1. New tools must be installed when the tool is to try whether the beating, beating, then can not directly work, to adjust to not jump to use. Otherwise the tool soon wear off, carved out of things is not very smooth Adjustment method: with a small wrench chuck gently tapping the high-speed rotation of the tool handle until the tool is smooth. Electronic machine is strictly prohibited to beat, adjust the method is to release the chuck, the tool turned an angle or out and indent a little.
2. Be sure to drain the water (like a drip device like a drip in a hospital), such as a dry drill, the diamond on the head of the tool is graphitized by overheating, and it is quickly worn out.
3. When drilling, try to avoid shaking, because the shaking will cause local damage to the tool, and accelerate the damage to the entire tool.
4. The speed is as high as possible. General requirements line speed of not less than 10-20 m per second.
5. Light pressure into the diamond tool is to rely on grinding to process the workpiece, excessive force, grinding is not easy to exclude, tools (especially small tools) are also easy to damage.
