Travelling centre point with 7 inserts MK1, 9-piece
Intended use
A centre punch (often also called a centre point or rolling centre punch) is one of the most important tools when working with a lathe. It is used to secure the tailstock so that long, thin and heavy workpieces can be machined safely and accurately. With its seven interchangeable inserts, this set offers you a wide range of possible applications. The outer taper is particularly suitable for centring hollow bodies such as pipes. The inner taper included in the set can also be used to centre workpieces without a centre. The five centring points enable delicate work on the workpiece. Centre punches are mainly used at higher speeds.

Description of the
The centre point has two ball bearings and therefore achieves a high concentricity of max. 0.015 mm. It can be used up to a speed of 2000 rpm. The steel centre points and cones are hardened and ground, which increases the load capacity and service life of this item. The point angle of the centre points is 60°, as is usual for centre points. The angle of the outer cone is 70°.
In contrast to fixed centre points, the tip of rotating centre points rotates with the workpiece, which prevents friction and enables higher speeds.
We can supply you with further centre punches with 7 inserts in sizes MK2 to MK4.
