    Helical Insert Taps

    Image of Product. Front orientation. Taps. Helical Insert Taps.
    Match the size of helical inserts so they fit tightly when installed in the hole.
    High-Speed Steel—These taps resist heat and wear to stay sharp.
    Plug Chamfer—Our go-to chamfer type. With a longer taper than a bottoming chamfer, they are easier to turn but won't thread as close the bottom of a hole.
    Bottoming Chamfer—Cut all the way to the bottom of blind holes with taps that have the shortest taper. Since these require the most force to turn, they’re often used to finish holes started by taper- or plug-chamfer taps.

    These tools come with one high-speed steel insert for use on steel and stainless steel and one high-speed steel insert for use on softer materials, such as aluminum and brass. When one point of an insert dulls, rotate it to use a sharp point. When all points dull, replace the insert rather than the whole tool.
    3/8" Wide Shank—Tool with 3/8" shank can cut external right-hand threads.
    1/2" Wide Shank—Tool with 1/2" shank can cut external right-hand threads with one end and internal right-hand threads with the other.
    3/4" Wide Shank—Tool with 3/4" shank can cut external right- or left-hand threads. To cut right-hand threads install an insert in the pocket on the left side of the tool. To cut left-hand threads install an insert in the pocket on the right side of the tool.

    Left-Hand Thread Helical Insert Taps

    Image of Product. Front orientation. Taps. Left-Hand Thread Helical Insert Taps.
    Size holes for installing helical inserts that anchor left-hand bolts and rods. Helical inserts reinforce the connection between holes and fasteners that secure counter-clockwise rotating parts. Left-hand threads keep components such as flywheels and propellers from loosening and spinning off.
    High-Speed Steel—These taps resist heat and wear to stay sharp.
    Plug Chamfer—Our go-to chamfer type. With a longer taper than a bottoming chamfer, they are easier to turn but won't thread as close the bottom of a hole.

    Flat-Surface Cut Style

    With larger diameters than end mills, these cutters remove greater amounts of material to create a smooth, flat channel in the face of a plate, bar, or other wide workpiece. Compared to fly cutters, they’re more rigid, which makes for a better finish. Also known as shell cutters. Cutters with fewer teeth provide better chip clearance for high-volume, high-speed cuts. Those with more teeth provide a finer finish and generate less vibration at high speeds.
    Uncoated—Use uncoated cutters for general purpose milling and short production runs. They stay sharper than coated cutters when used on soft materials like aluminum.
    Titanium Nitride (TiN) Coated—Titanium-nitride (TiN) coated cutters create less friction than uncoated cutters, which means they last longer when run at similar speeds. Use coated cutters 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 cutters.
    Aluminum Titanium Nitride (AlTiN) Coated—Aluminum-titanium-nitride (AlTiN) coated cutters dissipate heat better than other cutters, 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 cutters 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 cutters.
    High-Speed Steel—High-speed steel cutters are good for general purpose milling in most materials including aluminum brass, bronze, and steel.

    Tri-Groove Bit Sets

    Image of Product. Front orientation. Screwdriver Bits. Tri-Groove Bit Sets.
    The bits in these sets turn tri-groove screws. They're commonly used to fasten signs, lighting fixtures, and other types of public property.
    Quick-Change Hex Shank—Lock these bits directly into power tools. They won't wobble as much as bits paired with an adapter, so they are the best choice for high-precision tasks.
    High-Speed Steel—Harder and more heat resistant than plain steel. These bits withstand the intense friction of high-speed power tools without deforming or softening.
