Cut large holes with drill presses and portable drills that have a standard-size chuck. The shank on these bits has a smaller diameter than the cutting tip. High-speed steel is good for general purpose drilling in most metals. Also known as Silver and Deming bits.

One cobalt bit drills multiple hole sizes and lasts twice as long as high-speed steel. They have steps with progressively larger diameters—the deeper they drill, the bigger the hole. Count the steps as you drill to achieve the proper size. These bits also deburr as they cut, so they're good for thin materials like sheet metal and plastic panels. Wear and heat resistant, high-speed steel is versatile for use on a range of materials.

Our basic drill bits are also the most versatile. Cut holes in a variety of metals, from the softest aluminum to the hardest steel.

Tough and wear resistant, cobalt steel bits last at least twice as long as high-speed steel. They can also run up to 25% faster at higher temperatures without being damaged on hard materials, such as nickel.

Our hardest reduced-shank bits, these stay sharp at high temperatures and faster speeds. The shank is smaller than the cutting tip to make large holes with drill presses and portable drills that have a standard-size chuck. They offer the best performance on hard and abrasive materials, such as titanium. Also known as Silver and Deming bits.

Make rough holes in wood for jobs such as running wire and pipe through framing studs and sheets. These bits have two sharp edges for faster cuts than fluted bits and won't cause the surface of the material to splinter. A centering point keeps them stable while drilling soft and hard woods such as pine, plywood, and oak. Also known as spade bits.

Multiple teeth cut away large amounts of material to bore clean, flat-bottom holes in wood. The center guide point keeps the bit stable and centered for drilling straight, angled, and overlapping holes, like those used create joints. Also known as Forstner bits.
