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.

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.

Pros and cons

Pros
  • Compact enough for tight storage
  • Sized for one specific threading job
Cons
  • Exact thread size not stated
  • Not a multi-size kit

Performance notes

Threading tools like this work by cutting or cleaning up external threads as the die is turned onto a bolt or rod. At 0.16 ounces, its size fits a single die rather than a boxed set with multiple thread sizes.
