Raptor Supplies offers a wide range of center, pin and self-center punches, & machinist scribers from Ampco, Brown & Sharpe, Dasco Pro, Mayhew, Proto, Stanley and Starrett to mark the center of a hole for drilling. These high-quality punches have black oxide / blue anodized / blue corrosion-resistant / knurled finish, and a maximum length of 9-1/2 inches. Proto center punches can be used for marking intersecting center lines, hole locations and pilot drill starting points. These high-quality center punches have a single-piece, heat-treated S2 steel body for greater strength and durability, and their parabolic striking end helps to reduce mushrooming and chipping effects. We also offer machinist scribers from General for lifting O-rings and gaskets, and cleaning small grooves in automotive or machining environments. These two-in-one etching tools feature hardened and ground steel needle points that are fixed to the knurled body, with one straight end & the other bent at an angle of 90 degrees. A wide range of these punches & scribers is available in different diameters & materials on Raptor Supplies.
