of metals, from the softest aluminum to the hardest steel.
    Extended Length—Drill through panels and thick workpieces with our longest bits. Their length is good for creating deep holes but makes them less rigid than other bits. As a result, they are more prone to wobbling or breaking, especially when drilling hard materials.
    Black Oxide—The dark finish increases wear resistance and reduces friction to improve chip flow, so these bits can last 50% longer than uncoated bits.
    Uncoated—The most economical option, uncoated bits perform best when used on low-carbon steel and aluminum. Polished to reduce friction, they're also known as bright finish bits.

    Wear and heat resistant, these stay sharp longer than precise-cut bits made of plain steel. The sharp center point keeps the bit from wandering during drilling to cut accurate straight and overlapping holes, even across the grain. Also known as brad-point bits.

    With better heat and wear resistance than high-speed steel, these cobalt steel end mills can run at higher speeds and provide better performance on hard material, such as iron and steel. Also known as taper degree end mills, they're often used to machine angled slots in dies and molds.
    Uncoated Cobalt Steel—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 Cobalt Steel—Use titanium nitride (TiN)-coated end mills for demanding, high-speed jobs in hard material as well as for longer production runs. They create less friction than uncoated end mills, which means they last longer when run at similar speeds.
    3 Flutes—End mills with three flutes provide better chip clearance for high-volume, high-speed plunge, slotting, and roughing cuts.
    Center Cutting—Center-cutting end mills allow plunge cuts into a surface.
