Our Coatings

Standard Coatings

To optimize your CNC machining results and maximize both your part finish and tool life, opt for one of Helical Solution's premier coatings: Zplus, Aplus, Tplus, and Nplus. Each coating is optimized 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.

Zplus

Zplus provides higher hardness, lubricity, and abrasion resistance. While it's specifically engineered for aluminum applications, it is also an optimal coating for other non-ferrous materials. Zplus holds up well in abrasive materials and reduces the chance of built-up-edge in softer, gummy alloys.
