    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.

    Tap and Drill Bit Sets

    Metal Case

    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.
    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.
    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.

    and Through-Hole Tap

    Quickly restore stripped threads—these inserts come with through-hole taps and installation tools. The tough coils on these inserts expand once installed to anchor in a tapped hole.
    Pronged—The prong attaches to an installation tool for precise control as you drive inserts in. Remove the prong with a punch or break-off tool before inserting a screw.
    18-8 Stainless Steel—The choice for wet and outdoor environments, these inserts resist rust and mild chemicals.
