Use to polish after using 45° Chamfer Cutters; or for lapping out dings, sharp edges, etc., by itself. Improves accuracy. Use with abrasive paste - like our Silicon Carbide grits - mounted in variable speed electric drill. Made of half-hard brass to hold polishing grit well without excessive tool wear.
Our Chamber Reamers are individually hand-stoned to cut smooth and chatter free. Made to SAAMI specifications or custom specifications for standardized cartridges and to the current industry standard for popular wildcat cartridges. All HSS reamers have a 3/8" square drive shank. 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.
