Description
Version:
- Tool fully hardened and ground.
- Bearings designed to take high axial forces.
- Maintenance-free greased for life.
- Shaft seal prevents ingress of dirt and cooling fluids.
Description:
Lathe centres are mainly used on lathes to support long and slim workpieces, since with these workpieces there would otherwise be a risk of the workpiece bending or moving around as a result of the forces generated.
The lathe centre is secured with a Morse taper. The workpiece is clamped in the chuck and a counterbore is added using a centre drill. After re-clamping, the lathe centre is then inserted.

Application:
- Combi tool for standard centring and machining pipes.
- Perfect all-purpose tip for general use on manual and CNC machines.
