Brownells Barrel Liner Drill, .22 Liner, .315'' (8Mm)

The Brownells Barrel Liner Drill in .22 caliber is a precision gunsmithing tool built for gunsmiths and serious firearms enthusiasts tackling barrel relining and restoration projects. This high-speed steel drill is engineered to create the exact bore geometry needed to install a .22 barrel liner, with a 0.315-inch major diameter and 0.216-inch pilot diameter. Whether you're restoring a vintage rifle or extending the life of a worn barrel, this drill delivers the precision fit that's critical to maintaining accuracy and structural integrity.

Barrel liner work demands accuracy that generic drills simply can't deliver. This Brownells drill is designed specifically for the job—15-1/16 inches overall with a 1-inch pilot that guides the cut and keeps the bore straight and true. The high-speed steel construction handles repeated use without dulling, and it'll work on barrels up to 25 inches in length. The result is a uniform bore that accepts the liner without gaps or inconsistencies that would compromise performance or cosmetics.

Gunsmithing is as much about respecting the firearm as it is about improving it. This tool helps you do both: you get the precision fit necessary for a professional installation, and you preserve the original character of the rifle you're working on. It comes packed in a protective plastic case, ready to pull out and use when your next restoration project lands on the bench.
