About the 3/8″ Chuck Arbor with 3/8″ Shank

This chuck arbor was designed to mount 3/8″ drill chucks in our multi-tool holder tool posts that have a 3/8″ hole*. Make sure the flat surface on the arbor is oriented toward the top of the tool post so the 10-32 x 3/4″ SHC screw will be perpendicular to the flat. This will assure that the arbor does not turn or move when force is exerted on the tool.

Just remove the existing arbor from the chuck and replace it with P/N 11850 arbor.

  • 5931 Rear Side Cutoff Multi-Tool Holder
  • 5932 Front Side Multi-Tool Holder
