name: masonry bit,High hardness alloy triangular shank impact drill bit,Alloy tungsten steel drill bit,cement bit,impact drill bits,Tungsten carbide hard impact drillApplications: (impact drill, bench drill) slotting and drilling: stone (granite, marble), ceramic tile, glass (non-tempered), brick wall, cement wall, hollow brick, wood, iron plate, plasticFeatures: Sharp, strong and long lifeMaterial: Hard alloy, tungsten steel alloySKU: size: 1/8 (3mm), 5/32 (4mm), 3/16 (5mm), 1/4 (6mm), 5/16 (8mm), 3/8 (10mm), 1/2 (12mm) Total length: 70mm/75mm/85mm/120mm/150mmfunction: 1. Effort-saving drilling (drilling in concrete is smoother). 2. Compared with the single thread, the double-thread drilling is faster (the chip removal is smooth in the thread groove), and the spiral design is conducive to high-speed operation and fast chip removal to improve work efficiency. 3. High hardness, strong toughness, high temperature quenching, not easy to break. 4. The hard alloy cutter head is not easy to wear and rust, and is impact-resistant. 5. Anti-slip triangular handle, suitable for impact hand electric drills, prevents falling off, convenient and fast.
