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.

Battery-Powered Threaded Rod Cutters

Make clean cuts on threaded rod with the pull of a trigger. These battery-powered cutters require less time and exertion than manual threaded rod cutters and hacksaws, so they’re good for construction and other jobs with lots of cuts; a single battery charge cuts about 350 rods. Since you’re not tethered to an outlet, you can cut rod that’s already installed.

Unlike tools that cut with a fast-moving blade, such as circular saws, these cutters have a die that cuts smoothly and leaves no burrs. These dies won’t bind and seize or send sparks and chips flying. To switch between threaded rod sizes, just rotate the cutting die.
