Economy Carbon Steel Taps
Often used for thread repair and occasional hand tapping, these carbon steel taps can thread holes in most metal and plastic, but they have a shorter tool life than standard taps.
Taper-chamfer taps have 7-10 chamfered threads at the tip for cutting into the workpiece. This lets them cut with 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 start threads less easily than 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.

Economy Carbon Steel Pipe and Conduit Thread Taps
Use these carbon steel taps for thread repair and occasional tapping of pipe and conduit. They can tap threads into most metal and plastic, but they have a shorter tool life than standard taps. 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. When using them to tap closed-end holes, be sure to leave sufficient space at the bottom for chips to accumulate.

Tap and Die Sets
Use a single set for many sizes of internal and external threads. The taps and dies are for use on most metal and plastic. Hex-shaped dies are for thread repair and can be used with conventional wrenches.
Carbon steel taps are 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-chamfer taps. When using them to tap closed-end holes, be sure to leave sufficient space at the bottom for chips to accumulate.

Tap, Die, and Drill Bit Sets
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.

Thread Repairing Tap, Die, and File Sets
Repair screw threads in a wide range of sizes. The dies are hex shaped for use with conventional wrenches. The taps have a square shank that's compatible with tap wrenches and tap holders for drill presses and drilling machines. With a plug chamfer, all taps have 3-5 chamfered threads and are suitable for thread repair in both through holes and closed-end holes.

Tap Sets
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.
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.

Pipe and Conduit Tap Sets
Create pipe and conduit threads in a range of hole diameters. With a square shank, these taps are compatible with tap wrenches and tap holders for drill presses and milling machines.
Taps with NPT and BSPT threads have a plug chamfer for start-to-finish thread tapping.
Taps wth BSPP threads have a bottoming chamfer that 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.
Carbon steel taps are for thread repair and occasional tapping.
Tap and Drill Bit Sets
Drill and tap a variety of hole sizes. These taps and drill bits are for use on metal and plastic.
Carbon steel taps are 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.
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.
