Screw Thread Dies
Use these dies to create external threads on bolts, studs, and rods. They're shaped for use with a die wrench. Loosen and tighten the die with the included set screw to adjust thread depth.
Carbon steel dies are for use on most metal and plastic. Uncoated high-speed steel dies last longer than carbon steel dies when cutting similar material. Titanium-nitride (TiN) coated high-speed steel dies provide up to twice the tool life of uncoated high-speed steel.
Ridgid Dies for Cutting Screw Threads
Use these dies with Ridgid pipe and conduit threader die heads on Ridgid pipe and conduit threaders.

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.
