Overview
The Irwin 9742 is a small threading tool finished in brushed steel and weighing just 0.8 ounces. Its featherweight, single-size build points to spot thread work rather than a full tap and die kit.
Beyond material and finish, the listing gives little to go on, so exact cutting geometry is not confirmed here. What the numbers do show is a tool built for portability over bulk, at well under an ounce.
- Brushed steel finish
- 0.8 ounce weight
- One size compact body
- Irwin hand tool brand
Who it's for
Fits someone who wants a light, pocketable tool for occasional thread work from a known hand tool brand. Not a match for a shop needing a graduated tap and die set.
Pros and cons
- Brushed finish resists corrosion better than raw steel
- Very light at 0.8 ounces for a tool bag
- Compact one-size build travels easily
- No description or spec detail beyond finish and weight
- Single threading tool, not a full graduated kit
Performance notes
With only a material blend and brushed finish listed, its performance story is mostly about weight: at 0.8 ounces it carries easily in a pouch, favoring portability over the reach of a multi-piece kit.
