    High-Speed Steel Step Drill Bits

    Image of Specification. Standard. Front orientation. Contains Border. Standard Point. For Metal.

    Standard

    Drill multiple hole sizes using only one bit. These 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.
    Black Oxide—The dark finish increases wear resistance and reduces friction to improve chip flow, so these bits can last 50% longer than uncoated bits.
    Uncoated—The most economical option, uncoated bits perform best when used on low-carbon steel and aluminum. Polished to reduce friction, they're also known as bright finish bits.

    More wear resistant than high-speed steel, these bits cut large holes with tools that have a standard-size chuck. The shank has a smaller diameter than the cutting tip and fits drill presses and portable drills. 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. Also known as Silver and Deming bits.

    Carbide-Tipped Drill Bits for Masonry and Concrete

    Crush rather than cut material so bits don’t jam or overheat while drilling masonry and concrete. The ultra-hard carbide tip breaks masonry into pieces and the widely spaced flutes channel them out of the hole. These bits stay sharp, resisting wear and heat that will dull or break other bits.

    Rebar-Cutting Carbide-Tipped Drill Bits

    No need to move the hole when you encounter rebar in concrete—swap out your masonry bit for one of these cutters. They have a carbide tip that resists wear to stay sharp. Once you're through the rebar, resume drilling with the masonry bit.

    Drill Bits for Wood

    Image of Product. Front orientation. Drill Bits. Drill Bits for Wood.
    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.

    Chip-Clearing Drill Bits for Wood

    Prevent clogs that wear the bit and slow down drilling. The flutes on these bits have an open design that pulls chips out of the hole faster than standard spiral flutes. Also known as pole or ship auger bits, they are used to cut deep holes through lumber, railroad ties, and utility poles.

    Not only do these bits bore holes faster than standard smooth-finish bits, they create less friction and heat buildup to last longer. The spurred teeth have a long life, but they're less effective at guiding the bit so cuts on angled and overlapping holes tend to be rougher. Also known as multispur bits.

    Carbide-Tipped Steel

    Carbide tipped to stay sharp longer than tool steel bits, these are better on tough and abrasive materials, such as plywood and hardwoods. They have multiple teeth that 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.

    Inserts for Carbide-Insert Drill Bits

    Pair an inner and outer insert with a compatible drill bit body (sold separately) to drill a large number of holes with high precision. When the cutting edges dull, replace the carbide inserts instead of the entire bit.
    Inserts sold individually come packed in a clear plastic case to protect cutting edges during shipment. Inserts sold in packs come factory sealed from the manufacturer for maximum traceability.

    Shown with Carbide Inserts

    (Sold Separately)

    When you need to drill dozens or even hundreds of holes, use a bit with replaceable carbide inserts. Once the cutting edges wear down, just change the inserts instead of sharpening or throwing the bit away. The holes in the bit channel coolant through the tool for more efficient chip evacuation. Also known as indexable drill bits.
    Each drill bit requires two inserts—one on the inner cutting edge and one on the outer cutting edge. Replacement inserts are sold separately.

    Carbide-Tipped Core Drill Bits for Masonry and Concrete

    Remove a core of material with these hollow bits to make larger holes than fluted masonry bits. They're often used for installing pipe and conduit through brick and concrete. The carbide tip resists wear and heat to stay sharp.
    Hex Shank for Rotary Only Drilling
    Image of Product. Front orientation. Drill Bits. Carbide-Tipped Core Drill Bits for Masonry and Concrete, Hex Shank for Rotary Only Drilling.
    The hex shape reduces the chance of the shank slipping in the chuck. Pair these bits with hand-held power drills and hammer drills set to rotary-only mode. Because they use rotary action only, they require more pressure to grind up material than other bits.

    Core Bit

    Quickly create large holes in sheets of glass and ceramic using a drill press. These bits drill smoothly through fragile materials, reducing the chance of chipping and cracking. They have a diamond coating, the hardest finish for the longest life. Bits require an adapter (sold separately) to supply coolant during drilling.

    Tight-Tolerance Water-Hardening W1 Tool Steel Rods

    Image of Product. Front orientation. Steel. Tight-Tolerance Water-Hardening W1 Tool Steel Rods.
    Ready for turning in your lathe, these rods are precision ground and held to strict diameter and straightness tolerances. Also known as drill rod. With far less alloy content than other tool steel, W1 is the most machinable we offer. These rods are often used to make hammers, files, and reamers—tools that don't require the dimensional stability of A2 or O1. These rods are also decarb-free, which means any surface flaws created during the manufacturing process have been removed. This makes them even more machinable and leads to better results from heat treating or finishing. Heat treat the surface for extra wear resistance. Or, quench this steel in water to boost its hardness and strength, giving it a sharper, more durable edge for small tools.
