HSK100AQER25Q66 is a right-angle machining head from Mongtec Precision, a Taiwanese tooling brand headquartered in Taichung, Taiwan. It turns the spindle output through 90° so a machining centre can cut side-facing features without re-fixturing the part. The figures below are the values Mongtec publishes for this model.

Dimensioned drawings and the confirmed article number are supplied by email one-to-one once an enquiry is open, so they match your actual spindle, stop arrangement and setup.
Three things decide whether an angle head works on your machine, and none of them are visible on a spec sheet:
| 1. Spindle interface and retention stud | The taper and the pull stud must both match. A BT40 taper with the wrong retention stud thread will not clamp. |
|---|---|
| 2. Stop block or stop pin | The head has to be held against spindle torque. The stop arrangement differs between machine builders and is confirmed against your machine before quoting. |
| 3. Clearance at the cutting position | The head body must clear the part, the fixture and the machine at the actual cutting position — not only at the tool change position. |
| Model | Driving shank | Max. RPM | Chucking range | Torque | Through dia. |
|---|---|---|---|---|---|
| HSK100AQER40Q170 | HSK100A | 4000 RPM | D1-D26 | 65 Nm | D154 |
| HSK100AQER25MQ350 | HSK100A | 4500 RPM | D1-D16 | 46 Nm | — |
Every model in this catalogue is also available as a custom build. Reach, nose profile, output interface, angle, coolant routing and the stop arrangement can all be changed to suit the operation and the machine.
