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.

Round dies are for cutting threads. Use them with wrenches for round dies. Hex-shaped dies are for thread repair and can be used with conventional wrenches.

Carbon steel taps are for thread repair and occasional tapping.

High-speed steel taps and dies last longer than carbon steel when used on similar material.

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.

Pipe and Conduit Tap Sets

Set with Fabric Pouch

Set with Wood Case

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. High-speed steel taps have a longer tool life than carbon steel and are suitable for small-scale tapping jobs.
