[Method of application]
1．Installation method：
• Weldon shank （1）：The handle of two planes aim at the two screw holes
on the drill spindle，With a hex wrench to tighten and leaving a gap of
0.2-0.3mm, Back and forth with your hand to confirm socket head screw
perpendicular to the two planes, then screw down the screws.
• Universal shank（2）: The handle of two planes aim at steel ball within the
drill chuck, then loaded into chuck.
Universal shank can also be used socket head screws，As long as socket
head screw perpendicular to the two planes.
• Fein shank（3）: Turn on insurance ring of the main shaft clockwise to the
right way, let the handle end insert into directly, rotate in small range until
steel ball enter into the hole.

3. Feed speed: The recommended feed speed is 0.08-0.12mm/R or
0.6-1.0mm/sec.Different feed speed will cause different chip and affect the
performance of removal of chips.
4. Positioning: Chisel a positioning point in the center of the position to be
drilled or mark a "cross" line with an alloy needle to ensure the accuracy of
the drilled position. Note that when using the center chisel to hit the
positioning point, please make sure that the center chisel is perpendicular
to the surface of the workpiece to avoid affecting the smooth discharge of
the cutting core
5. Start to drill: Make sure the button of magnetic drill machine is clean
before power on. Turn on the switch of coolant liquid when start to drill.
First feed slowly and feed in the normal speed after drill 1-2mm.
6. Finish drill: Turn off the power and use hook to remove the chips on the
cutter after it stops.
[Notice]
The following actions will help to reduce or slow wearing and fracturing of
cutter.
1. When drilling steel parts, please make sure enough amount of cooling
and use metal cutting fluid.
2. Good rigidity of drill pipe and the guide rail gap can improve the
precision of drilling and the life of the bit.
3. Please make sure flat and clean between the magnetic holder and
artifacts.
4. Before cutting, make sure all parts to be locked surely.

5. Drillling in the start and at the end, the drilling feed should reduce 1/3.
6. For a large amount of fine powder material which occurs in the drilling,
such as cast iron, cast copper, etc., can use compressed air instead of
coolant liquid to help chip removal.
7. Please remove the chips on the cutter, to ensure smooth chip removal.
[The solutions of common problem]
The solutions of chip core stuck:
Use nonmetallic material lightly slaping drill, or lightly pressure core
material repeatedly,in order to make it loose to pop up, also can remove
the bit, tap the thimble, so that it is out.
The wearing of tools:
Under the normal cooling, when chip appear blue-black color, it need to
check the drill bit blade, when the most big wear width is 0.5 mm, it needs
grinding.
