NUTKIT 3PCS Porcelain Tile Drill Bits, Diamond Drill Bit 6mm 8mm 10mm

• 【SIZE AND SPECIFICATIONS】This 3-piece set contains drill bits with diameters of 6/8/10 mm, a diamond height of 10 mm, and a total length of 61 mm. It is specifically designed for angle grinders with M14 threaded spindles. (Recommended power: 500W–2000W; approximately 600W is sufficient for household use). For use with electric drills or other tools, use SDS Plus, hexagonal, or round shank adapters, and ensure all impact or hammering modes are turned off.
• 【HIGH-QUALITY DIAMOND DRILL BITS】Utilizing advanced vacuum welding technology, this diamond drill bit is self-cooling, self-sharpening, and highly wear-resistant. It drills easily and is less prone to breakage and deformation, effectively reducing cracks or chipping and ensuring a superior surface finish. The combination of diamond particles and a high-hardness steel core body contributes to improved drilling efficiency and durability.
• 【BUILT-IN COOLANT】This M14 shank diamond drill bit features an integrated thermoplastic cooling wax that melts during drilling, providing lubrication and cooling, reducing the risk of overheating, effectively attracting dust, and improving drilling smoothness. Suitable for both dry and wet drilling; wet drilling extends service life.
• 【WIDE APPLICATIONS】NUTKIT diamond drill bits are suitable for drilling hard materials such as ceramics, granite, marble, glass, masonry, bricks, and quartzite. Suitable for various construction scenarios including home plumbing and electrical work, kitchen and bathroom renovations, and stone processing. Note: Not suitable for cement, metal, tempered glass, wood, or plastic.
• 【INSTRUCTIONS FOR USE】When using the drill, first drill at a 45-degree angle to the material to create a crescent-shaped cut, then drill vertically. During drilling, it is recommended to allow a short cooling break of more than 30 seconds. (Note: Do not insert the drill bit vertically to avoid overheating and damaging the tool and material.)

NUTKIT Porcelain Tile Drill Bits - for M14 Angle Grinders,Tile, Glass, Marble --Rugged steel core body improves efficiency and prevents deformation. --High-quality vacuum-brazed diamond technology provides superior temperature and abrasion resistance. Service life is significantly longer than electroplating (typically 3-5 times longer). --Cooling wax-filled drill core dissipates heat during drilling, achieving perfect cooling and extending drill bit life. --Suitable for angle grinders with all M14 thread spindles, ideal for installing fixtures, pipes, or conduits through tile and stone surfaces. Material: Diamond particles + Vacuum brazed process + Core steel body Color: As shown Drill bit size: 6mm/8mm/10mm Package contents: 3 * Storage rack box 3 * Hole opener Precautions: 1. Keep away from fire. 2. Never insert the drill bit vertically, as this will cause the drill bit to overheat and damage the tool and materials. 3. Wet operation is recommended to extend the lifespan, but precautions must be taken to prevent electric shock. 4. When using, please wear safety goggles, a dust mask, and protective gloves to ensure safe operation. If you have any questions, please feel free to contact us.
