Diamond Hole Saw Kit | 3-60mm Core Drill Bits for Tile, Glass & Granite

Achieve clean, precise holes in hard, brittle materials with the CMCP 3-60mm Diamond Coated Glass Hole Saw. This set features a durable diamond-grit coating permanently bonded to a high-strength steel core, engineered for fast cutting and extended lifespan in glass, ceramic, and stone without chipping or cracking. Features and Benefits - Diamond Coated Cutting Edge - A full layer of industrial diamond grit is electroplated to the core, providing superior abrasion resistance for faster cutting and longer tool life compared to standard segmented rims. - 3mm to 60mm Size Range - The comprehensive set covers from small pilot holes to large diameter openings, offering versatility for a wide array of plumbing, electrical, and hardware installation tasks. - High-Speed Steel Core Body - The robust HSS construction provides exceptional rigidity and heat resistance, preventing warping and maintaining precision during prolonged use with electric drills. - Universal 1/4 Inch Hex Shank - Compatible with most standard drill chucks and quick-change systems, ensuring secure attachment and easy bit changes without slippage. - Wet or Dry Drilling Capability - Can be used with water for cooling to reduce dust and extend diamond life, or dry for convenience in situations where water use is impractical. Applications - Bathroom and Kitchen Installations - Create perfect holes for faucets, shower heads, pipework, and towel bars in ceramic wall tiles, porcelain, and natural stone backsplashes. - Glass and Mirror Work - Drill clean holes for cabinet handles, mounting brackets, or decorative elements in glass tabletops, mirrors, and shower doors without splintering. - Stone and Masonry Projects - Install lighting, vents, or plumbing in granite, marble, slate, and other engineered stone countertops or tiles with professional-grade results. Note For optimal performance and longevity, use at moderate speeds with light, consistent pressure. Using water as a coolant is highly recommended to control heat, minimize dust, and preserve the diamond coating.
