Send the O.M.G. (OMG) part number together with your machine model and turret — Mongtec engineering maps it to the matching Mongtec article number at quotation. The check is free.
O.M.G. manufactures in Cavriago, Italy. Mongtec ships from Taiwan and quotes lead time per order after reviewing the specific taper, drive type, and any customization — there is no single published lead-time figure to compare against O.M.G.'s at this time. Request a cross-reference quote below for a project-specific lead time.
Mongtec is Taiwan-based, with an angle head line built around open BT-taper interfaces and an engineering-verified BT40QER11Q90 spec sheet on file (Mongtec internal catalog, accessed 2026-07-09). O.M.G. operates through OMG North America (Post Falls, Idaho) for the US market plus a direct Italian sales operation (omgnet.it/omg-contacts, accessed 2026-07-09).
Both O.M.G. TA-series and Mongtec angle heads mount on open BT-taper (or VDI, for O.M.G.'s TA...VDI variants) machine interfaces, so switching does not require a spindle change in most cases. Mongtec's BT40QER11Q90 is a verified, in-production model; a like-for-like cost comparison against a specific O.M.G. part number has not been performed for this page.
Mongtec's BT40QER11Q90 angle head carries an engineering-confirmed specification: BT40 driving shank (additional shank types available on request), maximum 8,000 rpm, 1:1 transmission ratio, CW–CW output rotation, ER11 collet with D1–D7 chucking range and M5–M6 tapping capacity, 10.8 Nm rated torque, and 5.043 kg unit weight. O.M.G.'s TA series spans 90° single- and double-spindle heads, ±90° variable angle heads (including digital-display variants), fixed custom-angle heads, coolant-through variants up to 70 bar, and dedicated VDI-shank models (TA...VDI, TAV...VDI), engineered with heat-treated kinematics, Gleason bevel gear pairs, and a newly designed anti-rotation group rated for backlash-free operation up to 10,000 rpm (omgnet.it/prodotti-en/angle-heads-ta, accessed 2026-07-09). Because O.M.G.'s per-model datasheets require customer login, a specific O.M.G. part number has not yet been matched one-to-one against the BT40QER11Q90; that determination is confirmed by Mongtec engineering on request.
If a O.M.G. (OMG) unit on your machine is worn, damaged or discontinued, you do not need the original article number to replace it. Send the model number, the name plate photo, or the drawing of the angle head you run today — Mongtec engineering cross-references the mounting, coupling and output geometry and quotes a suitable Mongtec article, stating clearly which dimensions were confirmed. Repair of the existing unit is sometimes the better answer; where we see that, we say so.
Mongtec publishes this comparison so buyers can judge the swap themselves. It is not a claim that one brand is better than the other — the two are different companies with different ranges, and the right choice depends on the machine and the job.
Send it to info@mongtec.com or use the enquiry form. A drawing or a photo of the unit on the turret speeds this up; neither is required to start.
