HSK-T (DIN 69893-6) is the HSK form made for turning — it goes into the spindle of a mill-turn centre or a multi-axis lathe and takes the cutting load of a turning operation, not a milling one. Mongtec supplies three things on it: boring bar holders, square-shank tool blocks, and integral ISO turning tools that bolt straight onto the taper with no adapter in between.
| Boring bar holder | HSK40T to HSK100T, bores 6 to 50 mm |
|---|---|
| Turning tool block | Square shank, for facing, external, cut-off and combined operations |
| Integral ISO turning tool | 38 designations built directly on the HSK-T taper — one fewer joint in the loop |

Very few makers outside Japan and Europe cover HSK-T turning. If the designation you run is not in the list above, ask — the range is wider than what is shown here and specials are normal for this interface.
Body diameters (D, D1), gauge lengths (L2, L1) and the set-screw thread (G) are in the printed catalogue and are supplied with the quotation.
