Albrecht Key-Lock Precision CNC Drill Chucks

  • New, compact design provides increased capacity and better clearance.
  • Extremely accurate – Albrecht Key-Lock Drill Chucks are the most accurate drill chucks available.
  • Unique worm/gear arrangement is similar to the Überchuck and transmits extremely high gripping force to the jaws.
  • Short length and integral shank provide exceptional rigidity.
  • Thru-coolant feature is standard on all Albrecht Key-Lock Drill Chucks.
  • Non-rotating hood – chuck is opened and closed via a hex key inserted into the side of the body.
  • Balanced to G2.5 @ 20,000 rpm for use on all CNC machines.
  • Can be operated in both clockwise and counterclockwise directions.

The key-operated worm and gear assembly generates very high grip force and ensures that the chuck can’t loosen during operation because a worm can drive a gear, but a gear cannot drive a worm.
