Starrett 18A Automatic Center Punch with Adjustable Stroke

These punches and nail sets are universally used, but most often by machinists and carpenters. They are well-proportioned for ease of use. The specially selected tool steel is hardened and tempered to the proper hardness. All of them feature nicely knurled finger grips for ease of handling. A special tempering process makes the head less likely to fracture from a hard, off-center blow. ALWAYS WEAR SAFETY GLASSES WHEN USING STRIKING AND STRUCK TOOLS. Rugged automatic punches have all-steel handles and parts. These punches have a mechanism that automatically strikes a blow when downward pressure is applied. No hammer is required, making one hand always free to steady the work. The adjustable knurled cap regulates the force of the blow. Should a heavy mark be required, the cap is screwed down. Progressively lighter marks are obtained by turning the cap upward. The tension of the spring, which regulates the blow is constant, so marks made by the point are uniform in depth and size for each setting. The point can be easily removed for regrinding and/or replacement. All sizes are identical in style, differing only in the striking power.
