CUTTING TOOLS

10 558 VHM thread drilling tool
the drilling must be carried out dry, at approx. 1500 - 3500 rpm. The core of
the thread is quickly drilled by using a suitable core drill and the remains of the
tap can be cleanly removed from the drill hole.
The workpiece must be very stably clamped so that it cannot move at high speeds.
If the tap broke out obliquely a centring has to be made first by driving the thread
drilling bit at it several times. Only then can the drilling begin. In addition, the
chips have to be removed by swarf clearing several times.
Before reaching the end of the drilling process you will feel vibrations. The drilling
bit should now be removed. It is now possible to cut a new thread using a tap bit.
Due to the large stresses that occur during drilling the cutting edges of the tool
must be resharpened from time to time to achieve optimum results.
