Features

• PROFESSIONAL TILE & GLASS DRILL BIT SET: This Tile & Glass Drill Bit Set is designed for precise, clean drilling in hard materials. Featuring diamond-coated core bits from 6-12mm and an included 8mm twist drill, it delivers reliable performance for ceramic, glass, concrete, and masonry projects using standard electric drills.
• DIAMOND-COATED CORE BIT TECHNOLOGY: Each core bit is diamond-coated to enhance cutting efficiency and durability when drilling through tough surfaces. The abrasive diamond layer reduces chipping and cracking, ensuring smoother holes in tiles and glass while maintaining long-lasting sharpness even under heavy-duty use.
• HEAVY-DUTY ECCENTRIC DRILL DESIGN: The eccentric drill bit design improves stability and reduces walking during startup. This allows for more accurate positioning and controlled drilling, especially on smooth or brittle surfaces like ceramic tiles and glass, helping achieve professional results with less effort.
• VERSATILE SIZE RANGE WITH TWIST DRILL INCLUDED: The set includes core bit sizes from 6mm to 12mm, covering common installation needs such as anchors, plumbing, and fixtures. An additional 8mm twist drill bit enhances versatility, making the set suitable for both pilot drilling and core drilling tasks.
• 1/4-INCH HEX SHANK FOR WIDE COMPATIBILITY: Equipped with a standard 1/4-inch hex shank, these drill bits ensure a secure fit and reduced slippage. They are fully compatible with most electric drills and drivers, allowing quick bit changes and reliable power transfer for efficient, stable drilling performance.
