1911 Pin Hole Reamers by Brownells are designed to true-up pin holes in 1911 frames for a tight, smooth-operating pistol.
The reamers are made of hardened steel with fluted shanks and have hand-filling polymer handles for a comfortable grip and effective torque transmission.
These reamers are essential for custom pistol building, especially for correcting out-of-round and under-size pin holes.
