FORSTNER DRILLS AND CUTTERS
For the above mentioned drills it is recommended to use specially dressed grind wheel
faces (Picture).
Release the clamping lever of the prism rest and place on the adjustment line of the drill
feed carriage (see picture). The adjustment of the drills is identical to twist drills. The fine
adjustment of the drill to the grinding wheel is carried out with the screws
(Pic page 5, No. 7 and 9).
Only when the setting-up work has been completed, switch on the motor and start
working ad described in the chapter "Grinding of drills". For milling cutters. the prism is
fixed with the knurled screw in the lower screw hole, placed on the side of the prism
support. (Page 5, No. 5).
By moving forward with the knurled nut, sharpen one cutter and after reversal of the
prism, sharpen the second side (Pic page 5, No. 9). For milling cutters having 3 or 4
cutting edges you will need the magnetic deph stop (option).
Forstner drills in contrary to other drills are not adjusted accourding to adjustment marks
on the prism, but aligned to the stagnant grinding wheel.
The grinding operation is same as for cutters.
