Proxxon Step Clamp Set — Pair, MICROMOT T-Slot (11.5×11×4mm), Steel, for MF 70 & KT 150 (No. 24256)

The Proxxon Step Clamp Set (No. 24256) is a pair of steel step clamp assemblies for securing workpieces to the MICROMOT standard T-slot tables of the Proxxon MICRO Mill MF 70 (No. 37110), KT 150, and PD 230/E. Each pair consists of 2 step blocks, 2 clamps, 2 nuts, and 2 T-slot nuts sized for the MICROMOT standard T-slot (11.5 × 11 × 4mm / 29/64" × 7/16" × 5/32").

Step blocks allow the clamp to be set at multiple height increments to match the workpiece height, ensuring clamping force is applied horizontally for secure, distortion-free workholding. The smaller MICROMOT T-slot size distinguishes this set from the larger No. 24257 set (for PD 230/E and FF 230 with larger T-slots). Sold as a pair (2 complete clamp assemblies).
