Engis HS14502 B-13974 .2695x2.00 325 CBN Bore Finishing Tool

The Engis HS14502 (drawing B-13974 Rev. A) is a new CBN (Cubic Boron Nitride) bore finishing tool measuring 0.2695 inches in diameter by 2.00 inches in length, with a 325-grit abrasive specification, designed for precision bore finishing and honing operations on ferrous and hardened materials. CBN superabrasive tools of this type are used in single-pass or reciprocating bore finishing to achieve tight dimensional tolerances and fine surface finishes in hardened steel bores, cast iron, and similar hard ferrous workpieces where conventional abrasives would wear rapidly. The 325-grit designation indicates a fine finishing grade, producing smooth surface finishes (typically Ra in the sub-microinch range) suited to final sizing operations rather than aggressive stock removal. This tool features a helical flute geometry visible in the photos, consistent with Engis's bore finishing mandrel/tool design intended for use with compatible Engis honing or bore finishing equipment and fixtures. Sold new in original Engis packaging.
