Internal construction is very similar to Albrecht Classic Drill Chucks
Integral CATand BT shanks make these chucks shorter and more rigid than a chuck/arbor combination, resulting in:
Greater accuracy
Greater rigidity
Larger work envelope
Integral shank eliminates the possibility of a chuck slipping on its arbor
Chuck can be easily tightened and opened by hand
Extra tightening force can be achieved by using a spanner wrench (included), although this chuck also incorporates the same self-tightening feature as the classic models.
Balanced to 6,500 rpm; high-speed balancing (up to 30, 000 rpm) available upon application
