Double Ceramic Round Chuck

Due to its high holding force and watertight top plate, the MPI Double Ceramic Round Chuck is an indispensable tool during workpiece turning and circular grinding. The relatively small pole pitch and a low magnetic field make it suitable for thinner workpieces from 0.3 in or from 0.5 in depending on the chuck diameter or pole pitch.

  • Solid silver brazed top plate with parallel poles
  • Double Ferrite magnetic system
  • Waterproof design
  • Very light aluminum body
  • Aluminum base with the possibility of mounting on a flange or into a chuck
  • Pole pitch: T13 8+5mm (steel/brass) or T17 12+5mm (steel/brass) T0.5 0.3 + 0.2 in (steel/brass) or T0.7 0.5 + 0.2“ (steel/brass)
  • Holding force up to 140N/cm² / 203lbs/in² depending on size of chuck
  • Poles transverse
  • One (1) year warranty for the magnetic system


How the Double Ceramic Round Chuck Works:

The top plate is magnetic with each pole individually magnetized by powerful ceramic permanent magnets. This makes it so electrical controls and collector rings are not required. Frequent magnet polarity changes result in low magnet field to prevent magnetization of tool bits.
