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. 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.

Bearing-Locknut Shaft Thread Repairing Dies

Clean and restore the fine threads on power transmission shafts that are used with bearing locknuts. These dies also remove thread-locking compound that has built up in the threads. All are hex shaped for use with conventional wrenches. Dies are sized according to the American Bearing Manufacturer's Association (ABMA).

Carbon steel dies are for use on most metal and plastic. High-speed steel dies last longer than carbon steel when cutting similar material.

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.
