VERSATILE 6-PIECE SIZE SET This masonry drill bit set includes 6 essential sizes to cover all your drilling needs: 4mm (5/32 inch), 5mm (3/16 inch), 6mm (1/4 inch), 8mm (5/16 inch), 10mm (3/8 inch), and 12mm (1/2 inch). Perfect for both small DIY tasks and larger renovation projects.
INDUSTRIAL-GRADE CARBIDE TIP Featuring high-strength carbide tips with exceptional wear, impact, and rust resistance, these bits deliver long-lasting sharpness and burr-free performance. The 4-flute serrated eccentric design penetrates hard materials (concrete, brick, polished stone) efficiently—no surface damage.
EFFICIENT SERRATED EDGE & DUST-CLEARING DESIGN Alternating serrated teeth reduce heat buildup during dry drilling, while deep U-shaped spiral flutes quickly remove chips and dust. The double U-groove structure minimizes vibration, ensuring clean, precise cuts on delicate materials like ceramic tile and glass.
UNIVERSAL COMPATIBILITY & SECURE GRIP Works seamlessly with most power drills, hand drills, and bench drills. The hexagonal anti-slip shank locks tightly in drill chucks—no slipping during high-torque drilling, even on rough surfaces like brick walls.
MULTI-MATERIAL APPLICATION Ideal for dry drilling on a wide range of materials: full ceramic tile, glass, marble, concrete, wood, travertine, hard plastic, and more. A must-have tool for home DIYers, contractors, and renovation professionals.
