ER-Collet with cooling channels ER25 | 430ECC | < 15µm | Ø 7Application: For mounting straight shank tools in collet chucks DIN 6499. Note: Only nominal size d can be clamped, with cooling channels. In order to achieve an optimum sealing the tool must be clamped on the complete length of the ground drill of the collet. (applicable up to 21 bar)

parallelism: 0

Mainly for external machining

The steel body is hardened and grinded

ISO-Metric Thread

360° graduations for angular adjustment

Setting rings

5 with h4-tolerance and Ø 6 - Ø 32 with h6-tolerance

with IC DIN 6499 B (ISO 15488 B)ER-system

contact- and hot air shrink units

Automatic On/Off to maximize battery life

which can cause high frictional forces on the thread flanks

For cleaning internal tapers on machine spindles
