The WILLIAMS COMFORT PRODUCTS PS-4 is a 4-piece center punch set designed for layout and marking work on metal surfaces. Center punches create precise indentations that guide drill bits and prevent walking at the start of a hole. This set is suited for use in mechanical, HVAC, plumbing, and electrical service environments where accurate hole placement is required. Weighing 0.926 pounds, the set is compact enough for a standard tool bag or service van. Tradespeople who regularly drill into sheet metal panels, electrical enclosures, or pipe hangers will find this a reliable addition to their layout toolkit.
The PS-4 is appropriate for general trade use across residential and light commercial service work. It is commonly used by HVAC technicians marking sheet metal for cutouts, electricians locating knockout positions, and plumbers marking pipe hanger locations. The set format provides multiple punch sizes in a single package, making it practical for technicians who encounter varied material thicknesses on the job.
Designed as a general-purpose center punch set suitable for use across mechanical and trade service applications involving metal layout and drilling preparation.
Center punches are hand tools used with a hammer or mallet and require no power source. Always wear appropriate eye protection when striking a punch, as metal chips or fragments can be ejected. Ensure the workpiece is secured before marking to prevent movement. Store punches with tips protected to maintain point accuracy and prevent injury.
