Overview
Designed for revolver maintenance work, this reamer is intended to remove burrs and roughness from the inside of Ruger “Six” Series double-action and S&W K/L/N crane assemblies. It also serves to restore crane dimensions after stretching, helping return the part to proper size. Brownells describes it as a precision-ground, hardened tool steel reamer with six straight cutting blades and a Tenite handle. For serious shooters and gunsmiths working on these revolvers, it is a focused shop tool rather than a general-purpose accessory.

- Intended to remove burrs and restore dimensions, which means it is a corrective tool rather than a routine maintenance accessory.
- The 7 1/2" overall size may be less convenient for compact tool kits or field carry.
- Tool steel construction and a Tenite handle are practical, but the product data does not indicate any included case or storage protection.
