| Spec | Madaula CA-0C Angle Head | Mongtec BT30-QER11 Angle Head | Compatibility Level |
|---|---|---|---|
| Output/collet | ER-11 / φ7mm capacity | ER11 collet (per QER11 designation) | Direct collet-family match; confirm exact collet range with both suppliers |
| Input shank/taper | Not specified on Madaula's category listing; shank option (BT/CAT/HSK/ISO) is configured per the model's downloadable spec sheet | BT30 | Gap – must confirm Madaula's exact shank option against BT30 before treating as interchangeable |
| Max rotational speed | 4,000 rpm | Per Mongtec spec sheet; confirm against specific spindle rpm at quote stage | Comparable class for general milling/drilling; verify exact rpm rating for the size ordered |
| Torque | 4 (unit not specified on category page; likely Nm per Madaula's standard catalog convention) | Not a standard published figure for the QER11 line; contact Mongtec engineering | Gap – confirm units and figure directly with each supplier before use in a torque-critical application |
| Power | 1 kW | Per Mongtec spec sheet | Comparable general-purpose milling/drilling class |
| Weight | 3.5 kg | Per Mongtec spec sheet | Comparable size class |
| Ratio | 1:1 | Per Mongtec spec sheet | Comparable |

Send the Madaula CA-Series 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.
Madaula manufactures in Barcelona, Spain and supports customers through distributors and subsidiaries across Europe and other regions, which for buyers outside the EU typically means longer freight and customs transit compared to sourcing from Taiwan. Mongtec is a Taiwanese tooling brand supplying BT-interface angle heads and BMT/VDI driven tools directly, which can shorten quote-to-ship time for shops open to a functionally equivalent interface rather than an exact Madaula part number.
Madaula describes itself as having "over 65 years of experience" designing and manufacturing heads for the machine tool industry, headquartered in Sant Fost de Campsentelles, Barcelona, with a presence at major international trade shows including BIMU (Milan), SIMODEC (France), INNOTEQ (Switzerland), and EXPOMAFE (Brazil) (source: https://madaula.com/, accessed 2026-07-10). Madaula's public site does not list a specific employee count. Mongtec supports customers directly from Taiwan with engineering-verified spec sheets and quote turnaround for shops that need cross-reference support without navigating a multi-tier European distributor network.
Madaula's CA-Series spans a wide range of sizes up to CA-3 (ISO-40, 20kW, 130 Nm torque class), reflecting its focus on heavy-duty and special/custom angle-head engineering for automotive and general industrial machining. Mongtec's BT30-QER11 targets the smaller, high-volume end of the same category at a lower landed cost for job shops that don't need Madaula's full custom-engineering catalog.
Mongtec's BT30-QER11 dimensions are drawn from Mongtec's internal engineering spec sheet, verified against the published product page at https://www.mongtec-tools.com/en-US/p296-bt30qer11 (accessed 2026-07-10). Madaula's CA-0C figures (ER-11/7mm output, 4,000 rpm max, 1 kW power, 3.5 kg weight, 1:1 ratio, torque figure "4") come directly from Madaula's CA-Series product category page (accessed 2026-07-10); Madaula's page does not state the input shank/taper for this model on the category listing itself, so shops verifying an exact swap should request the model's individual PDF spec sheet (linked from the category page) and compare shank dimensions against Mongtec's BT30 spec before ordering.
If a Madaula CA-Series 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.
