Fully automatic single hand operated, spring loaded steel punch is useful for light marking jobs on metal. Round shank has clean and well cut knurling for non-slip grip. Hardened tool steel tip is removable and can be easily resharpened.
Built-in mechanism delivers punch just by pressing on the head- no heavy hammering needed.. For varying depth of impression, just turn the knurled head. Screwing the cap downwards produces heavy indentation and lighter markings can be obtained by screwing the cap upwards

Once the knurled cap is set to the desired position, the punch will strike the same depth every time.
