Diamond Hole Saw Set | 4mm-120mm Sintered Core Bits for Tile, Marble & Glass

Achieve clean, precise holes in hard materials with this 4mm-120mm diamond powder sintered drill bit. Engineered for professional results, its sintered diamond grit provides superior cutting speed and longevity compared to electroplated bits, ensuring efficient drilling through tile, marble, and glass with minimal chipping. Features and Benefits - Sintered Diamond Powder Grit - Diamond particles are bonded into a metal matrix for exceptional durability and sustained sharpness, outlasting standard electroplated bits. - Full Size Range (4mm-120mm) - A single bit covers a vast spectrum of hole diameters, making it a versatile core component for any project requiring holes from small to very large. - High-Speed Steel Core Body - Provides the necessary rigidity and strength to withstand the torque and pressure of drilling hard, abrasive materials without bending or breaking. - Precision Engineered Cutting Edge - Designed for fast, clean entry and reduced walking on smooth surfaces, saving time and improving accuracy on every job. - Universal 1/4-inch Hex Shank - Ensures a secure, quick-connect fit in most standard drill chucks and power tool adapters for immediate compatibility. Applications - Tile and Stone Installation - Create perfect holes for plumbing fixtures, outlet boxes, and pipework in ceramic, porcelain, and natural stone tiles. - Glass and Mirror Work - Drill clean holes in glass sheets, mirrors, and glass tabletops for mounting or custom fabrication with controlled, low-risk results. - Masonry and Concrete Drilling - Effectively bore into tough materials like marble, granite slabs, and engineered stone for anchoring or ventilation purposes. - Craft and Hobby Projects - Ideal for precision work on jade, ceramics, pottery, and other brittle materials where a clean, controlled hole is critical. Note For optimal performance and bit life, use with water for cooling and lubrication. Apply steady, moderate pressure and avoid excessive force or high RPMs to prevent overheating.
