About this item
- Complete 10-Piece Set with 5 Common Sizes๏ผIncludes 5 hole saws (core drills) and 5 solid drill bits. Hole saw sizes: 1/4" (6mm) x2, 5/16" (8mm), 3/8" (10mm), 1/2" (12mm). Solid drill bit sizes: 3/16" (5mm), 1/4" (6mm), 5/16" (8mm), 3/8" (10mm), 1/2" (12mm). One kit meets your needs from fine pilot holes to larger diameter drilling.
- Centering Pilot for Precise Positioning๏ผEach diamond drill bit features a centering pilot tip that locks firmly onto your marked spot, preventing slipping on smooth surfaces like glass, tile, or mirror. Guarantees a clean, accurate start and consistently precise holes in ceramic tiles and other delicate materials.
- Vacuum-Brazed Diamond Grit โ Strong & Wear-Resistant๏ผMade from high-carbon steel with premium diamond grit, bonded through an advanced vacuum brazing process. Offers exceptional hardness, excellent wear and rust resistance, and a long service life. Built to handle repetitive, heavy-duty drilling tasks.
- "Built-in Cooling Wax โ Dry & Wet Drilling Optimized: Each drill bit contains an integrated lubricating wax that melts during operation, continuously cooling the tip and preventing diamond loss. Supports both dry drilling (fast cutting) and wet drilling (maximum lifespan). Delivers high performance on porcelain, ceramic, and other hard brittle materials."
- Wide Application โ From Construction to Home Improvement:Thanks to its outstanding hardness and wear resistance, this multi-functional diamond drill bit set works effectively on concrete, brick, stone, granite, glass, ceramic tile, and masonry. Perfect for construction projects, engineering machinery applications, and DIY home renovations โ boosts your work efficiency across the board.
