Drill chuck or collet?
Drill chucks provide more convenience to quickly
change the tools when working with shafts of
varying diameters. However, because of their technical
setup, they have a few drawbacks compared
to collets: Less clamping force and higher concentricity
tolerances. If high precision is necessary,
then working with MICROMOT steel collets is a
must. See also note to the left.
MICROMOT Steel Collet Set
Triple slit and hardened. 1 each of 1 - 1.5 - 2 - 2.4 - 3 and 3.2mm (1/32" - 1/16" - 5 /64" - 3/32" - 7/64" - 1/8"). With clamping nut and holder for storage.
Note:
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.
