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.
To simulate road hazards, the diamond-shot test, which shoots out industrial diamonds against painted panels at minus 4 degrees Fahrenheit, evaluates the chipping resistance
and durability of the coated steel at low temperatures.
The improved particle dispersion has dramatically increased the chipping resistance
and wear resistance of cutting tool inserts, providing a service life up to 1.
