643J Dial Depth Gage 52715

The Starrett 643 Dial Depth Gage has a knife-edge base and a needle point contact which has been hardened and ground. The knife-edge base has a cutout so that the conical point can be precisely positioned for close work. Point is 1/2" (12.7mm) long with a 40º included angle. In action, the inspector gently pushes the point down to read zero with the base and then pushes down to make the needle point contact the workpiece to take the measurement. 0-.125” Range, .0005” Grad, 0-25-0 Dial.
