It is usually used to mark the center of a hole when drilling holes. A drill has the tendency to "wander" if it does not start in a recess. A center punch forms a large enough dimple to "guide" the tip of the drill. The tip of a center punch has an angle between 60 and 90 degrees. It gives a physical resting place for a drill bit so it stays right where you want your hole to be. Features Hardened and tempered square head centre punch Knurled rubber grip Use a center punch for bits up to (arguably including) 1/2" in diameter Prevents drill bit skidding about a metal surface
