Collets

Lexair’s full-bore, fixed-length, self-contained collet chuck allows full-capacity spindle operation, due to elimination of the drawtube. When using the full bore chuck, spindle capacity is boosted as much as 30 percent, and clamping pressure is unaffected by centrifugal force, regardless of rpm, according to the company.
