Send the REGO-FIX BT-Taper 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.
REGO-FIX manufactures Swiss-made products at its Tenniken, Switzerland headquarters. Mongtec ships from Taiwan and quotes lead time per order after reviewing the specific spindle interface and any customization — there is no single published lead-time figure to compare against REGO-FIX's at this time. Request a cross-reference quote below for a project-specific lead time.
Mongtec is Taiwan-based, with an engineering-verified BT40 angle head line documented on mongtec-tools.com (accessed 2026-07-09). REGO-FIX operates a dedicated U.S. headquarters in Whitestown, Indiana, alongside its Swiss headquarters, with 280+ employees worldwide (rego-fix.com, accessed 2026-07-09).
Because REGO-FIX's BT40 collet chucks and Mongtec's BT40QER11Q90 angle head serve different machining functions, a like-for-like cost comparison is not meaningful for this page. Shops evaluating both would typically use REGO-FIX-type collet chucks and Mongtec-type angle heads together, not as substitutes for each other.
Mongtec's BT40QER11Q90 angle head is an engineering-verified unit: BT40 shank, max 8,000 rpm, 1:1 drive ratio, CW-CW rotation, ER11 collet, D1-D7 chucking range, M5-M6 tapping capacity, 10.8 Nm torque, 5.043 kg weight (Mongtec internal engineering spec, verified 2026). REGO-FIX's BT40 ER32 collet chuck line is case hardened to 58-62 HRc, pre-balanced to G2.5 @ 22,000 rpm, with 0.25 Ra surface finish and 0.0001" T.I.R. runout (industry catalog data, accessed 2026-07-09). Both product lines share the BT40 spindle standard and the broader ER-collet family; a specific fit-and-function verification for a combined tooling setup is confirmed by Mongtec engineering on request.
If a REGO-FIX BT-Taper 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.
