Diamond Core Drill Bit | 100-150mm Hole Saw for Porcelain Tile & Granite

Engineer clean, precise holes in hard materials with the BRSCHNIT Diamond Core Drill Bit. This 1-piece diamond hole saw is designed for 100-150mm diameter cuts in ceramic, granite, and porcelain tile, delivering fast, vibration-free drilling with a professional finish. Its robust construction ensures durability for repeated use, offering exceptional value for demanding projects. Features and Benefits - Full Diamond Grit Segment - Provides aggressive cutting action and extended lifespan compared to surface-coated bits, ensuring efficient material removal. - 100-150mm Diameter Range - Covers the most common large-hole requirements for plumbing and electrical installations in tile and stone. - Single-Piece Steel Body Design - Enhances structural integrity and reduces wobble for straighter, more accurate holes without cracking the workpiece. - Laser-Welded Diamond Segment - Creates a permanent, high-strength bond that withstands high torque and prevents segment loss during operation. - Universal 1/2 Inch Hex Shank - Ensures compatibility with standard drill chucks and core drill machines for versatile use. - High-Grade Steel Core - Resists bending and deformation under pressure, maintaining its shape for consistent performance hole after hole. Applications - Installing Drain Pipes and Toilet Flanges - Create perfect large-diameter holes in bathroom and kitchen floors for plumbing rough-ins. - Ventilation and Ductwork Pass-Throughs - Drill clean holes in tiled walls for exhaust fans, dryer vents, and HVAC components. - Electrical Conduit and Cable Routing - Prepare precise openings for electrical boxes, recessed lighting, and conduit in tiled surfaces. - Custom Tile and Stone Fabrication - Use for DIY or professional projects requiring large, smooth holes in countertops, backsplashes, or decorative pieces. Note For optimal results and bit longevity, use with a core drill machine or a powerful hammer drill in rotation-only mode, and employ continuous water cooling during operation.
