Grinding the drills
A new grinding geometry has been developed for drills that are used for drilling into
steel profiles. This geometry of the drill makes that all advantages mentioned above
are realized.
The main points of the grinding are:
-
The grinding of the top with an angle of app. 10°
-
The taking out or grinding away of the web of the drill
This can be done by the user provided that a suitable grinding machine is available;
good results are achieved with a KALTENBACH grinding machine type BSG 60.
