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.
