Tips
Processing hardwood or other hard materials should be injected with water to improve the quality and accuracy of drilling, and extend the life of the hole opener.
The tool edge and tip should be sharpened in time if they are worn or damaged, or the tool will be damaged quickly. Can not drill metal and non-ferrous metal, otherwise the hole opener will be damaged quickly.
The cutting material must be fixed, and the drill bit should be perpendicular to the material. It will damage the tool or the material if the cutting material moves during the drilling process.
