Mongtec BMT55 Static Turret Tool Holders

16 BMT55 static holders across 1 double od static tool holders, 5 face static tool holders, 6 id static tool holders, 4 od static tool holders. Interface: BMT flange mount. Listed in the catalogue for Hwacheon, Hyundai WIA, Jyoti, Samsung / SMEC, Victor. Mongtec Precision is a Taiwanese brand, designed and engineered in Taichung, Taiwan.

Double OD static tool holders — 1 model

Carry two square-shank tools in one turret station. On a turret that is already full, this is how you get another tool into the cycle without giving up a station.

Face static tool holders — 5 models

Present the tool to the face of the part rather than the diameter — for facing, grooving and back-turning operations.

ID static tool holders — 6 models

Hold a round boring bar for internal turning and boring. The bore size and the reach you need decide the model.

OD static tool holders — 4 models

Hold a square-shank turning tool on the outside diameter — the workhorse station for roughing and finishing the OD.

The letters are the dimension callouts used on the Mongtec drawing for this holder family. We publish the figures so you can compare envelope and mass across the range, but we deliberately do not label each letter here — which letter is which is defined on the drawing, and the drawing is what you should be working from. Mongtec supplies the full dimensioned drawing by email once an enquiry is open.

The label is not the fit. BMT is an industry de-facto standard — it is not published by ISO or DIN. Bolt circle, key position and clamping details can differ between machine builders at the same nominal BMT55. Send the machine model and a photograph of the turret face; Mongtec engineering compares it against the actual turret drawing before anything is quoted. The check is free and takes one email.

Driven tooling for the same turret

Most turrets run a mix. Mongtec publishes 19 driven (live) tool holder article numbers for BMT55 — axial holders for face drilling and tapping, radial holders for cross work. See the BMT55 driven tool holders →

Machines with a declared BMT55 turret

Mongtec publishes tooling pages for these 14 models. Finding your machine here confirms the turret class, not the article number — that still comes from engineering.

Frequently asked

What is a static tool holder, and how is it different from a driven holder?

A static holder clamps a turning tool or boring bar rigidly in the turret — nothing rotates in the holder itself, the workpiece does the turning. A driven (live) holder takes rotary drive from the turret so a drill or end mill can turn while the spindle is stopped. Most turrets carry a mix: static holders for the turning work, driven holders for the milling, drilling and tapping.

Will a BMT55 static holder fit my machine?

BMT is an industry de-facto standard, not published by ISO or DIN. Two turrets both labelled BMT55 can differ in bolt circle and key position, so the label alone is not enough. Send the machine model and a photograph of the turret face and Mongtec engineering checks it against the actual turret drawing before quoting. That check is free.

Which machines use a BMT55 turret?

Mongtec publishes tooling pages for 14 machine models with a declared BMT55 turret. The catalogue lists these holders for Hwacheon, Hyundai WIA, Jyoti, Samsung / SMEC, Victor.

Are dimensioned drawings published here?

No. Mongtec supplies the full dimensioned drawing by email once an enquiry is open, so the drawing matches your actual machine and turret configuration.
