NSK GRS Compatible Ultra 850 Rotary Handpiece

The NSK T815001 Ultra 850 Rotary Handpiece is an air-powered, high-speed rotary handpiece made by NSK of Japan to exacting manufacturing standards. Widely used as a compatible accessory with most Glendo GRS Air Systems, it delivers rotational speeds of up to 320,000 RPM for precise, efficient cutting in engraving and stonesetting applications.

The Ultra 850 features a permanent lubrication design engineered for long service life with minimal maintenance. Its flexible tubing reduces operator hand fatigue during extended continuous use. A built-in Chip Air Mechanism continuously blows away cutting powder to improve cutting efficiency and reduces heat generated during cutting, further extending the service life of the bur.

This handpiece connects directly to the GraverMax, GraverMate, GraverMach AT, and GraverMax G8, as well as any regulated air supply. Due to its extremely high operating speed, the Ultra 850 accepts only 1/16" diameter (0.062" / 1.6 mm) bur shanks.
