MICROMOT steel collets They 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 shank diameters.
