Cut a range of thread sizes with a single tool. These thread mills can also produce both right-hand and left-hand threads. All are made of solid carbide with an aluminum-titanium-nitride (AlTiN) coating, so they have high strength and excellent wear resistance, even when cutting hard and abrasive material. Use them in a CNC machine that allows helical interpolation.

When used for internal threading, thread mills can create threads of any size equal to or greater than the minimum size listed. They leave space in the hole for chips to fall, and a broken thread mill can fall into the hole without damaging the workpiece.

Thread mills for internal threading cut threads more quickly than other thread mills, but the threads they create have a fixed pitch.

Thread mills for external threading cut with single point, producing rounded threads that are commonly used for high-stress fastening applications involving heavy loads and high pressures. Each cuts a single thread pitch.

Thread mills for internal/external threading have a single cutting point that cuts threads in a range of different pitches on both the inside and outside of the workpiece.

The coil-style threads produced by these taps are shallower and more widely spaced than standard thread sizes. Use them for quick threading action with compatible fasteners. They’re made of high-speed steel and are for use on most metal and plastic. The square shank is compatible with tap wrenches and 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. When using them to tap closed-end holes, be sure to leave sufficient space at the bottom for chips to accumulate.

One file restores a range of thread sizes in most hole diameters.

Repair rusted and damaged threads in pipe and conduit. These files are for use in most hole diameters.

Optional file handles slip over the file to provide a comfortable grip.

Sets include multiple tap sizes for threading different hole diameters. Also known as gun taps, all 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. They're made of high-speed steel and are for use on most metal and plastic. With a square shank, they're compatible with tap wrenches and tap holders for drill presses and milling machines. Their plug chamfer starts threads with moderate torque and is good for start-to-finish tapping.

Uncoated taps are strong enough for most tapping jobs but have the shortest tool life.

Taps with a gold-oxide finish produce less friction than uncoated taps, but do not last as long as titanium-nitride (TiN) coated taps.

Titanium-nitride (TiN) coated taps resist heat and wear better than uncoated taps, letting them last up to twice as long. They also last longer than taps with a gold-oxide finish.
