Product details
BT MTA adapters provide a BT spindle connection and a Morse taper socket for an appropriately matched tool. The catalog lists MT1 through MT5 across the complete series, with coverage depending on the BT size. Check the tool's taper and retention details as well as the adapter reach before confirming the selected combination.
Coverage by BT size
BT30, BT40 and BT50 do not share identical Morse taper coverage.
Retention and reach
Review the tool end geometry and the adapter drawing; taper size alone is insufficient.
Specifications & model range
Dimensions are in millimeters unless otherwise stated. Confirm the final drawing before ordering.

Considering existing taper-shank drills for a confirmed BT adapter assembly.
Reaming setups
Reviewing Morse taper reamer mounting, access and retention requirements.

Models and specificationsDoes BT30 cover MT5 in this series?
No. The catalog lists BT30 coverage as MT1–MT3; the complete family's coverage must not be applied to every interface.
Are MTA and MTB interchangeable?
Do not assume so. Compare socket, retention and length drawings for the actual tool and machine.
Can I use this page to approve a milling setup?
The adapter and cutter retention, clearance and machine requirements need review. The taper labels alone do not approve an application.
What is needed for an unmarked tool?
Provide measured taper details and photographs of its end geometry, together with the machine interface.
