The Ripley Cablematic 33762 (blade model CB 134K) is the replacement coring bit kit for the CST-750MC Coring and Stripping Tool, designed specifically for 750 kcmil (0.750") cable. The coring bit removes the polyethylene disc or air dielectric material from the cable center to expose the center conductor, completing a critical step in cable termination and connector preparation. This kit is the standard choice for linemen and cable splicers working with CommScope (Trilogy) MC2 750-size cables on coaxial and hardline CATV plant installations.

The CB 134K features a double helix coring bit geometry engineered specifically for PE disc and air dielectric cable constructions, producing fast, precise coring with a smooth, beveled edge on the finished dielectric face. The heat-treated replacement bit is a direct drop-in for the CST-750MC tool body — no need to replace the full coring tool when the bit wears. The CST-750MC accepts both the standard T-handle for manual operation and a 3/8" drill adapter for power-driven use, and the CB 134K blade kit is compatible with either operating mode.

The CST-MC coring blade kits are cable-size specific — this 33762 kit is correct only for the 750-size variant of the CST-MC tool. For 500-size cable use part 33752, and for 650-size cable use part 33757. After coring, residual dielectric material on the center conductor can be removed with a compatible center conductor cleaner (CC-100, CC-200, or CC-200EUR, sold separately). The sheath cutting blade for the CST-750MC is a separate replacement item (part 14907) and is not included in this coring bit kit.

• Double helix coring bit design optimized for fast, precise coring of PE disc and air dielectric cables
• Produces a smooth, beveled edge finish on the cored cable dielectric face
• Heat-treated replacement bit for extended service life under field conditions
• Drop-in replacement for the CST-750MC — replaces the worn coring bit without replacing the tool body
• Compatible with both manual T-handle and power (3/8" drill adapter) operation of the CST-750MC
• Cable-size specific: matched to 750 kcmil (0.750") CommScope (Trilogy) MC2 and equivalent PE disc/air dielectric cables
