Product Series Features:

ER Series DIN 6499 /ISO15488-B Spring Collet
Inch/Metric Combination
.0004" TIR
Hard Touch Coated
NOTE: ER11 COLLETS SHOWN WITH .039" (1 mm) CLAMPING RANGE HAVE BEEN PHASED OUT AND REPLACED WITH .020" (0.5 mm) CLAMPING RANGE

Notes:

Hard Touch coating increases wear resistance, improves corrosion protection, prolongs the surface finish quality, and maintains longer runout accuracy.
