About Drill Bits

Make fast bit changes—each bit has the same shank diameter, eliminating the need for different collets to hold each size. Harder than high-speed steel, cobalt steel, and carbide-tipped bits, these maintain their sharp edges longer. These bits require rigid toolholding to prevent breakage and should not be used in hand-held drilling applications. All are jobbers’ length so they have the rigidity and length required for most applications. A four-facet point keeps the bit centered without a pilot hole.

Hex-Shank Drill Bit Sets

Insert these bits directly into power screwdrivers, impact drivers, and other tools that accept 1/4" hex shanks. They are titanium nitride (TiN) coated for wear and temperature resistance.

Bit Assortments

These assortments contain general-purpose bits.

Hex shank bits (also known as insert bits) are used in hand drivers or with a bit adapter in power tools.

Hex shank bits for power tools have a groove in the shank and fit directly into power tools without an adapter. They offer more reach for recessed holes and less wobble compared to a hex shank bit used with an adapter.

Tap and Drill Bit Sets

Set with Plastic Pouch

Drill and tap a variety of hole sizes. These taps and drill bits are for use on metal and plastic.

High-speed steel taps and drill bits have a longer tool life than carbon steel. Uncoated high-speed steel taps and drill bits are strong enough for most jobs but don’t last as long as other high-speed steel taps and drill bits. Use them for small-scale jobs.

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.
