Product description Key benefits Precise drilling in brittle surfaces: Designed specifically for accurate holes in glass tiles and ceramic, minimizing chipping and cracking. Durable, hard construction: Hardened hexagonal drills deliver consistent cutting performance and longer life under repeated use. Versatile size range: Includes drills that cover common hole sizes from 6 mm to 12 mm for a variety of tile work. Clear task fit: Eccentric hexagonal drills and triangular ceramic drills address different drilling needs so you can match tool to material and application. Features Set contents: Four hexagonal drills with an eccentric design and hardened construction. Also includes ceramic drills with triangular-shaped tips. Size range: 6–12 mm diameters included to cover typical tile drilling requirements. Material application: Made for precision work on glass tiles and ceramic surfaces. Purpose-built design: Eccentric hexagonal drills for specific drilling behavior and triangular ceramic drills for cutting in ceramic materials. How it solves common problems Reduces breakage: Hardened, purpose-shaped tips concentrate cutting action and reduce stress on surrounding tile to lower the chance of cracks. Improves hole quality: Precision tips and correct geometries produce cleaner holes and more reliable fits for anchors, fittings, and fixtures. Matches material and task: Separate drill shapes for glass and ceramic let you choose the best tool for the surface, improving speed and finish. Specifications (concise) Drill types: 4 hexagonal drills (eccentric, hardened); additional ceramic drills (triangular shape). Diameter range: 6 mm to 12 mm. Intended materials: Glass tiles and ceramic. Practical use scenarios Bathroom tile installation: Drill precise holes in glazed ceramic tiles for mounting towel bars, soap dishes, or grab bars without chipping the glaze. Glass-tile backsplashes: Create accurate holes through glass tile for low-profile hardware or mounting clips where clean edges are required. Repair and retrofit work: Enlarge or create new anchor holes in ceramic or glass-tiled surfaces during appliance replacement or fixture upgrades. Usage notes Select the drill shape that matches the material: hexagonal/eccentric types for the specified glass tile tasks, triangular ceramic drills for ceramic tile. Use appropriate drilling speed, support, and cooling as required for glass and ceramic materials to maximize tool life and hole quality. This set is intended for the specific drilling tasks and materials described and provides hardened, purpose-shaped drills in sizes from 6 to 12 mm to meet common precision tile-drilling needs.
