Sharpening of drills for sheet metal, wood and milling cutters

For this type of drill we recommend the use of profiled grinding wheels.
Remove the clamp from the holder and position it on the adjustment line of the drill carriage.

The   adjustment   of   the   drill   bit   is   identical   to   that   of   conventional   twist   drills.   The   fine
adjustment  of   the   drill   bit  to   the   grinding  wheel   is   carried  out  by   means   of   the  screws

(Positions 7 and 9 on page 7). 
Do not start the grinding wheel motor until the adjustment is completed. In the case of

milling cutters the prism is fixed with the knurled screw in the lower position, fixed on the
side of the prism holder (Position 5 page 7). 

By moving forward with the vernier, we sharpen one cut and by turning the tool
holder a half turn we can sharpen the second cut. For tools with 3 or 4 cutting

edges we need the magnetic brake (optional)
