Diamond Drill Bit Set | 8-Piece for Tile, Glass & Stone | 6-45mm Hole Saws

Engineered for precision drilling in hard, brittle materials, this 8PCS diamond coated drill bits set tackles ceramic, porcelain, glass, and stone with clean, chip-free results. The set includes eight essential sizes from 6mm to 45mm, each featuring a diamond-grit coated cutting edge for superior abrasion resistance and a longer lifespan compared to standard carbide bits. Features and Benefits - Full Diamond Coating - The entire cutting surface is coated with industrial diamond grit for maximum cutting efficiency and durability, ensuring consistent performance through tough materials. - 6-45mm Size Range - Eight precisely sized bits (6, 8, 10, 12, 14, 20, 35, 45mm) cover the most common hole requirements for plumbing, electrical, and installation projects. - Integrated Pilot Drill - Each hole saw features a built-in, replaceable tungsten carbide tip that acts as a center punch and starter drill, preventing bit walk and ensuring accurate hole placement. - Reinforced Steel Core - A high-strength steel body provides rigidity and reduces vibration, allowing for smoother operation and straighter holes in tile and stone. - Universal 1/4" Hex Shank - Compatible with standard drill chucks and most cordless drill/driver systems for quick, secure bit changes without specialized tools. Applications - Tile Installation - Create perfect holes for shower fixtures, toilet paper holders, and towel bars in ceramic, porcelain, and subway tile without cracking. - Stone Countertop Fabrication - Drill faucet and soap dispenser holes in granite, marble, or engineered quartz slabs for kitchen and bathroom remodels. - Glass and Mirror Work - Safely drill holes for mounting hardware in glass tabletops, mirrors, or glass backsplashes with a reduced risk of shattering. - General Masonry - Effectively bore into brick, concrete pavers, or terracotta pots for drainage, lighting, or anchoring purposes. Note For best results and maximum bit life, use with a variable speed drill at low RPMs (300-750 RPM) and apply light, consistent pressure. Use water as a coolant to keep the diamond coating from overheating. Always wear appropriate safety gear.
