Made from high-quality M-7 High-Speed Steel, Clymer's Rimless Rifle Chambering Reamers are precision tools designed for professional gunsmiths, ensuring a lifetime of service when properly maintained.
The product line includes both Rougher and Finisher Reamers, with Roughers being .010" smaller to save wear on the Finish Reamer when cutting multiple chambers.
These reamers are made to SAAMI specifications, with the 223 Remington Finish Reamer having a solid pilot, integral throat, and are suitable for creating precise chambers in rimless rifle cartridges.
