Magnum Morse Taper 3 to Jacobs Taper 3 Drill Chuck Adapter (AMT3JT3)

Eliminating spindle runout in heavy-duty drilling applications, the Magnum AMT3JT3 Adapter bridges Morse Taper 3 (MT3) machine spindles with Jacobs Taper 3 (JT3) drill chucks. This precision-ground arbor provides a high-friction, self-holding fit that ensures axial alignment and zero-slip torque transmission. The hardened steel construction is engineered to withstand the rotational forces of industrial lathes and drill presses, maintaining its dimensional integrity through repeated tool changes.

Features

• Industrial MT3 Shank - Specifically designed for large-frame manual and CNC machinery requiring a Morse Taper 3 interface.
• Precision Ground Tapers - Ensures maximum surface-to-surface contact for a secure, high-accuracy tool connection.
• Hardened Alloy Steel - Heat-treated to resist surface scoring, tang deformation, and mechanical wear.

Specifications

• Supplier Part Number: AMT3JT3
• KMS Product Code: MAG-AMT3JT3

Frequently Asked Questions

Q: How do I install a chuck onto this adapter? A: Clean both taper surfaces thoroughly, retract the chuck jaws fully, and tap the chuck onto the adapter using a brass hammer or wooden block.

Q: Will this adapter slip under heavy load? A: The precision-ground friction fit of both the Morse and Jacobs tapers ensures the adapter self-locks under rotational load, preventing slippage.
