Product DescriptionProduct DescriptionEngineered for heavy-duty stone processing, these diamond core bits feature 3.8ct/cm2 vacuum-brazed diamond coating (40/50 grit) on 65Mn steel bodies. The reinforced hex shank (22.23mm) locks securely in angle grinders (100-150mm disc size), delivering 3x faster drilling than traditional hole saws. Optimized spiral grooves dissipate heat at 5000 RPM, enabling dry cutting of 20mm-thick granite in 15 seconds. Ideal for HVAC installations, plumbing, and construction projects requiring precision holes in mixed materials.SpecificationKey Product FeaturesThis revolutionary 12-in-1 drilling system combines three breakthrough technologies:Smart Shank Adapter - Patented 3-in-1 shank (1/4" hex/5/8" thread/M14) fits 95% of global power tools.Diamond Matrix Control - 40/60/80 grit zones for glaze penetration → cutting → polishing in single pass.Thermal Armor Coating - Ceramic-reinforced steel body reduces heat transfer by 60%, enabling 8000 RPM dry drilling.Achieves 0.03mm precision on 12mm-thick porcelain tiles and 5mm tempered glass. Includes vibration-dampening guide jig for handheld stability.Specifications and DimensionsAngle Grinder Focused - 22.23mm hex shank fits 100-150mm grindersHybrid Cooling System - Laser-cut slots + air vents reduce temperature by 50%Multi-Material Mastery - Single bit drills granite (Mohs 6-7), ceramic (Mohs 8), and concrete (50MPa+)Anti-Breakage Design - 3.5mm thickened steel wall withstands 80kg lateral forceFast Debris Clearance - 45° spiral angle expels chips 2x fasterCE/GS Certified - Meets EU power tool safety standardsItem No.Diamond Grit SizeThreaded Interface5mm-150mm (Customizable)6~18mm (46#) 20mm and above (36#)M14This product is suitable for making holes in hard materials such as marble, concrete, granite slabs, and full porcelain tiles.
