Product details
BT MTB Morse taper adapters form a separate catalog series with listed BT30, BT40 and BT50 combinations and shorter L1 options than many MTA entries. Select from the exact row for the required Morse taper. Before using an existing taper-shank tool, confirm the internal connection and retention geometry on the final adapter drawing.
Specific socket combinations
BT30 lists MTB1 and MTB2; BT40 and BT50 rows extend through MTB4.
Drawing comparison
Use the actual socket and tool drawings when comparing MTB with another adapter family.
Specifications & model range
Dimensions are in millimeters unless otherwise stated. Confirm the final drawing before ordering.

Models and specificationsCan I order MTB4 in BT30 from the listed table?
That combination is not listed. The BT30 row contains MTB1 and MTB2; an unlisted request requires separate review.
Is MTB simply another name for MTA?
The catalog treats them as separate series. Confirm their actual drawings rather than merging the codes.
Does shorter L1 guarantee better machining performance?
No performance rating is stated here. Assembly stiffness, retention and the operation need individual assessment.
Can you match an existing compact adapter?
Send its complete code, measured length and clear photographs of both interfaces for confirmation.
