Overview
Measuring 4 inches with a 1/8 inch tip, the Starrett 117C is a metal center punch weighing just over an ounce. Its small size and metal handle point to precision marking work rather than heavy demolition.
Starrett has built its name on machinist and metrology tools, and a punch this light and this precisely dimensioned fits that lineage. A 1/8 inch tip is fine enough for marking drill start points on metal without leaving an oversized dimple. At just over an ounce, it is meant to be controlled by hand and struck lightly, not swung like a demolition tool.
- 1/8 inch tip diameter
- 4 inch overall length
- 1.06 ounce weight
- Starrett 117C model
Who it's for
Fits machinists, metalworkers and hobbyists who need a precise center punch for marking drill points on metal. Not the right tool for anyone needing a heavier punch for masonry or rough construction work.
Pros and cons
- Precise 1/8 inch tip for accurate drill point marking
- Lightweight and easy to control by hand
- Compact 4 inch length keeps hands clear
- Too light and fine for heavy demolition work
- Single fixed tip size limits versatility
Performance notes
A 1/8 inch tip diameter is narrow enough to create a small, precise starting dent for a drill bit without wandering across the metal surface. At 1.06 ounces the punch is light enough to hold steady with one hand while striking lightly with a hammer in the other. The 4 inch length keeps knuckles clear of the work surface during use.
