The xGrind manual chuck for HPS collets is both super precise and easier to use than similar workholding

We offer two types of manual chucks: xGrind HPS & xGrind Hydro

1. xGrind HPS 20 high-precision manual chuck

Developed specifically for high precision tool grinding, the xGrind HPS uses the same innovative collets as the amazing μGrind HPS. The xGrind HPS:

  • Delivers excellent concentricity and repeatability
  • Offers excellent dampening properties for uniform material removal, optimized feed rates, excellent surface finish, and significantly reduced grinding wheel wear
  • Requires a relatively short clamping length on the blank to achieve constant holding force and concentricity
  • Features a tapered profile and smaller nose diameter than hydraulic holders for better wheel clearance and freedom from interference
  • Extremely durable, with very low wear over thousands of clampings, for economical performance
  •  Affordable overhaul and repair option
  • The clamping screw is at a more ergonomic angle than competing systems, reducing the risk of injury
  • Requires half the screw revolutions to clamp, versus other techniques, saving time and making it more ergonomic
  • Handles shanks from 3 to 20 mm (⅛ to ¾ inches)
  • Standard SK50 interface for nearly universal application

2. xGrind Hydro

The xGrind Hydro is a manually activated hydraulic chuck developed by GDS specifically for high precision tool grinding. The xGrind Hydro:

  • Delivers excellent concentricity and repeatability
  • Offers excellent dampening properties for uniform material removal, optimized feed rates, excellent surface finish, and significantly reduced grinding wheel wear
  • Features a tapered profile and smaller nose diameter than other hydraulic holders for better wheel clearance and freedom from interference
  • Tougher than competing systems and can be rebuilt economically for long term use
  • The clamping screw is at a more ergonomic angle than competing systems, reducing the risk of injury
  • NEW SafeGrip protects against slipping, for safe and easy handling
  • Available in three diameters (12, 20 and 32 mm). Each chuck clamps its native diameter plus smaller diameters using standard intermediate sleeves:
    • 12 mm chuck: Sleeves for 3-8 mm
    • 20 mm chcuk: Sleeves for 3-18 mm
    • 32 mm chuck: Sleeves for 6-25 mm
