Starrett 12901 Center Punch Point 1-3/8 X 5/32 Inches

Product Description

The STARRETT 12901 is a steel center punch point designed as a replacement tip for compatible Starrett center punch handles. It measures 1-3/8 inches in length with a 5/32-inch diameter shank. Center punch points like this are used to create a precise starting dimple in metal workpieces before drilling, preventing drill bit walk and improving hole accuracy. The steel construction provides the hardness needed to mark ferrous and non-ferrous metals cleanly. This part is handled by machinists, pipefitters, HVAC technicians, and other trade professionals who work with sheet metal or structural components requiring accurate hole layout.

The 12901 is suited for use in fabrication shops, field service environments, and maintenance applications where a worn or damaged punch tip needs to be swapped out quickly without replacing the entire tool. It is a single replacement point packaged individually, making it a practical stock item for tool cribs and service vans where center punches see regular use on metal marking and layout tasks.

Installation Notes

Installation of a replacement punch point typically requires no special power tools and is performed by hand or with a small wrench, depending on the handle design. Ensure the handle is clear of any spring tension or locking mechanism before swapping the tip. Inspect the seating surface of the handle for burrs or damage that could affect tip alignment. Wear appropriate eye protection when working with punch tools, as hardened steel tips can fracture under impact if misaligned.
