• 【Professional-Grade Vacuum Brazed Construction for Superior Durability】Experience unparalleled cutting performance with our diamond hole saw kit. Each hole saw features premium high-carbon steel with industrial-grade 35/40 diamond particles, permanently fused using advanced vacuum brazed technology. This ensures faster, cleaner cuts through hard materials while providing exceptional longevity. The hollow-body design with wide chip removal slots rapidly clears debris and dissipates heat, preventing bit burnout and protecting your valuable tiles from cracking during drilling.
• 【Complete 15-Piece Master Kit for Every Tile Project】This comprehensive hole saw kit includes everything you need for professional installations: 9PCS Diamond Hole Saws (6mm/1/4"x2, 8mm/5/16", 20mmy/4/5", 25mm/1", 35mm/1-3/8", 51mm/2", 76mm/3", 102m/4"), plus 1PC 4/5" Finger Milling Bit for enlarging holes, 1PC 2" Beveling Chamfer Bit for edge finishing, 2 Universal Adapters (5/8-11 to Hex & SDS Plus Shank), and 2PCS 5" Diamond Grinding Wheels. Unlike standard sets, our two extra grinding wheels provide immediate value for surface smoothing and tile adjustments right out of the box.
• 【Enlarge, Shape, and Finish with Specialized Diamond Tools】Go beyond simple drilling with our versatile tile saw accessories. Use the Finger Milling Bit to expertly enlarge existing holes, clean up rough cuts, or repair damaged edges. Achieve professional-grade finishes with the Beveling Chamfer Bit to create smooth, rounded, or angled edges on countertops and backsplashes. The included diamond grinding wheels let you refine surfaces and make precise adjustments—allowing you to achieve flawless results on every installation without additional tool purchases.
• 【Universal Compatibility with All Common Drilling Machines】Engineered for maximum versatility, this diamond hole saw kit works seamlessly with standard angle grinders featuring 5/8"-11 thread, or attach to drills and rotary hammers using the included Hex and SDS Plus adapters. For optimal performance: Diameter <100mm (4"): Recommended speed 6000RPM (Max 11000RPM). Diameter ≥100mm (4"): Recommended speed 3000RPM (Max 6000RPM). Suitable for both dry and wet drilling—wet drilling extends tool life and reduces debris.
• 【Conquer Any Hard Surface—From Porcelain to Granite】Engineered for the toughest materials, this hole saw kit effortlessly cuts through porcelain tile, granite, ceramic, marble, stone, and quartz. Perfect for bathroom remodels, kitchen backsplashes, faucet installations, and electrical projects. The 4 largest cores (2", 3", 4") feature maximum speed limits of 6000RPM for safe, controlled drilling. Pro tip: Start drilling at a 45° angle until the hole appears, then straighten to vertical, keeping the surface wet for heat dissipation and extended working life. For drill machine use, simply attach the included adapter (avoid hammer mode, maintain minimum 2000RPM).
