Starrett 56757 Automatic Center Punch 11/16 in Steel

Product Description

The STARRETT 56757 is an automatic center punch designed for marking center points on metal, wood, and other materials before drilling. The spring-loaded mechanism drives the hardened steel tip without a hammer, allowing one-handed operation in confined or awkward work positions. At 5.25 inches overall length with an 11/16-inch punch tip, this tool delivers consistent, repeatable indentations with controlled impact force. The knurled grip provides positive hand control during use. It is a standard layout and metalworking tool installed and used by machinists, HVAC technicians, pipefitters, electricians, and general trade professionals who regularly drill into metal substrates.

The STARRETT 56757 suits residential and commercial trade work wherever accurate drill-start marking is required. Common applications include marking sheet metal, pipe, structural steel, and conduit before drilling or punching operations. The automatic action eliminates the need for a separate hammer or mallet, making it practical for field service work, bench work, and production environments alike. A single unit is packaged per order.

Installation Notes

No installation is required for this hand tool. Position the punch tip at the desired mark location, apply downward pressure until the internal spring releases, and the tip strikes the workpiece. For use on hardened or thick materials, verify the punch tip condition before use and replace if the tip shows wear. Store with the tip protected to maintain point integrity.
