Cut threads into most metal and plastic. These high-speed steel taps are durable enough for small-scale tapping jobs, but they're not recommended for production use. For better chip flow, choose a tap with fewer flutes.
Drive square-shank taps with a tap wrench or use them in a tap holder for drill presses and milling machines. Uncoated taps are strong enough for most tapping jobs but have the shortest tool life. Titanium-nitride (TiN) coated taps resist heat and wear better than uncoated taps, letting them last up to twice as long. Titanium-carbonitride (TiCN) coated taps have up to three times the tool life of uncoated taps. Their hard, smooth finish offers superior resistance to chipping, wear, and heat.
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.
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. However, they do not start threads as easily as taper chamfers. 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.
Sets include one taper-, one plug-, and one bottoming-chamfer tap.

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.

To tap nickel and other hard material, these cobalt steel taps have high cutting strength. Their spiral flutes keep chips clear, so they don't need to be reversed to prevent buildup. With a square shank, they're 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.
Taps for through-hole threading push chips ahead of the tap and out of through holes.
Taps for closed-end hole threading draw chips back toward the tap while cutting threads, preventing chip accumulation in closed-end holes.
A high helix angle provides the cutting strength needed to tap threads in titanium. These cobalt steel taps have an open flute design that keeps chips clear, so they don't need to be reversed to prevent buildup. With a square shank, they're 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.
Taps for through-hole threading have left-hand spiral flutes to push chips ahead of the tap and out of through holes.
Taps for closed-end hole threading have right-hand spiral flutes. They draw chips back toward the tap while cutting threads to prevent chip accumulation in closed-end holes.
These taps are for use on most metal and plastic. They have a square shank that's compatible with tap wrenches and tap holders for drill presses and milling machines.
Uncoated carbon steel taps are for thread repair and occasional tapping. Use uncoated high-speed steel taps for small-scale tapping jobs. Titanium-nitride (TiN) coated high-speed steel taps resist heat and wear better than uncoated taps, letting them last up to twice as long. Titanium-carbonitride (TiCN) coated high-speed steel taps have up to three times the tool life of uncoated taps. Their hard, smooth finish offers superior resistance to chipping, wear, and heat.
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.
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. However, they do not start threads as easily as taper chamfers. 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.

Cut and repair threads and drill holes in many different sizes. Tap and die wrenches are included. The dies are hex shaped for use with conventional wrenches. The taps are made of carbon steel and are recommended for thread repair and occasional tapping.
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
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. However, they do not start threads as easily as taper chamfers. When using them to tap closed-end holes, be sure to leave sufficient space at the bottom for chips to accumulate.

Inserts come with a through-hole tap and installation tool. Also known as Heli-Coil inserts, they have coils that expand once installed to securely anchor the insert. All have a prong for ease of installation. An installation tool grips the prong and reduces the coil diameter, enabling the insert to fit in tapped holes. Remove the prong to insert the screw.
