MICROMOT steel collets are hardened and thus have a high, consistent
flexibility.
They also maintain prolonged accuracy, even after regular use (
not to be compared with unhardened, 4-slit collets and those made of brass or aluminium). The triple slit collet, 
which is much more difficult to produce than the 4-slit type, offers a much better load-bearing surface. 
This is especially important for the centrical clamping of cutters with small shaft diameters.
