Overview
The Starrett 18C is a single punch weighing 0.29 pounds.
Starrett has long specialized in precision measuring and machinist tools, and the 18C fits that lineage as a standalone punch rather than a boxed set. The listing gives only weight, with no punch type, tip diameter or overall length specified, so buyers needing a center punch versus a pin punch should confirm that before ordering. At under a third of a pound, it is light enough for one-handed marking work.
- Starrett brand, precision tools
- 0.29 lb weight
- 4.7 average rating
Who it's for
Works for a machinist or hobbyist who needs one punch from a brand known for precision tools, rather than a full punch set. Not the right pick for someone who needs the exact tip diameter confirmed up front.
Pros and cons
- Light 0.29 pound build for control
- Punch type and tip diameter not listed
- Sold as a single tool, not a set
Performance notes
At 0.29 pounds the 18C is light enough for controlled hand strikes and precise marking rather than heavy demolition work.
