Text Box: XDS Shoes are used in motor/CT applications to burn over extremely hard targets such as RTTS packers with Carbide slip buttons. The diamond-impreg grit acts much like a diamond grinding rock at light WOB and medium to high RPM to actually grind through the carbide or interrupted cuts in hardened steel. 
We normally supply about 2 to 3 feet of 4140HT tube with the correct Pin up.
