Morse Taper to Jacobs Taper Arbor and Drill Chuck Sets
 |
Everything you need to adapt your machine’s Morse taper spindle to hold round- and hex-shank drill bits. The drill chuck and arbor in these sets are separate pieces, so you can swap out a worn chuck or replace it with a keyless one without replacing the arbor. Compared to drill chucks with an integrated arbor, these sets give you more versatility but are longer, less rigid, and less accurate.

R8 Taper to Jacobs Taper Drill Chuck Arbors
 |
Adapt machines with R8 taper spindles to mount Jacobs taper drill chucks. These arbors are made of hardened steel and are precision ground for accuracy. They thread onto your machine’s drawbar for a secure connection. Strike the top of the arbor to seat them onto a drill chuck. To separate them, use a drill chuck removal tool.
Economy—Economy arbors are great for occasional or low-volume jobs.
Industrial—Industrial arbors are harder and more wear resistant than Economy arbors.

Drill Chuck Arbors with Drill-Feed Attachment
 |
Drill Chuck Not Included |
Take control when drilling small holes with a drill press, milling machine, or lathe. These arbors have an attachment that lets you gently feed the bit forward by hand while the machine rotates it. When you let go, your chuck retracts automatically.

Industrial—Industrial arbors are compatible with any JT0 taper drill chuck.
Premium—Premium arbors are crafted by Albrecht, a brand known for its unmatched quality. Made in Germany, every arbor undergoes multiple inspections and tests to ensure that they operate smoothly over their long life. They have a high-precision spring to reduce vibration and extend tool life for continuous use. These arbors are designed for Albrecht 15-J0 drill chucks but will still fit JT0 drill chucks, though performance may be reduced.

NMTB Taper to Jacobs Taper Drill Chuck Arbors
 |  |
Adapt machines with NMTB taper spindles to mount 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. Internal threads in the shank connect to your machine's drawbar. These arbors meet ASME standards for compatibility across machines with NMTB spindles. They're also compatible with older Erickson quick-change spindles.
Strike the top of the arbor to seat them onto a drill chuck. To separate them, use a drill chuck removal tool.

CAT Taper to Jacobs Taper Drill Chuck Arbors
 |  |
Adapt machines with CAT 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 ASME standards for CAT 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.
