Revolving tailstock centre
- with small head diameter, point angle 60° - body and live centre forged, hardened and ground - live centres repeatedly regrindable - high runout accuracy due to precise roller bearings, life-time lubrication, maintenance-free - sealed against dirt and cooling water
Use: Due to the small head diameter no hindrance for supports, steel holders or turning tools
