Clymer Pistol Chambering Reamers Rimmed Finisher Style Reamer .357 Magnum

Pistol chambering reamers by Clymer, high-speed steel. These are precision tools for the professional gunsmith and will give a lifetime of service when properly cared for.

Available in two pilot diameters: Barrel for Single Shot or Semi-Auto pistol and rifle barrels; Cylinder for Revolver cylinders.
