Thank you for purchasing the Ultra-Precision, High-Speed Air Turbine, HTS1501S. HTS1501S was
designed for use on machining centers without rotating the machine s main spindle. HTS1501S uses
an Ultra-precision collet system and is ideal for use with small diameter end mills in mold making
applications. The Air Line Kit(with Lubricator) is used to drive HTS1501S.
Please read this Operation Manual carefully prior to use.
