The Best performance

KleinDIA® is a DLC (Diamond-like Carbon) anti-friction coating which allows to solve problems of tool abrasion, chip evacuation and chemical attack. A layer of apprx. 1 micron is laid on the tool surface at low temperature, thus not altering the properties of the router bit or knife.
Its high hardness is granted by both Sp2 (Graphite) and Sp3 (Diamond) carbon hybridisation.

TECHNICAL FEATURES and BENEFITS

• High hardness Hv0,025: 2500-3100
• Higher wear resistance, longer tool life
• Low frictional coefficient, less heat and wear
• Very low sticking coefficient, superior chips evacuation
• Thickness: apprx. 1 micron
• Colour: bright black
