Our ISO50 collet chuck holder is built for CNC machining centers that need extra rigidity for holding ER collets on larger-diameter tooling. Manufactured to the DIN2080 standard with Taper Angle Class AT3 accuracy, the taper is held to a precise angular tolerance for consistent, repeatable seating in the spindle — unlike lower-grade holders that shift slightly with every tool change.
Runout between the internal collet bore and external ISO50 taper is held to within 0.005mm, so the collet — and whatever tool it's clamping — runs true even under the heavier cutting loads ISO50 tooling typically handles. This concentricity is checked and ground on a Studer precision grinding machine, known for delivering some of the tightest dimensional tolerances in the industry, rather than a standard cylindrical grinder.
Every holder is dynamically balanced after grinding — not before — so the balance certificate reflects the actual finished geometry of the part you receive, not a pre-finish blank.
