• 【High quality tungsten carbide】This hole saw kit is made of tungsten steel and tungsten carbide, with high tensile strength. It is very hard and has excellent wear resistance, making it valuable in cutting tools, drills, and abrasives. Even in corrosive environments, it has strong corrosion resistance.
• 【Multiple application scenarios】It is easy to drill holes in walls, stones, bricks, or install pipes such as air conditioners, range hoods, and sewers. Due to the difference in hardness between stones/bricks, hole saws require more time than normal. When processing high hardness materials, please use them in flowing water to reduce the wear of the hole saw.
