Our Coatings
Standard Coatings
To optimise your CNC machining results and maximise both your part finish and tool life, opt for one of Helical Solution's premier coatings: Tplus and Dplus. Each coating is optimised for a specific material group, and is designed specifically to provide superior tool hardness and strength, and aid in the chip evacuation process by increasing lubricity within flute valleys.

Dplus delivers unmatched tool life in aerospace aluminium, graphite, abrasive composites, and other non-ferrous applications. Featuring a tetrahedral amorphous carbon (taC) bond structure, this coating offers an extremely low coefficient friction and exceptionally high hardness, allowing it to resist abrasion while maintaining a sharp cutting edge. Dplus is part of our DLC family of coatings.
