5-piece Diamond Tile Drill Set — precision, durability, and fast bit changes for hard surfaces What’s included 4 quick-install hex-shank diamond drill bits: 6mm, 6mm, 8mm, 10mm 6mm bits: diameter 6mm, total length 68mm, diamond height 10mm 8mm and 10mm bits: diameters 8mm and 10mm, total length 80mm, diamond height 10mm 1 carbide triangular pilot bit: 6mm diameter, total length 77mm (for positioning only; not for drilling) Key benefits — why this set solves the common problems Accurate starts: the included 6mm carbide triangular pilot bit gives a reliable index point so the diamond bits won’t wander on smooth tiles or stone. Fast bit changes: hex-shank quick-install design speeds tool changes and keeps you working with minimal interruption. Long-lasting cutting surface: consistent diamond coating provides strong wear resistance on hard materials. Dry drilling capability: internal wax cooling allows many dry-drilling applications without water, reducing mess and setup time. Multiple sizes for common tasks: two 6mm bits plus 8mm and 10mm cover most anchoring and fixture holes without buying extra bits. Performance and function Designed for drilling in granite, porcelain tile, ceramic tile, marble, natural stone and masonry. Diamond cutting height 10mm on each diamond bit for consistent cutting life and cleaner edges. Carbide triangular pilot bit is strictly for locating and centering diamond bits prior to drilling; it is not intended for cutting or full-depth drilling. Practical applications Installing bathroom or kitchen fixtures: drill clean, precise holes through porcelain or ceramic tiles to mount towel bars, soap dishes, or cabinet hardware. Anchoring into stone or masonry: create pilot openings in granite or natural stone for anchors and fasteners. Plumbing and electrical passthroughs: make accurate guide holes through tile and marble for routing pipes and conduit before enlarging or coring. What to expect in use Easy setup and fast swaps thanks to the hex-shank quick-fit design. Reliable starts and reduced chipping with the carbide triangular pilot. Improved convenience when water use is impractical; wax-filled design supports many dry-drilling tasks (follow best practices for heat management and tool speed). Specifications (as supplied) Set: 5 pcs total (4 diamond bits + 1 carbide triangle pilot) Diamond bits: 6/6/8/10 mm diameters; 6mm bits total length 68mm; 8mm & 10mm bits total length 80mm; diamond height 10mm Carbide triangular pilot: 6mm diameter, total length 77mm; for positioning only (not for drilling) Surfaces: granite, porcelain tile, ceramic tile, marble, stone, masonry Notes for safe, effective use Use appropriate drill speed and light, steady pressure to extend bit life. Although wax-filled for dry drilling, intermittent cooling or low-speed operation may be needed on prolonged or heavy-duty tasks. Do not use the carbide triangular pilot for cutting; it is intended only for accurate positioning of the diamond bits.
