Porcelain & Tile Drill Bit Set | 5-Piece M14 Thread | For Granite, Marble & Vitrified Tiles

Engineered for precision drilling in the hardest materials, this 5-piece M14 thread dry drill hole saw set delivers clean, professional results in porcelain, granite, and vitrified tiles. The specialized brazing technology on the diamond grit ensures faster cutting speeds and extended bit life, allowing you to complete installations efficiently without chipping or cracking the workpiece. Features and Benefits - M14 Universal Thread - Provides a secure, wobble-free connection with most standard drill chucks and arbors for stable, controlled drilling. - Premium Diamond Brazed Segments - The industrial-grade diamond particles are permanently bonded to the steel core, offering superior cutting speed and longevity compared to electroplated bits. - Dry Drilling Capability - Designed to operate without water cooling, making it ideal for on-site and overhead work where water use is impractical or messy. - 5-Piece Size Variety (Commonly 6-25mm) - The set covers the most frequently needed diameters for faucet, pipe, and electrical outlet installations, offering great versatility. - Reinforced Steel Body - The robust construction resists bending and deformation under high torque, ensuring straight, accurate holes every time. Applications - Bathroom and Kitchen Renovations - Install faucets, shower fixtures, and soap dispensers in porcelain, ceramic, and natural stone tiles with clean, finished holes. - Flooring and Tiling Projects - Create precise openings for toilet flanges, heating pipes, and floor drains in vitrified tiles and marble slabs. - Electrical and Plumbing Work - Drill conduit and pipe pass-throughs in granite countertops, backsplashes, and hard tile surfaces during construction or remodeling. Note For optimal performance and bit life, use a variable speed drill at a moderate RPM with steady, firm pressure. Allow the diamond grit to do the work; forcing the bit can generate excess heat.
