Coax Cable Core Extractor Tool

Many of our pickups use single-conductor coax cable. Specifically, we use RG-174/U because it is impedance-controlled, fully shielded, small in diameter, and mechanically robust. One tradeoff of using this type of cable is that it can be difficult for installers to work with.

When working with RG-174 and other micro-coax cables, cleanly separating the center conductor from the braided shield is a small operation that can become a major source of frustration. Most commercial coax tools are designed for connector preparation—not for escaping the core through intact braid for soldering to pot lugs or PCB terminals.

This tool exists because we needed a reliable solution in our own production work—and couldn’t find one.

The Bartolini Coax Cable Core Extractor uses a polished thin-wall tube with a long, shallow bevel and a flat plunger to gently part the braid and push the dielectric and center conductor through it. The result is a clean, controlled exit with minimal braid damage and a consistent lead length.

It’s fast, repeatable, and easy to learn—ideal for bench work, small production runs, and repair situations where consistency matters.

Features:
– Designed specifically for the RG-174 we use and similar micro-coax
– Polished bevel tip parts braid cleanly without snagging
– Flat plunger extrudes the core—no hooks or grabbing required
– Supports consistent escape length for repeatable solder prep
– Proven in daily production use before being offered for sale

These are made in small batches using dedicated jigs and assembled by hand. The body and plunger cap are 3D-printed for ergonomics and speed; the working elements are selected and finished for durability and feel. This is a functional production tool, not a decorative accessory.

If you’ve ever thought, “There has to be a better way to do this,” this tool was made for exactly that moment.
