Alignment Reamer

Alignment Reamers by Triumph are specially designed for toughness and precision.  These alignment reamers are cut with a counter-clockwise spiral which reduces wedging and breakage.   The 3 flatted shank prevents slippage.  Made with high quality steel and finished with bronze oxide, these bits can withstand the high temperatures created in normal use.  The high speed steel will also keep its edge better than other materials and resist chipping and wear.  This will give you a cleaner finished product.
