Product details
MT ER holders combine a Morse taper machine connection with a selected ER collet size. The catalog lists MT2, MT3 and MT4 versions, with drawbar threads stated for each group. Choose the Morse taper and thread together, then check the available ER combination and length against the machine and tool-access requirements.
Specified drawbar threads
The table identifies M10x1.5, M12x1.75 or M16x2 by model group.
ER and reach choices
Use the listed combination instead of assuming every ER size is offered on every taper.
Specifications & model range
Dimensions are in millimeters unless otherwise stated. Confirm the final drawing before ordering.

Models and specificationsCan I use this holder without checking the drawbar?
No. The catalog lists drawbar-threaded versions; confirm the machine's retention arrangement.
Are MT2 and MT3 offered with identical ER choices?
No. Use the specific combinations listed in the table.
Does M12 alone identify the MT3 thread?
The supplied table states M12x1.75. Include the pitch when confirming the connection.
Is a drill-press socket automatically suitable for milling with this holder?
No. A matching taper alone does not approve the machine, retention arrangement or operation. Review the complete setup.
