  • Coating

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.
