ALBRECHT High-performance quick-acting drill chuck NCBF type 3441

Design: Key-less and self-tightening precision design b>with safety guard.
High concentricity (based on DIN ISO 10 888) for more precise bores and longer tool life.
All wear parts are case-hardened, ground and manufactured to be compatible with each other as well as interchangeable.

Application: For use on CNC machines and machining centres.

Note: The keyless locking on the adjusting ring prevents the NCBF chuck clamping force safety device from slackening the clamping force on the chuck at abrupt machine speed reduction. The function of the self-tightening stepless action nevertheless remains effective. That way this Albrecht system maintains the maximum clamping force in each case.
