    Our basic drill bits are also the most versatile. Cut holes in a variety of metals, from the softest aluminum to the hardest steel.
    Jobbers' Length—These bits have the balance of rigidity and length needed for most applications.
    Short Length—The most rigid bits for drilling the straightest holes.
    Extended Length—Drill through panels and thick workpieces with our longest bits. Their length is good for creating deep holes but makes them less rigid than other bits. As a result, they are more prone to wobbling or breaking, especially when drilling hard 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.
    Titanium Nitride (TiN) Coated—Drill at higher speeds and last longer than uncoated and oxide-coated bits, especially on tough materials like hardened steel and nickel.
    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.
    Black/Gold Oxide—Like black oxide, this finish adds wear resistance and reduces friction for improved chip flow. Because it’s less prone to flaking off, it offers better rust protection when bits aren't in use.

    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.
    Jobbers' Length—These bits have the balance of rigidity and length needed for most applications.
    Titanium Nitride (TiN) Coated—Drill at higher speeds and last longer than uncoated and oxide-coated bits, especially on tough materials like hardened steel and nickel.
    Titanium Aluminum Nitride (TiAlN) Coated—The hardest and most wear-resistant coating, especially at high temperatures. These bits are best for hard and abrasive materials, such as iron, titanium, and fiberglass.
    Gold Oxide—Like black oxide, this finish adds wear resistance and reduces friction for improved chip flow. Because it’s less prone to flaking off, it offers better rust protection when bits aren't in use.

    With flutes that lift chips out of the hole, you don't have to stop drilling to clear these bits manually. They improve coolant flow to dissipate heat and prevent clogs that can damage the bit and ruin the hole. High-speed steel is good for general purpose drilling in most metals.
    Parabolic Flute—A U-shaped groove on the flutes cuts faster and clears chips more quickly than high-helix bits, so these are better for drilling deeper holes.
    Jobbers' Length—These bits have the balance of rigidity and length needed for most applications.
    Titanium Nitride (TiN) Coated—Drill at higher speeds and last longer than uncoated and oxide-coated bits, especially on tough materials like hardened steel and nickel.

    Undersized Hardened Multipurpose M2 High-Speed Tool Steel Rods

    Image of Product. Front orientation. Steel. Undersized Hardened Multipurpose M2 High-Speed Tool Steel Rods.
    These rods, also known as drill blanks, have an undersized diameter for machining your own drill bits. They're hardened for increased abrasion and impact resistance. M2 tool steel offers a nice balance of wear resistance and machinability. It has a high molybdenum content, which allows it to maintain sharp cutting edges even at elevated temperatures.

    Cut the cleanest, quickest threads without ever stopping for chips. Made with an oversized shank and hardened high-speed steel, these taps are built to handle the high torque of impact wrenches for smooth, continuous cutting. The rapid hammering breaks up chips and spiral flutes pull them out of the hole, so you never have to pause and reverse to clear them. They can thread both blind and through holes 15 times faster than by hand. They’re a good choice for threading large holes and working with hard metals.
    You’ll need a VersaDrive chuck (sold separately) to install these taps into your impact wrench.
    Titanium Nitride (TiN) Coated—Run at higher speeds and last twice as long as uncoated taps.
    Spiral Flute for Blind Holes—Pull chips back toward the tap so they won't build up in blind holes. When tapping brittle material like iron that creates fine or powdery debris, choose a straight-flute tap.
    Plug Chamfer—Our go-to chamfer type. With a longer taper than a bottoming chamfer, they are easier to turn but won't thread as close the bottom of a hole.

