Ideas to use:

1. The hole opening material must be fixed well, and form a 90-degree right angle with the hole opener.
2. Coolant should be added during the drilling process to prolong the service life.
3. At the beginning of drilling, you should slowly touch a single object, do not hit the work, and the speed should be low (the larger the diameter, the lower the speed), and pay attention to slow down when you are about to drill through.
4. Please stop working when the chip removal is not ideal, and start after cleaning.
