Williams Comfort Products P-39 Center Punch 5/16 in

Product Description

The WILLIAMS COMFORT PRODUCTS P-39 is a center punch designed for marking precise starting points on metal and other hard surfaces before drilling. With a 5/16-inch diameter point and an overall length of 4-1/4 inches, this tool gives technicians a compact, well-proportioned punch suited for layout and hole-location work. It is a hand-strike tool, used with a hammer to produce a clean, accurate indentation that guides a drill bit and prevents walking. Tradespeople across HVAC, plumbing, electrical, and general mechanical service keep center punches like the P-39 in their kits for sheet metal fabrication, bracket work, and equipment installation tasks.

The P-39 is appropriate for residential and light commercial service work where precise hole placement is needed before drilling into steel panels, mounting plates, or structural members. It is a single-unit tool sold individually, making it easy to replace a worn or damaged punch without purchasing a full set. Its compact length makes it manageable in confined spaces common to mechanical rooms and equipment enclosures.

Installation Notes

Center punches are used by hand-striking the flat end with a hammer — always wear appropriate eye protection when striking. Secure the workpiece before punching to prevent movement and ensure accurate marking. No power tools or special codes apply to hand punch use, but follow all applicable shop safety practices when working with metal fabrication in occupied or energized equipment areas.
