PCD valve hole drills

Reliable tool solutions

The requirements for aluminium wheel machining drills have risen steadily in recent years. The end-user of the finished wheels expects an ever increasing finish quality of the valve hole bore along with decreasing tolerance fields.

To meet these requirements, Ochel Werkzeugproduktions GmbH has been producing PCD tipped drills for the machining of aluminium wheels for many years.

Compared with solid carbide, PCD cutting material  can be used in the case of higher cutting values and it produces a better finish quality in the bore. At the same time, the contour always remains dimensionally stable from the first bore to the last. This is the main point of difference from solid carbide cutting material, which is continuously worn down by machining.

Together with our customers, we continue to develop our PCD tipped drills.

The characteristics of our PCD valve hole drills
are as follows:

- closest tolerance in the contour area ±0,005 mm
- 4 parallel IKZ bores
- shanks according to DIN 6535 or customer requirement

Sharpening service:

Of course, our PCD tipped drills can be repaired if the tool body has not been destroyed.
If the PCD shows no sign of spalling, EDM and PCD grinding are sufficient. In the event that one or more PCD inserts have been damaged, they will be renewed and the complete contour re-attached.
