How to Use
1. When you install a new 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.
2. Be sure to put water cooling, if dry drilling, diamond due to overheating will be graphitized, thus quickly worn out scrap.
3. When drilling, try to avoid shaking, because shaking will cause local damage to the tool and accelerate the damage of the whole tool.
4. 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.
