Product Introduction
spring collet set, used for holding taps, drills, milling cutters, reamers and other tools, using 65Mn, high elasticity and strong support. The hollow groove of the collet is ground and the high-precision collet chuck combines the advantages of the DIN6499/ISO15488A and B standards. The inner hole has been ground for many times to reach Ra0.4, with a mirror effect.
Mainly used for high speed cutting where good radial run out error is required. Good radial runout extends tool life.
ER series collets offer some real operational advantages.
These benefits include easier tool changes, better part finish, high clamping reliability, and the ability to accommodate a wider range of tool holder sizes.
What makes er collet different? ER Collet Slots Except for the top and bottom, when the collet is tightened, the collet compresses evenly against the tool shank, which we call uniform clamping.
