    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 and tap a variety of hole sizes. These taps and drill bits are for use on metal and plastic.
    Uncoated High-Speed Steel Tap—Uncoated high-speed steel taps have a longer tool life than carbon steel. They are strong enough for most jobs but don’t last as long as other high-speed steel taps. Use them for small-scale jobs.
    Uncoated Cobalt Steel Tap—Uncoated cobalt steel taps have higher strength and wear resistance than carbon steel and high-speed steel taps.
    Black-Oxide High-Speed Steel Tap—Black-oxide high-speed steel taps have a longer tool life than carbon steel. They cut with less friction than uncoated taps.
    Titanium Nitride (TiN)-Coated High-Speed Steel Tap—Titanium nitride (TiN)-coated high-speed steel taps have a longer tool life than carbon steel. They resist heat and wear better than uncoated taps, letting them last up to twice as long.
    Plug Chamfer—Plug-chamfer taps are a versatile choice for most tapping applications. With 3-5 chamfered cutting threads, they require moderate torque and are often used for start-to-finish tapping of through holes and closed-end holes. However, they do not start threads as easily as taper chamfers. When using them to tap closed-end holes, be sure to leave sufficient space at the bottom for chips to accumulate.
    Black-Oxide High-Speed Steel Drill Bit—Black-oxide high-speed steel drill bits have a longer tool life than carbon steel. They cut with less friction than uncoated drill bits.
    Black/Gold Oxide High-Speed Steel Drill Bit—Black/Gold-oxide high-speed steel drill bits have a longer tool life than carbon steel.
    Titanium Nitride (TiN)-Coated High-Speed Steel Drill Bit—Titanium nitride (TiN)-coated high-speed steel drill bits have a longer tool life than carbon steel. They last longer and can drill at higher speeds than uncoated and oxide-coated drill bits.
    Uncoated Cobalt Steel Drill Bit—Uncoated cobalt steel drill bits have higher strength and wear resistance than carbon steel and high-speed steel drill bits.
    Uncoated High-Speed Steel Drill Bit—Uncoated high-speed steel drill bits have a longer tool life than carbon steel. They are strong enough for most jobs but don’t last as long as other high-speed steel drill bits. Use them for small-scale jobs.

    Drill Taps

    Spiral Flute

    Drill holes and cut threads without switching tools. Made of high-speed steel, these taps are for use on most metal and plastic. The square shank is compatible with 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.
    Spiral Flute—Taps with spiral flutes keep chips clear by drawing them back toward the tap and out of the hole.

    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.
