Ripley Cablematic CB-117K Coring Bit Kit for CST 750 Coring Tools - 750 kcmil (Green)

The Ripley Cablematic 31520 (Blade Model CB-117K) is the genuine replacement coring bit kit for the CST750 combination coring, sheath-stripping, and chamfering tool. It is designed specifically for use with 0.750" hardline coaxial cable and provides the spiral-fluted, heat-treated cutting action needed to cleanly remove the foam dielectric core from the cable end, exposing the center conductor for connector termination. This is the correct OEM replacement for cable TV and broadband infrastructure technicians who need to restore their CST750 to factory performance without replacing the entire tool.

The 31520 coring bit kit is compatible with both CST750 configurations: the standard model (Ripley Part #32110, built-in 3/8" drill adapter) and the ratchet model (Ripley Part #32150, separate 3/8" drill adapter), and Ripley lists the same kit for the QCST 750T. Both CST750 versions use the same Guide Sleeve (Part #29111) and accept this same coring bit assembly. The CST750 is rated for CommScope® P3, Times Fiber T10, and Alcatel / Benelux ACE/ACW cable - all of which this replacement kit supports. The replacement sheath-cutting blade for CST series tools is also sold separately (Part #14907). For technicians working across multiple cable diameters, Ripley offers equivalent coring bit kits for the CST500 (CB-115K / Part #31320) and CST875 (CB-118K / Part #31620) tools in the same product line.
