Ripley Cablematic CB 133K Coring Bit Kit for CST 650MC - CommScope® MC² 650 Cable

The Ripley Cablematic 33757 is the factory-specified replacement coring bit kit (model CB 133K) for the Ripley Cablematic CST-650MC coring, stripping, and chamfering tool. It replaces the double-helix coring bit used to remove the polyethylene disc or air dielectric from CommScope® (Trilogy) MC² coaxial cable in the 650 size class. This is an essential service part for cable splicers, linemen, and broadband technicians who rely on the CST-650MC for daily cable preparation work.

The CB 133K kit is compatible with both variants of the 650MC tool - the standard T-handle model (CST-650MC, part 33900) and the ratchet-handle model (CST-650MC-R, part 33797). The CST-650MC performs coring, sheath stripping, and chamfering simultaneously in a single operation on aluminum-sheathed CommScope MC2 cable, and maintaining a sharp, properly seated coring bit is critical to achieving clean, accurate cuts that meet splice preparation standards.

The sheath cutting blade (CB 60, part 14907) and guide sleeve (part 33771-3) are separate serviceable components and are sold individually. For technicians also servicing the CST-500MC or CST-750MC, the corresponding coring bit kits are the CB 132K (part 33752) and CB 134K (part 33762), respectively.
