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

Also known as gun taps, the taps in these sets have spiral-point flutes that push chips ahead of the tap and out of through holes. Because they don't need to be reversed to prevent buildup, they produce threads more efficiently than standard taps and are suitable for production work. Taps have a square shank for compatibility with tap wrenches and tap holders for drill presses and milling machines. With a plug chamfer, they have 3-5 chamfered cutting threads, so they're suitable for start-to-finish tapping. All taps and drill bits are made of high-speed steel for use on most metal and plastic.

Also called subland drill bits, these bits countersink as they drill to prepare holes for tapping. The 90° countersink angle guides the tap into the hole. The drill bit diameter will not change after sharpening.

Repair damaged threads or create new ones. These convenient assortments include helical inserts, an installation tool for each thread size, a drill bit, and a tap. The inserts are also known as Heli-Coil inserts.

Quickly restore stripped threads—these inserts come with through-hole taps and installation tools. The tough coils on these inserts expand once installed to anchor in a tapped hole.

Drill holes and cut threads without switching tools. Made of high-speed steel, these taps are for use on most metal and plastic. The square shank is compatible with tap holders for drill presses and milling machines. All have a plug chamfer with 3-5 chamfered cutting threads, so they're suitable for start-to-finish tapping.

Thread these chucks onto the spindle of portable drills and stationary machines to hold bits. They're a keyed chuck, so they hold the bit tightly, preventing it from slipping under load. Use the included key to tighten and loosen the jaws. If your machine doesn’t have a threaded spindle, mount them with a threaded drill chuck arbor.

To maximize grip and minimize wobble, choose a chuck where your drill bit diameter falls in the middle of the shank size range.

Made of stainless steel, these chucks maintain smooth, precise operation even when exposed to moisture and chemicals. They're keyless, letting you swap bits in and out with a quick twist of the sleeve. Use them for low-torque, high-speed drilling. As torque increases, their grip tightens on the bit. Mount them to the threaded spindles of handheld drills. For machines without spindles, mount them to a threaded drill chuck arbor.

A through hole allows long bits to pass through without hitting the back of the chuck. They can also be used on an electrical discharge machine to hold electrodes and let fluid pass through.

To maximize grip and minimize runout, choose a chuck where your drill bit diameter falls in the middle of the bit shank size range.

Thread holes 15 times faster than by hand. Made with an oversized shank and hardened high-speed steel, these taps 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).

Even when exposed to moisture and chemicals, these stainless steel chucks maintain smooth, precise operation. They’re keyed, so their jaw locks securely around bits—use the included key to tighten and loosen their hold. Thanks to their grip, they’re great for high-torque, low-speed drilling in hard materials. Mount them to the threaded spindles of handheld drills. For machines without spindles, mount them to a threaded drill chuck arbor.

A through hole allows long bits to pass through without hitting the back of the chuck. They can also be used on an electrical discharge machine to hold electrodes and let fluid pass through.

To maximize grip and minimize runout, choose a chuck where your drill bit diameter falls in the middle of the bit shank size range.

Mill an angled edge to the entire outside diameter of pipe, tubes, and rods in a single pass with more speed and precision than a handheld scraper. These end mills deburr pipe and tube for butt welds and shape rods for sliding into housings and holes. They attach to screw machines, lathes, and drill presses and can be set up to repeat cuts for multiple pipes. Staggered cutting edges reduce vibration, resulting in a smooth finish. They have teeth that distribute cutting force and extend the life of the tool. Made of high-speed steel, they work with a variety of metals.

All you need to machine precise port holes for hydraulic fittings, including a drill bit, port counterbore, and thread mill. These tools meet aerospace and military specifications for leakproof port holes, so fittings stay sealed over time, even during sudden pressure and vibration. With multiple cutting edges, the drill bit roughs out a hole with the right shape for the counterbore to finish. A built-in channel delivers coolant to the cutting surface to reduce heat and flush out chips more efficiently than a standard drill bit can. The counterbore has a pilot that guides the tool as it finishes the hole to the exact size you need for your fitting. Use the thread mill to cut internal threads. The mill leaves enough space in the hole for chips—or even a broken mill—to fall without damaging the workpiece.

All tools are coated with aluminum titanium nitride (AlTiN) to reduce heat as you cut and extend tool life. While they’re most often used to make holes in aluminum and steel, you can also use them on hard metals like stainless steel.
