Made from high-quality M-7 High-Speed Steel, Clymer's Rimless Rifle Chambering Reamers are designed for professional gunsmiths and ensure longevity with proper care.
The reamers come in two types: Roughers, for initial chambering to reduce wear on the Finish Reamer, and Finishers, for the final chamber size.
These precision tools are made to SAAMI specifications, with options for the 222 Remington cartridge, and feature right-hand cutting with straight flutes and a solid pilot with an integral throat.
