The .005 relief returns for the remainder of the tip's periphery. The burnishing pad provides the fine hole finishes common with gun drilling. As this pad does not extend 180Âº from the cutting land, measurement by micrometer will indicate a false reading of about .001 to .002 under the gun drills true diameter. The drill is truly on size! A pilot hole or drill bushing to start the gun drill must be sized to the gun drills marked diameter +.0002 to .0005, NEVER undersize. What is the maximum hardness for gun drills?
