A center is a part nobody thinks about until it fails, and then it costs a whole shift. Mongtec supplies the full range on Morse tapers MT2 to MT6, with a triplex bearing stack and a seal specifically made to keep coolant out — because coolant in the bearing is what kills a center long before the point wears.

| Runout, live center | Max 0.003 mm |
|---|---|
| Runout, dead center | Max 0.002 mm |
| Shaft hardness | HRC 58–62 |
| Carbide point hardness | HRA 90–91 |
| Bearings | Triplex bearing structure |
| Sealing | Special oil seal against coolant and debris; contactless seal on some models |
| Two-level angular point | Reduces interference between the tool and the center |
|---|---|
| Three-level angular point | Less interference again, for tight tool clearance |
| Nut type | The point is replaceable — change the point, not the whole center |
| Carbide point | HRA 90–91 for abrasive or long-run work |
| Hardened steel point | HRC 58–62 general purpose |
Pipe centers carry tube and pipe on the outside diameter rather than a center hole, with an 80 degree point and a nut for adjusting head accuracy.
MT3 – MT6, workpiece ø59 to ø200 mm, 80° point
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.
