BT Taper to Jacobs Taper Drill Chuck Arbors
 |  |
Adapt machines with BT taper spindles to hold Jacobs taper drill chucks. These arbors are made of hardened steel to resist wear. Their shank is precision ground to the industry standard AT3 tolerance for a secure fit that minimizes runout in your machine spindle. They meet JIS standards for BT spindles to ensure compatibility. The shank has internal threads for a retention knob, so you can connect them to your machine’s drawbar system.
Strike the top of the shank to seat these arbors onto a drill chuck. To separate them, use a drill chuck removal tool.
