This remarkable new tool grinding chuck from GDS handles shanks from 3 to 20 mm (⅛ to ¾ inches) and lets you change diameters in seconds. Yet from tool to tool, runout remains within two microns at 2½ x D! It even holds under 5 microns TIR after the grind. And it performs like this over tens of thousands of clampings (160,000 in one tool manufacturing test!).
Officially it’s called the μGrind, (i.e. Mu-Grind or Micron Grind). We can’t help calling it the “super chuck.” Either way, prepare to be amazed, watch the video, and reserve yours now!
