The RSCT-860QR stripping/coring tool is two tools in one. RSCT cable strippers remove the aluminum sheath without scoring, while the cable coring function cores the dielectric and bevels the outer conductor on hardline cables. SCT stripping/coring tools work on 0.412″ through 1.000″ hardline cables, including PIII, T10, TX10, CommScopeŽ Power Feeder, Times Fiber 50-ohm, PB10, MC2, and comparable HFC cables. This part is the Cable Prep brand RTH ratchet T-handle. Either handle can be removed for operation with a 3/8-inch variable speed drill.
