November 18, 2014 - Designed with the best combination of total indicated runout (TIR), clamping force and ease of use in mind, the new Rego-Fix micRun clamping system is the most accurate collet system for high-speed machining on the market.

Rego-Fix developed the micRun system for superior, high-precision clamping. It’s available in standard taper types and comprises three precision-tailored and matched components: micRun collets, micRun clamping nuts, and micRun toolholders. When used together in compliance with recommended tightening torque, the components createhigher transferable torque compared to other precision collet systems and provide a TIR of less than 0.00012 in. at 3 x D.

Available with internal or peripheral cooling, micRun features a patent-pending collet locking system that retains the collet in the nut for easier insertion and removal, with no extractor required. The micRun line of collets provides great flexibility with four sizes available: MR11, MR16, MR25, MR32. It also allows 16 different tool diameters ranging from Ø 1.00 – Ø 20.00 mm to be clamped in the same holder, including tools with nominal diameter with shaft tolerance h11.

micRun Clamping Nuts have a special surface treatment that increases the clamping force, and a special thread design keeps the nut aligned with the holder to improve repeatability and rigidity in challenging applications. The nuts, which also have a closed contour design that reduces noise, can be tightened and loosened with a freewheel wrench head. The nuts are available with standard (MR) and fine thread (MRM), and coolant versions for Coolant Flush Disks and Sealing Disks (MRC).
