Product Description

Use of the 1/4″ Drill Chuck with the Straight Shaft Arbor

This chuck comes with a straight shaft arbor designed to fit in our multi-tool holders with 3/8″ mounting holes*. The straight shaft arbor will also work with our 3/8″ insert holder tool post (P/N 7600). It has a 3/8″ diameter straight shaft with a machined flat for holding in the posts. Ensure 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 orientation will assure that the arbor does not turn or move when force is exerted on the tool.

  • 5930 4-Position Gang-tooling Tool Post
  • 5931 Rear-Side Cutoff Multi-Tool Holder
  • 5932 Front-Side Multi-Tool Holder

The improper use of machine tools and their accessories can result in serious injury. Before using this tool, thoroughly read the instructions and make sure you understand its proper and safe use.
