Phantom ER Collets DIN 6499 B / ISO 15488 B
Phantom ER collets have been internally and externally ground and finished to an ultra fine standard, achieving a roughness < Rz 2.5. Phantom collets have a large clamping range of up to -1 mm and a hardness of HRc 45+2.
Phantom can supply the following collets for various applications.
ER standard collet
Centring accuracy < 0.015 mm
This standard collet is used for round-shank tools.
ER ultra precision collet
Centring accuracy < 0.005 mm
This collet is used when high precision is required, such as when using SC tools, drilling and milling operations and reaming.
ER rubber-sealed precision collet
Centring accuracy < 0.008 mm
Sealing up to max. 40 bar
This collet is used for round-shank tools with internal cooling. Due to the smaller clamping range, the bore of the collet needs to match the shank diameter of the tool.
ER mechanically sealed precision collet
Centring accuracy < 0.008 mm
Sealing up to max. 120 bar
This collet is used for round-shank tools with internal cooling and where a pressure higher than 40 bar is applied, e.g. gun drills.
Due to the smaller clamping range, the bore of the collet needs to match the shank diameter of the tool.
ER rubber-sealed "Coolant Jet Precision" collet
Centring accuracy < 0.008 mm
Sealing up to max. 40 bar
This collet has additional cooling channels in the collet to enable the tools to be used without internal cooling.
Due to the smaller clamping range, the bore of the collet needs to match the shank diameter of the tool.
ER tap collet
Centring accuracy < 0.008 mm
This collet is designed for use with taps. Features a square tap socket to prevent twisting in the collet.
A- Insert the collet into the collet nut, turn until the eccentric ring falls into the groove of the collet. Next, press the collet in the direction of the arrows until it clicks into the nut.
B- Insert the collet and collet nut together into the collet chuck.
Next, once the shank has been cleaned, the tool can be inserted into the collet and the nut can be tightened.
C- To dismantle the tool, loosen the nut using a spanner and the collet will be pulled out of the collet chuck by the eccentric ring. Remove the tool from the collet and completely unscrew the nut and collet from the chuck.
The collet can be removed from the nut by pressing in the direction of the arrows.
