Advantages:
Stable quality, correct aperture, neat opening, no broken edges, no vibration, small cutting resistance, increased opening speed, high wear resistance, high precision and long service life, etc.
Note: Use with professional machinery and add coolant at the same time to extend the service life
How to use:
1. Install the hole opener on a hand drill or a cordless drill.
2. Since this hole opener does not have a center drill, tilt the hole opener at 45°, slow down the drill speed, and slowly touch the glass, stone, etc.
3. Drill a hole to create a crescent groove (the crescent groove serves as a positioning function) and then start the vertical drill. (Circular swinging cuts faster)
4. Don't cut too fast during the hole opening process, and continue to add water to cool the hole opener.
