FDC vs ER Collets
ER collets are a widely used holding solution however there are drawbacks.
Many are cheaply made, they need extra seals and nuts for each size, and have low accuracy and poor runout
NT Tool’s FDC collets have a gradual taper, which generates an even gripping force along the cutting tool.
Compaired to ER collets grabbing primarily at the neck meaning weaker grip force and off center tools.
FDC-OH and FDC-C self seal with metal seal and do not require any seals or different caps to allow coolant.
ER collets are screwed in while inserted, this tilt leads to runout. FDC are pushed in give the same accurcy every time.
Less runout leads to longer tool life.

FDC-AA collapse range of 0.5mm // FDC-OH/C collapse range of 0.5 
ER 0.5mm~4.5mm =  collapse range of 0.5mm while 5.0mm and larger = 1.0mm collapse range
