• Advanced 4-Cutter (Cross-Tip) Geometry: Features a specialized 4-flute design that ensures precise centering, prevents walking or slipping, and minimizes the risk of cracking delicate surfaces.
• Optimized High-Performance Flutes: Engineered flute geometry rapidly evacuates dust and fine debris out of the hole, significantly reducing frictional heat build-up and extending bit lifespan.
• Full Range Tool Compatibility: Standard 6.35 mm hex shank ensures fast tool changes and high-torque power transmission without slipping, perfectly matching standard drills and impact drivers on the market.

IV. Material Application Guide

• Glass, Tile, Ceramic & Stone Surfaces: Select this Hex Shank 4-Cutter Tungsten Carbide Glass & Tile Drill Bit for precise penetration, balancing high efficiency with flawless hole quality.
• High-PSI Structural Concrete / Red Brick Walls: For heavy-duty structural concrete or masonry drilling, we recommend checking out our dedicated "Professional Hex Shank Masonry Drill Bit" series in the store.

V. Usage & Maintenance Guide

• [Proper Usage]
• Verify Installation: Ensure your drill or impact driver chuck has fully locked and secured the hex shank into position before operation.
• Vertical Pressure: Keep the tool strictly perpendicular (90°) to the working surface and maintain steady forward pressure. Avoid excessive side pressure to prevent bit breakage.
• Cooling & Lubrication: When drilling glass or high-hardness tiles, it is recommended to apply water periodically for cooling and lubrication to prevent premature carbide tip wear caused by overheating.
• Speed Control: Use medium-to-low speeds with a steady feed rate to ensure optimal hole quality and safety.
• [Daily Maintenance]
• Clear Residue: Clean off all dust and debris from the bit surface and spiral flutes immediately after each use.
• Rust Prevention: As this product is made of metal, we recommend applying a thin layer of anti-rust oil after cleaning and storing it in a dry area to extend its service life.
