Our high precision German grinding wheel adapters from GDS meet or exceed all OEM specs. And because our markup is small you get a great deal! We stock the most commonly used WALTER, ANCA, and Rollomatic adapters in the US for immediate delivery, plus the stepped EWAG Compact Line adapter and some of the more popular Reinecker adapters. Vollmer VGrind adapters are due in October. We offer all the major brands, to include adapters for dressing, presetting, and balancing. But given the popularity of these adapters and long lead time we strongly encourage you to order in advance!

Maximizing the life of your grinding spindle and producing high quality tools both require flawless grinding wheel adapters. Our grinding wheel adapters offer you:

  • Maximum taper accuracy by using constantly controlled and calibrated measuring equipment. For example, all mating surfaces on our HSK adapters are machined to within 10 microns – far better than the DIN standard
  • Absolute accuracy of fit and optimum radial and axial run-out. Most HSK adapters are balanced to G1.6 @ 10,000 RPM
  • Extreme load-bearing capacity, thanks to our use of tempered material and the best heat treating processes (vacuum hardened to 54 Rc)
  • Optimum surface quality and associated long-term dimensional stability and precision, as well as spindle protection, thanks to our finishing processes
