STARRETT 18C 56757 Automatic Center Punch, Adjustable Stroke, 11/16 Inch Dia.

Starrett 18C automatic centre punch is ideal for making marks on metal surfaces without using a hammer.

Working Mechanism:

• As the punch is depressed, the downward force from the pin to the punch bears on the hammer mass and pushes it back against its spring, storing energy in the hammer spring.
• The hammer spring will eventually expand as the accumulated energy is released.

Features:

• This centre punch features an internal mechanism that offers perfect centre indentation when downward pressure is applied.
• It strikes heavier blows than standard programmed focus punches and comes equipped with an adjustable knurled cap.
• This tool provides spring tension to regulate the blows while creating marks to offer uniformity in dimple size and depth at each setting.
