Value Collection 222-726 Taper Drill Chuck Arbor JT33

Product Description

The VALUE COLLECTION 222-726 is a taper drill chuck arbor designed to connect a Jacobs Taper 33 (JT33) drill chuck to a straight-shank spindle or tool holder. The arbor features a 0.75-inch straight shank with a 3-inch shank length, providing a secure mechanical interface between the chuck and the machine spindle. This type of arbor is a standard component in drilling setups on drill presses, milling machines, and similar equipment. Machinists, toolroom technicians, and maintenance professionals install this part when mounting or replacing drill chucks on compatible machines.

This arbor is suited for use in machine shop, manufacturing, and industrial maintenance environments where JT33-mount drill chucks are in service. It is appropriate for both bench-top and floor-standing drill press configurations, as well as milling machine setups that accept a straight-shank arbor. The straight shank design allows it to be held in a standard collet, chuck, or Morse taper adapter depending on the spindle configuration of the host machine.

Compatibility

Designed as a direct-fit arbor for drill chucks with a JT33 Jacobs Taper mount, used with machine spindles or tool holders accepting a 0.75-inch straight shank.

Installation Notes

Installation is typically performed by a machinist or qualified maintenance technician. Power down and lock out the machine before removing or installing any chuck or arbor. Seat the JT33 taper firmly into the chuck using a mallet or arbor press to ensure full engagement before use. Inspect the taper surfaces for burrs or debris before assembly, as contamination can prevent proper seating and cause runout.
