Release fork for chucks
Design:
Keyless and self-clamping
with mounting shank (one-piece).
Chuck and mounting shank form
one unit.
Optimal stability and higher concentricity is achieved by compact design
(based on DIN ISO 10888).
Application:
For high endurance stress as well as precision work on drills,
drilling machines and special drilling units.
Note:
The advantage over a two-part system is the length shorter by a total of
21 mm and thus is advantageous for machines with a small working area.
Available with diamond-coated jaws on request.
