Drilling with twist drills
MAB 525
In order to protect the tool, the maximum torque of the machine
can be set using the controller (32).
When the maximum set torque is reached, the machine switches
off. After the cut-out, the machine must be switched off and then
on again at the ON/OFF switch (21).
CAUTION
►
Do not use this function to switch off the machine when cut-
ting threads in pocket holes.
Proceed as follows when drilling with twist drills:
Push twist drills with MK taper from below into the morse
taper (3) of the machine.
Push twist drills with straight shank into the drill chuck after
fitting the drill chuck (H).
Position the machine at the working location, align it and
switch on the magnetic clamps.
Select the appropriate speed and switch on the machine.
NOTE
Observe the following instructions when drilling with twist drills:
►
Under high pressure, the drill can glow out and the machine
can be overloaded.
►
When working overhead, use the high-performance grease
spray ZHS 400. Spray the drill with grease spray before drill-
ing. Repeat the procedure when drilling deep holes.
►
Pay attention to a regular chip discharge. With larger drilling
depths, break the chip.
