    Chip-Clearing Tap and Drill Bit Sets for Through Holes

    Image of Product. Front orientation. Tap and Drill Bit Sets. Chip-Clearing Tap and Drill Bit Sets for Through Holes.
    Also known as gun taps, the taps in these sets have spiral-point flutes that push chips ahead of the tap and out of through holes. Because they don't need to be reversed to prevent buildup, they produce threads more efficiently than standard taps and are suitable for production work. Taps have a square shank for compatibility with tap wrenches and tap holders for drill presses and milling machines. With a plug chamfer, they have 3-5 chamfered cutting threads, so they're suitable for start-to-finish tapping. All taps and drill bits are made of high-speed steel for use on most metal and plastic.

    Drill/Mill Cut

    Style

    Made of cobalt steel, these end mills have good heat and wear resistance, so they can run at high speeds in hard material. A 90° pointed tip allows them to be used for drilling as well as for slotting, profiling, and chamfering cuts. All are center cutting, allowing plunge cuts into a surface.
    Uncoated Cobalt Steel—Use uncoated end mills for general purpose milling and short production runs.
    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’re more wear resistant than uncoated end mills, which means they last longer when run at similar speeds.
