The Ripley Cablematic 33757 is the factory-specified replacement coring blade 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 blade 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.

Note that this kit covers the coring bit only. 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 blade kits are the CB 132K (part 33752) and CB 134K (part 33762), respectively.
