6-120mm Marble Hole Opener Tools Diamond Hole Saw
Product Introduction
HEYIDA diamond core drill bit is a high-efficiency drilling tool specially designed for hard and brittle materials such as marble, granite, brick, ceramic, concrete and stone. Its high-strength diamond coating ensures stable cutting performance, which can quickly and accurately drill complete round holes without chipping or cracking the material surface, making it an ideal choice for professional decoration teams, construction workers and DIY enthusiasts engaged in tiling and masonry projects.
Product Features
100% Brand-New & High-Quality Craftsmanship: Adopt strict production standards and quality inspection procedures to ensure that each drill bit is free from defects, with strong wear resistance and long service life.
Diamond Coating for Efficient Drilling: The diamond-coated cutting edge has super hardness and cutting ability, which can easily penetrate various hard materials such as glass, tiles, marble and granite. During the drilling process, only water is needed for lubrication, which is environmentally friendly and easy to operate.
Lubrication Must Be Used During Operation: It is strictly prohibited to drill dry. Water lubrication can effectively reduce the temperature of the drill bit, prevent the diamond coating from burning due to overheating, and at the same time reduce dust and extend the service life of the tool.
Wide Compatibility with Common Drills: Can be connected with standard electric drills on the market, no need to configure special drilling equipment, which greatly reduces the use threshold and equipment cost.
Humanized Drilling Operation Guide: When starting drilling, it is recommended to tilt the drill bit at an angle to make a circular trace on the material surface to fix the position, and then hold the drill straight for vertical drilling, which can effectively prevent the drill bit from slipping and ensure the accuracy of the hole position.
