    Carbide-Tipped Drill Bit Sets 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.

    Countersink Sets for Screws

    Image of Product. Front orientation. Countersinks. Countersink Sets for Screws.
    Cut cone-shaped recesses for screws of various diameters so the screw head sit flush with the surface. Choose an 82° countersink angle for inch screws or a 90° countersink angle for metric screws.
    High-Speed Steel—These versatile, wear-resistant countersinks cut cleanly in most materials, including plastic, aluminum, and steel.
    Carbide—The hardest and most wear-resistant countersinks you can buy. They stay sharp at high temperatures and faster speeds for the best performance on hard and difficult-to-machine materials. They last 10 to 20 times longer than their closest alternative, cobalt steel. Carbide can be brittle, however, so use a rigid machine tool holder to prevent breakage.
    Titanium Carbon Nitride (TiCN) Coated—The smooth finish reduces friction, so gummy materials such as aluminum are less likely to stick and build up. The coating also makes these countersinks harder than uncoated countersinks for greater wear resistance.
    Titanium Aluminum Nitride (TiAlN) Coated—For even greater wear resistance at high temperatures than uncoated carbide, the coating on these countersinks lets you cut through iron, titanium, and other metals up to Rockwell C50.
    Aluminum Titanium Nitride (AlTiN) Coated—Our hardest and most wear-resistant coating. These countersinks cut through hardened steel and other metals up to Rockwell C70 without losing their sharp cutting edges.
    Number of Flutes—Countersinks with fewer flutes are best for aggressive cutting. They leave more room for chips to clear, reducing friction and heat. Countersinks with more flutes spread the cut across more edges for better stability, a smoother finish, and longer tool life.

    Impact Wrench Reamer Sets for Hole Alignment

    Image of Product. Side1 orientation. Reamers. Impact Wrench Reamer Sets for Hole Alignment.
    Image of Attribute. Front orientation. Contains Annotated. Reamers. Impact Wrench Reamer Sets for Hole Alignment.
    Driven by the high torque of an impact wrench, the reamers in these sets enlarge holes of various diameters to correct misalignment and overlap faster than with a power drill. The tapered shape fits into narrow holes and makes more contact than straight reamers when removing material. Also known as bridge and car reamers.
    VersaDrive Hex Shank
    All VersaDrive tools have the same hex shank, so you need only one chuck (sold separately) to fit them into your impact wrench. This lets you quickly switch from your reamer to a drill bit, tap, or any other cutting tool you need to complete the next job. For jobs that don’t require the torque of an impact tool, you can also fit these reamers directly into a 1/2" chuck on a standard power drill.
    Do not use these reamers on holes that were flame or plasma cut.
    Spiral Flute—Since these reamers clear chips better than straight flutes, they leave holes with a smoother finish. They're better for holes with breaks in the surface, such as a keyway, because they cut continuously across the breaks instead of moving in and out.
    Titanium Nitride (TiN)-Coated Hardened High-Speed Steel—Coated to create less friction than uncoated high-speed steel reamers, these run faster and last twice as long. They’re also hardened for increased wear resistance, making them good for cutting hard metals.
    Left-Hand Spiral—These reamers push chips downward as they cut, so they're often used in through holes.

    Impact Wrench Tap Sets

    Image of Product. Front orientation. Taps. Impact Wrench Tap Sets.
    Tap holes with a range of thread sizes 15 times faster than by hand. Made with an oversized shank and hardened high-speed steel, the taps in these sets are built to handle the high torque of impact wrenches to cut material quickly. Your wrench’s rapid hammering keeps these 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. This also means the tap is less likely to jam on chips and snap.
    You’ll need a VersaDrive chuck (sold separately) to install these taps into your impact wrench. You can also get chucks for impact drivers (sold separately).
    Hardened High-Speed Steel—Multiple Tap Thread Sizes
    Titanium Nitride (TiN) Coated—Run at higher speeds and last twice as long as uncoated taps.
    Taper Chamfer—Good for both starting holes and threading through holes. These taps have the longest taper to gradually engage with the material, reducing the force needed to turn them. They can't reach the bottom of blind holes, however, so you will likely need to finish with a bottoming-chamfer tap.

    Cut the cleanest, quickest threads in a range of sizes without ever stopping for chips. Made with an oversized shank and hardened high-speed steel, the taps in these sets 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.

    Countersink Sets for Lathe Centers

    Image of Product. Front orientation. Countersinks. Countersink Sets for Lathe Centers.
    Cut holes for a range of lathe-center diameters. The 60° angle creates a precise recess for both rotating and stationary lathe centers, keeping your workpiece aligned as it spins.
    High-Speed Steel—These versatile, wear-resistant countersinks cut cleanly in most materials, including plastic, aluminum, and steel.
    Carbide—The hardest and most wear-resistant countersinks you can buy. They stay sharp at high temperatures and faster speeds for the best performance on hard and difficult-to-machine materials. They last 10 to 20 times longer than their closest alternative, cobalt steel. Carbide can be brittle, however, so use a rigid machine tool holder to prevent breakage.
    Titanium Carbon Nitride (TiCN) Coated—The smooth finish reduces friction, so gummy materials such as aluminum are less likely to stick and build up. The coating also makes these countersinks harder than uncoated countersinks for greater wear resistance.
    Titanium Aluminum Nitride (TiAlN) Coated—For even greater wear resistance at high temperatures than uncoated carbide, the coating on these countersinks lets you cut through iron, titanium, and other metals up to Rockwell C50.
    Aluminum Titanium Nitride (AlTiN) Coated—Our hardest and most wear-resistant coating. These countersinks cut through hardened steel and other metals up to Rockwell C70 without losing their sharp cutting edges.
    Number of Flutes—Countersinks with fewer flutes are best for aggressive cutting. They leave more room for chips to clear, reducing friction and heat. Countersinks with more flutes spread the cut across more edges for better stability, a smoother finish, and longer tool life.
