850
Ultra High-Speed Rotary Handpiece
NON-LUBE AIR TURBINE
90 DAY WARRANTY
INTRODUCTION
The GRS 850 Turbo Handpiece uses
regular friction grip burs. The rotor
spindle uses a non-lube bearing
and requires no further lubrication.
Work on porcelain, wood and other
materials completely free of the
problems associated with use of
lubricating oils. Turbine exhaust from
the nose of this handpeice helps
keep the workpiece clear of debris.

There are a few things the 850 needs to
work properly, a clean air supply of 30 - 35
psi at 1.34 CFM, regulator/air filter, and
a on/off air switch. We recommend a foot
switch for working convenience and safety.
