MICROMOT steel collets fit all handheld MICROMOT machines, excluding the engraver GG 12. One each 1.0 – 1.5 – 2.0 – 2.4 – 3.0 and 3.2mm, clamping nut and holder for storage are included. MICROMOT steel collets are hardened and thus have a high, consistent flexibility. They also maintain prolonged accuracy, even after regular use (these collets should not be compared with unhardened, four-slit collets of brass and aluminium). The triple slit collet is substantially more difficult to manufacture than the four-slit type, but offers a better load-bearing surface. This is especially important for cutters with small shaft diameters.
