Proto J441/4S2 Prick Punch 1/4 Inch S2 Steel

Product Description

The PROTO J441/4S2 is an S2 steel prick punch designed for layout and marking work in metal fabrication, machining, and general trade applications. With a 1/4 inch punch size and an overall length of 4-3/4 inches, this punch delivers accurate center-starting points before drilling. S2 tool steel provides the impact resistance and hardness needed to hold a sharp point through repeated hammer strikes. The compact 4-3/4 inch length gives machinists, pipefitters, and ironworkers a comfortable, controlled grip during precision layout operations.

This prick punch is suited for use in metal shops, fabrication yards, and field work where accurate scribe-point marking is required before center punching or drilling. The 1/4 inch tip size is a common choice for light to medium layout tasks on steel, aluminum, and other metals. It is typically used by machinists, pipefitters, HVAC fabricators, and general tradespeople who need consistent, repeatable punch marks on flat or curved workpieces.

Installation Notes

Prick punches are hand tools used by machinists and fabricators — no power source or lockout procedure is required. Always wear safety glasses when striking a punch with a hammer. Inspect the punch tip before use; a mushroomed or chipped striking end should be dressed or the punch replaced. Keep the striking face free of oil or grease to prevent the hammer from glancing off during use.
