1Automatic center punch is a tool with a tapered tip used to make indentations on objects. This allows you to safely drill holes in the same position without slipping. 2Made of hardened steel and has knurled finger grip for easy operation and better punching control. Its tempering head is less likely to break due to eccentric blows. 3Center punch has a mechanism that automatically strikes when downward pressure is applied. There is no need for a hammer, and one hand can be freed at any time to work stably. 4For heavier markings, tighten the lid. By turning the lid upward, you can get a gradually shallower sign. The depth and size of each set of the tip sign are the same. 5Removable tip, the tip can be easily removed for regrind and/or replacement.
