The Ripley Cablematic 31230 is a 3/8" drill adapter accessory designed for CST-R (ratchet handle) coring, stripping, and chamfering tools used on 412 to 840 kcmil coaxial and utility cable. Unlike standard "T" handle CST models — which have a drill adapter built in — the CST-R ratchet handle variants require this separately purchased adapter to enable power drill operation. It is the correct replacement accessory for linemen and cable splicers who need to drive their CST-R tool with a standard 3/8" drill chuck rather than turning it by hand.

Installing the adapter is straightforward: remove the ratchet handle assembly by loosening hexagonal screw "B," then seat the 31230 adapter shaft into your drill chuck. Ripley recommends operating at low RPM for best coring results and to protect the cable end. This adapter is designed to pair with the Part 31250 ratchet handle for the 412–840 range and is used alongside the CB 60 sheath cutting blade (Part 14907) as part of a complete CST accessory setup.

The 31230 covers the 412 to 840 kcmil cable size range only — it is not interchangeable with Part 31235, which is the drill adapter for the larger 860 to 1160 kcmil range. Confirmed compatible cable types include CommScope P3, Times Fiber T10, Times Fiber TX, and Alcatel Cable Benelux ACE/ACW. If you are unsure which adapter your job requires, verify the cable's kcmil rating before ordering.
