The multifunctional steam oxide (Fe2 O4) coating is an adhesive oxide coating with a thickness of 0.010 mm and offers the following advantages:
Improved adhesion of cooling lubricant on the drill surface prevents built-up edges and cold shuts.
Improves chip discharge from the cutter - reduced heat development in the critical zone.
Increased surface hardness - thus improved wear resistance.