    Drill and thread holes in a single fluid step that’s 15 times faster than by hand. Made with an oversized shank and hardened high-speed steel, these drill taps are built to handle the high torque of your impact wrench to cut material quickly. A built-in pilot starts the hole while the taper chamfer gradually engages material for clean, accurate threads. Your wrench’s rapid hammering helps break and clear chips as you cut, so you don’t need to pause and reverse. This also means these drill taps are less likely to jam on chips and snap. They’re a great choice for quickly preparing threaded through holes in thin materials.
    You’ll need a VersaDrive chuck (sold separately) to install these drill taps into your impact wrench. You can also get chucks for impact drivers (sold separately).
    Titanium Nitride (TiN)-Coated Hardened High-Speed Steel—Titanium Nitride (TiN) coated taps resist heat and wear better than uncoated taps, letting them last up to twice as long.
    Spiral Flute—Taps with spiral flutes keep chips clear by drawing them back toward the tap and out of the hole.

    Cut holes twice as fast as a power drill. Made with an oversized shank and hardened high-speed steel, these bits are built to handle the high torque of your impact wrench without snapping, even in large holes and hard materials such as stainless steel. A built-in pilot with a stepped tip centers the bit, prevents it from slipping, and drills with one third the pressure of standard bits. Since your wrench absorbs kickback, it won’t fight you if the bit snags, reducing wrist strain and fatigue during long jobs.
    You’ll need a VersaDrive chuck (sold separately) to install these bits into your impact wrench. You can also get chucks for impact drivers and magnetic-base drills (both sold separately). For jobs that don’t require the torque of an impact tool, you can fit these bits directly into a 1/2" chuck on a standard power drill.
    Short Length—The most rigid bits for drilling the straightest holes.
    Titanium Nitride (TiN) Coated—Drill at higher speeds and last longer than uncoated and oxide-coated bits, especially on tough materials like hardened steel and nickel.

    Cut a range of hole sizes two times faster than power drills, then thread them 15 times faster than by hand. Made with an oversized shank and hardened high-speed steel, the tools in these sets are built to handle the high torque of impact wrenches without snapping. The drill bits have a built-in pilot with a stepped tip that centers the bit, prevents slipping, and drills with one third the pressure of standard bits. Your wrench’s rapid hammering keeps the taps moving forward for smooth, continuous cutting. Those rapid blows also help break and clear chips as you cut, so you don’t need to pause and reverse, even in large holes and tough materials. Since your wrench absorbs kickback, it won’t fight you when a cutting tool snags, reducing wrist strain and fatigue over long jobs.
    You’ll need a VersaDrive chuck (sold separately) to install the bits and taps into your impact wrench. You can also get chucks for impact drivers and magnetic-base drills (both sold separately). For jobs that don’t require the torque of an impact tool, you can fit these drill bits and taps directly into a 1/2" chuck on a standard power drill.
    Titanium Nitride (TiN)-Coated Hardened High-Speed Steel Tools—Titanium nitride (TiN)-coated hardened high-speed steel tools have a longer tool life than carbon steel. They resist heat and wear better than uncoated tools, letting them last up to twice as long.
    Taper Chamfer—Taper-chamfer taps have 7-10 chamfered threads at the tip for cutting into the workpiece. They require less torque than other chamfer types, making them a good choice for starting threads and tapping through holes. However, a longer taper means that they cannot thread as close to the bottom of closed-end holes.

    Impact Wrench Tap, Drill Bit, and Reamer Sets

    13 Pieces

    With everything but the impact wrench, these sets are the fastest way to prepare holes with a hand tool. They include a selection of cutting tools and a chuck that lets you swap them in and out of your impact wrench. Made with hardened steel, the cutting tools are built to handle the high torque of the wrench without snapping, even in hard metals. This also means the bits cut holes two times faster than with a power drill, and the taps thread holes 15 times faster than with a tap wrench. The rapid hammering breaks and clears chips as you work to prevent jams. Since your wrench absorbs kickback, it won’t fight you if a cutting tool snags, reducing wrist strain and fatigue over long jobs.
    The chucks hold any tool with a VersaDrive hex shank—including countersinks and extractors—so just one chuck and wrench handle any cutting task.
    13 Pieces—Includes a range of drill bits, taps, and step reamers. All cutting tools are coated with titanium nitride (TiN) to hold up at higher speeds and last longer than uncoated and oxide-coated bits, especially on tough materials like hardened steel and nickel.
