Send the Sandvik Coromant 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.
→ Full PSC article-number listing by coupling size: Mongtec PSC (ISO 26623) — PSC32 / PSC40 / PSC50 / PSC63 / PSC80 / PSC100 (385 published article numbers, with Capto® C3–C10 and PSK size equivalence).
Mongtec’s PSC series driven tool holders use the polygon shank coupling standardized in ISO 26623 — the same open coupling geometry implemented by Sandvik Coromant’s Capto® program. Because the polygon interface is an ISO standard, Mongtec PSC units are designed for direct interchange with Capto®-type cutting units of the corresponding polygon size on BMT and VDI turrets. Mongtec’s current PSC line covers 32 models across BMT40 / BMT45 / BMT55 / BMT60 / BMT65 and VDI turret interfaces, including axial tool heads with through coolant (Mongtec model database, Ver 2026.3). Polygon size matching for a specific Capto® cutting unit is confirmed by Mongtec engineering at RFQ.

Sandvik Coromant manufactures across a global production network, including its Gimo, Sweden tool production plant. Mongtec ships from Taiwan and quotes lead time per order after reviewing the specific turret interface, drive type, and any customization — there is no single published lead-time figure to compare against Sandvik Coromant's at this time. Request a cross-reference quote below for a project-specific lead time.
Mongtec is Taiwan-based, with a BMT/VDI driven tool line organized by machine platform (mongtec-tools.com/en-US/plist1-bmt-vdi-tool-holder, accessed 2026-07-10). Sandvik Coromant is represented in more than 150 countries with approximately 8,000 employees worldwide and operates 15 Global Coromant Centers for training and application support (sandvik.coromant.com/en-us/about-us/company-facts, accessed 2026-07-10).
Both Sandvik Coromant and Mongtec driven tools mount on open machine-side standards (VDI per DIN 69880, BMT per machine-builder spec), so switching does not require a turret change. A like-for-like cost comparison depends on the specific unit and has not been performed for this page.
Mongtec's BMT/VDI driven tool line is organized by machine platform, with runout, bearing grade, and torque/speed figures published per model on request (Mongtec internal engineering spec, verified 2026). Sandvik Coromant's published BMT85/BT85A clamping unit (item 6144288) is rated to 3,000 rpm max speed and ≈210 Nm max cutting torque, with its VDI tool holder program covering DIN 69880 sizes VDI30 through VDI80 (sandvik.coromant.com, accessed 2026-07-10). Turret interface dimensions and drive-type matching for a specific cross-reference are confirmed by Mongtec engineering before any compatibility level is assigned on this page.
If a Sandvik Coromant 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 driven tool holder 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.
