Our Stinger Tooling Set is designed to work with stock NEPT tubes 1 lb (.75" ID) x 3.75" L. Drill jigs are machined from aluminum with an appropriately-sized hole positioned at the correct height and angle to drill the vent hole consistently every time. These jigs are designed to slip directly over the tube and can be use while the tube is on the spindle. A drill bit is also included with each drill jig.

Set includes:
Universal base
Removable bronze spindle, aluminum rammers, and stainless puller

Each tooling set is machined from 6061 aluminum and bronze. All bases and rammers are chemically blackened, surface hardened, marked with no-pass and swap rammer lines, and engraved with tool set name and tube length.
