Warm Note:Since the hand drill speed is too fast, please pay attention to the speed adjustment when drilling.
The larger the drill hole diameter of the hand drill, the slower the drill speed requirement.
Recommended Drill Speeds: 100-1000RPM

Precautions for use:At the beginning of drilling, the hole opener should slowly contact with the drilled object, not bump the workpiece, and the speed should be low (the larger the diameter of the hole opener, the lower the drill speed will be).
The cutting material must be fixed without movement, and should be at a 90-degree Angle with the hole saw.
When the positioning drill bit drills through, please wait a moment, then drill hole slowly.
During the cutting process, coolant should be added according to the cutting edge temperature.
During the operation, if there is any abnormality or unsatisfactory cutting, please stop working and pour out the debris before working.
Suitable for hand held electric drill, stand motor-driven drilling machine and mobile ribbon type magnetism drilling machine.
