It has two times the chipping resistance
of conventional products.
Coated with Hitachi's JX coating--a PVD coating that incorporates particles with enhanced self-lubricating characteristics--it has lubricity as well as hardness, heat-resistance, and chipping resistance
that is vastly improved over previous coatings.

of Coatings," in Annual Book of ASTM Standards, 0602, ASTM International, West Conshohocken, PA, p.
Gilkenson says abrasion resistance, chipping resistance
and resistance to heat buildup determine tire life.
Using ultra-fine diamond grains, the cutting edge also offers superior chipping resistance
in milling applications, plus higher feed per tooth, so less inserts are required in a milling cutter.
