Description:

Finest Workmanship & Quality; Made In USA From M-7 High Speed Steel
Made by Clymer, a truly dedicated group of gun people, from best quality, M-7 High-Speed Steel. These are precision tools for the professional gunsmith and will give a lifetime of service when properly cared for. Fully guaranteed. Roughers are .010" smaller in diameter than the final size, do not cut the throat area and should be used to save wear on the Finish Reamer when many chambers are to be cut. If only a few chambers will be cut, a Finish Reamer is all you need. Superb quality reamers made to SAAMI specifications.

Belted Finisher Style Reamer fits .300 Winchester Mag

SPECS: RIFLE REAMERS - 6, right-hand cutting, straight flutes. Solid pilot, integral throat. Stocked in Rougher and Finisher. 7/16" round shank with 3/8" square drive. ¼" round shank on .22 RF. ORDERING: Advise: 1) Stock #. 2) Cartridge Caliber and Name.
