Overview
Starrett's 18C is an automatic punch made from alloy steel. The listing gives its mode and pin hole size but does not describe the tip or the mechanism.
Starrett is a long-established measuring and layout brand, which sets expectations for finish and tolerance. The listing says little about tip shape or stroke, so those need checking separately. The light body fits a tool roll.
Who it's for
A machinist or maker marking work with an automatic punch will find a plain alloy steel tool here. Shoppers who need spring tension or tip geometry spelled out should look for a listing that states it.
Pros and cons
- Alloy steel construction
- Light for its type
- Original version listed
- Tip style not listed
- Spring tension not described
- No use case in listing
- Single punch only
Performance notes
An automatic punch releases at a set pressure so the mark depth stays consistent from one hit to the next. The listing does not give the spring rate or tip geometry. Alloy steel supports repeated use.
