Alberti manufactures in Saronno, 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 Alberti'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). Alberti distributes through a network of regional partners; distributor details are listed at albertiumberto.com/en/company/angle-heads-distribution (accessed 2026-07-09).
Both Alberti and Mongtec angle heads mount on open BT-taper machine interfaces, so switching does not require a spindle change. Mongtec's BT40QER11Q90 is a verified, in-production model; a like-for-like cost comparison against a specific Alberti 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. Alberti's published range spans the Control, Modular, P-Modular, Index, and Smart Change angle head sub-lines plus Ultraslim and High Speed products, all customisable to specific machine tapers and collet systems including BT40 and BT50 with ER-series output (albertiumberto.com/en/products, accessed 2026-07-09). Because Alberti's per-model datasheets are distributed through a full catalogue PDF rather than individual product pages, a specific Alberti part number has not yet been matched one-to-one against the BT40QER11Q90; that determination is confirmed by Mongtec engineering on request.
If a Alberti Umberto Right 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.
