Description: _x000D_ An automatic center punch is a hand tool used to produce a dimple in a workpiece. It performs the same function as an ordinary center punch but without the need for a hammer. When pressed against the workpiece, it stores energy in a spring, eventually releasing it as an impulse that drives the punch, producing the dimple. The impulse provided to the point of the punch is quite repeatable, allowing for uniform impressions to be made. _x000D_ _x000D_ _x000D_ Features: _x000D_ The tip of this automatic center punch is made from high speed steel for high strength and durability._x000D_ _x000D_ No hammer needed, with this automatic center tool, you can create a dimple in a workpiece quickly and easily._x000D_ _x000D_ Usually used to mark the center of a point, the small dimple guide the tip of the drill and avoids slip or deviation which result in damaging. _x000D_ Suitable for punching on steel plate, aluminum, copper, wood plank and other materials to positioning holes. _x000D_ It is also a great tool kept in car to be used for breaking windows in case there is an emergency. _x000D_ _x000D_ _x000D_ _x000D_ Specifications: _x000D_ Tip Material: High speed steel _x000D_ Handle Material: Brass or Carbon Steel _x000D_ Tip Hardness: HRC58~65 _x000D_ Length: 130mm / 5.12" _x000D_ Handle OD: 13mm / 0.51" _x000D_ Color: Gold, Silver(Optional) _x000D_ Quantity: 1 _x000D_ _x000D_ _x000D_ Package Includes: _x000D_ 1 x Automatic Center Punch 1The tip of this automatic center punch is made from high speed steel for high strength and durability 2No hammer needed, with this automatic center tool, you can create a dimple in a workpiece quickly and easily 3Usually used to mark the center of a point, the small dimple guide the tip of the drill and avoids slip or deviation which result in damaging 4Suitable for punching on steel plate, aluminum, copper, wood plank and other materials to positioning holes 5It is also a great tool kept in car to be used for breaking windows in case there is an emergency
