Product details
BT drill chuck arbors connect a listed BT spindle interface to a drill chuck with a Jacobs or B taper mounting socket. The two taper families are shown separately in the catalog. Match the chuck's actual socket designation and the machine's retention arrangement before choosing the arbor, even when two connections look similar.
Machine-side connection
BT size and pull-stud requirements must be checked against the machine.
Arbor versus chuck
This series is the mounting arbor; confirm the drill chuck separately in the quotation.

Models and specificationsCan I replace a B16 arbor with a JT6 arbor?
Do not substitute taper codes based on visual similarity. The arbor must match the chuck's specified socket.
Does this product include a drill chuck?
This page covers the arbor. Ask for the chuck explicitly if a complete assembly is required.
Is the listed pull-stud thread enough to approve fit?
No. Confirm the full retention component and machine requirements, not only the thread designation.
Why does one pull-stud table cell say Confirm?
The BT50-B source row is not complete for that value. It must be verified rather than inferred from adjacent rows.
