Warm tips: When using diamond tools, please pay attention to the following matters:


1. When you newly install the tool, you must try to see if the tool jumps, if it jumps, you can't work directly, you have to adjust it to not jump before you can use it. Otherwise, the tool will wear out quickly, and the carving out is not very smooth. Adjustment method: use a small wrench to change the chuck to gently knock the high-speed rotation of the tool handle until the tool is smooth. Electronic machine is strictly prohibited to knock, the adjustment method is to loosen the collet, turn the tool at an angle or extend and indent a little.
 
2. Be sure to put water cooling (similar to the hospital drip drip device), such as dry drilling, the tool head of the diamond due to overheating will be graphitized, and thus quickly worn out scrapped.

3. When drilling, avoid shaking as much as possible, because shaking will cause local damage to the tool and accelerate the damage of the whole tool.

4. Rotate the speed as high as possible. The general requirement is a line speed of not less than 10-20 meters per second.

5. Light pressure to feed, diamond tools rely on grinding to process the workpiece, excessive force, grinding powder is not easy to exclude, the tool is also easy to damage.
