Key Features

• Industrial-Grade Diamond Cutting Tip: Embedded diamond particles deliver exceptional hardness, cutting effortlessly through full porcelain, ceramic, glass, marble, and granite. Produces clean, burr-free holes and offers up to 3× longer service life compared to standard drill bits — less downtime, fewer replacements.
• Non-Slip Forged Hex Shank: Cold-forged high carbon steel hex shank fits all standard electric drills securely. No slipping or wobbling during high-speed rotation, ensuring stable torque output. Installs in seconds for fast, efficient operation.
• Accurate Center-Positioning Design: The centered cutter structure features a sharp positioning tip that locks onto the target spot — even on smooth glazed tile surfaces — eliminating drift and preventing costly rework or workpiece damage.
• Wear-Resistant Blue Anti-Rust Coating: High-temperature quenched drill body is coated with an anti-corrosion blue plating that resists rust, abrasion, and moisture, keeping bits sharp and smooth even in wet construction environments.
