Product Features:
- The UNIQ® DReaM Chuck, 4.5° is optimized for friction and drilling applications as well as for use with finishing cutters. It enables maximum rigidity with minimal material use with minimal interference contour due to the clamping initiation in the HSK collar. The outer contour of the UNIQ DReaM Chuck is based one-to-one on DIN 69882-8 for heat shrink chucks. As a result, the advantages of hydraulic expansion clamping technology can be transferred to these applications.

Background Information:
The BT system utilizes a proven "fast taper" (7:24) self-releasing format and is common among non-European machine tools. Note that ISO, CAT, BT, and SK are NOT interchangeable even though they use the same basic taper!.
