Overview
Weighing just 0.16 ounces, the IRWIN 9445 is sized as a single threading tool rather than a multi-piece kit. Its blend material and brushed finish point to a die or thread-chasing tool meant for cleaning up threads on a bolt or rod.
Irwin is a long-running name in cutting and threading tools, and the light weight here fits a single die rather than a kit. The exact thread size isn't listed in the attribute data, so double check that detail on the product page.
- Blend material construction
- Brushed finish
- 0.16 ounce weight

Who it's for
Fits someone who needs one specific threading die to clean up or cut threads on a single bolt or rod size. Not a fit for a shop wanting a full boxed set covering multiple thread sizes.

Performance notes
