270 Win. Short Mag. (WSM) CIP Finish Chamber Reamer

For Rougher and resizer use 270 Winchester Short Magnum (WSM) SAAMI Chamber Reamer

Due to (?L) Problem All CIP Reamers are built to production size +.0015 to +.002 over on finishers unless otherwise specified.

All HSS reamers have a .4375 Diameter shank and 3/8" square drive shank unless otherwise specified. Carbide reamers feature a .4375" cylindrical shank. We can grind a square drive on a carbide reamer, but we do not recommend driving a carbide reamer with square drive - the carbide tends to chip and/or shatter. Premium reamers feature removable pilots that are held in place with a screw. Premium reamers include one bushing of nominal bore diameter. Reamers are available in Carbide for production run needs: Please contact a sales associate if you have any questions or if you would like to order a carbide reamer.

Tolerance for Resize (Die) Reamer is std die mfg. specifications of -0.0035 to -0.004 on body and the diameter specified on the neck - Tolerance for Rougher is -0.009, unless noted.
