With ordinary center punches, you have to focus on holding the tool and striking it squarely. Not with these.
Each consists of two pieces of turned, hardened steel joined by a tightly coiled spring. Just position one tip on the work, draw back the other, then release.
The prick/ center punch has two conical tips with different included angles — the 75° end makes a shallow mark during layout, and the 45° tip makes a deeper dimple to prevent drill bits from skating.
Ribbed for grip, all are hardened to Rc59 and measure 4 1/4″ to 5 1/4″ overall.
