Carbide Drill Bit Set | 6-12mm Multi-Material Bits for Glass, Tile & Concrete

Engineered for maximum durability, these 6-12mm four-blade serrated eccentric drill bits deliver clean, precise holes in the toughest materials. The unique carbide-tipped design and aggressive serrated edges provide superior bite and faster penetration, significantly reducing drill time and bit wear compared to standard masonry bits. Features and Benefits - Four-Blade Serrated Carbide Tip - The eccentric design and serrated edges aggressively fracture hard materials for faster, smoother drilling with less pressure required. - 6-12mm Size Range - Covers the most common hole diameters needed for anchors, fasteners, and plumbing/electrical runs in various projects. - Full Carbide Construction - Provides exceptional hardness and heat resistance, offering a long service life even under demanding, high-friction conditions. - 1/4" Hex Shank - Ensures a secure, slip-free grip in all standard drill chucks and impact drivers for maximum power transfer and user safety. Applications - Tile and Glass Installation - Create clean, chip-free holes for fixtures and outlets in ceramic, porcelain, and glass tiles without specialized tools. - Masonry and Concrete Work - Ideal for installing anchors, conduit, and fasteners into brick, cinder block, and poured concrete. - Metal Fabrication and Repair - Effectively drill through sheet metal, angle iron, and other ferrous metals where standard HSS bits fail. - General Construction and DIY - A versatile, all-purpose set perfect for mixed-material projects involving wood, plastic, or composite materials alongside harder surfaces. Note For optimal performance and bit life, use with a variable speed drill at a moderate RPM and employ steady, firm pressure without forcing. A pilot dimple with a center punch is recommended for hard, smooth surfaces like glass or glazed tile.
