Operating Instructions:
1. Do not touch strong acid and corrosive materials
2. Please keep the bit at 90/45 degrees to the surface
3. In the process of use, the drilling efficiency can be improved by slightly shaking the auxiliary chip discharge
4. It is prohibited to drill holes in materials such as concrete, toughened glass, steel, copper, aluminum, etc.
5. Pay attention to the intensity and angle of use

Warning sign:
1. When the product is used with the angle grinder, the angle grinder needs to change the chuck
2. The higher the speed of the more stable, not easy to slip, the more holes; recommended more than 2600 rpm
3. Do not recommend the use of CNC type high-precision machine hole; suggest high-power electric drill

Model:
1. In the processing of marble/granite/agate and other high-hardness drilling materials, the first consideration is high-power models, do not recommend the use of low-power drill
2. It is forbidden to press the product by force when it is processed. It is easy for the pressure to be too high, which will aggravate the friction and affect the service life of the product
