Carbide Taps
These taps are solid carbide with an aluminum-titanium-nitride (AlTiN) coating for high strength and excellent wear resistance. Use them on hard and abrasive material, such as heat-treated metal, nickel, and fiberglass. The extreme hardness of carbide taps means they are brittle, so they’re not recommended for hand tapping. A highly rigid setup, such as a CNC machine, is necessary to prevent the tap from breaking.
Plug-chamfer taps are a versatile choice for most tapping applications. With 3-5 chamfered cutting threads, they require moderate torque and are often used for start-to-finish tapping of through holes and closed-end holes. When using them to tap closed-end holes, be sure to leave sufficient space at the bottom for chips to accumulate.
Bottoming-chamfer taps cut into the workpiece with just 1-2 chamfered threads. This short chamfer lets them thread holes closer to the bottom than other taps, but they require more torque to start threads.

Thread Mills
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.

Hole Makers for Tapping Sheet Metal
Install a bit and a collet (sold separately) and mount on a drill press, milling machine, or CNC machine to use friction heat to melt through sheet metal and quickly produce a hole with a lip. You can then thread the hole with a chip-free machine tool tap (not included). The lip that is formed is approximately three times the material thickness. This hole maker comes with a Morse taper 2 tool holder/cooler that dissipates heat.
