Harden 12mm Tile and Glass Drill Bit

Harden 12mm Carbide Tile and Glass Drill Bit – Precision Carbide Spear Tip for Brittle Materials

The Harden 12mm Carbide Tile and Glass Drill Bit is a professional-grade tool engineered for precision and clean results when working with delicate and brittle materials. This bit features a specialized Carbide Spear Point tip, which is designed to prevent “walking” on smooth surfaces like glass, mirror, and ceramic tile, ensuring the hole starts accurately and neatly. The high-quality carbide material resists the abrasive wear from hard ceramics, providing smooth, clean drilling without chipping or cracking the material. The 12mm diameter is ideal for larger anchors, pipe penetrations, or fixture mountings in tiled surfaces.

Key Benefits

• Precise Spear Point: Specialized tip geometry minimizes bit walking and chipping on slick, brittle surfaces (tile, glass).

• High-Grade Carbide: Durable tip material maintains sharpness and integrity when drilling hard ceramic and glass.

• Clean Holes: Cuts precise, clean edges without the risk of cracking common to standard masonry bits.

• Size Suitability: 12mm diameter is ideal for larger fixtures, pipes, and electrical conduit penetration through tile.

• Professional Quality: Harden brand assurance for reliable performance in tiling and glazing.

Application Instructions

• Drilling Mode: MUST USE ROTATION-ONLY MODE; NEVER USE HAMMER/IMPACT FUNCTION.

• Lubrication: Keep the drill site cool by applying water or drilling fluid continuously (essential for glass and hard ceramic).

• Starting: Start at a low RPM with light pressure. Do not apply excessive force.

• Cooling: Lift the bit occasionally to allow water to enter the hole.

• Safety: Wear safety glasses and gloves when drilling brittle materials.

Pro Tips

• Create a template or guide (e.g., masking tape) to help start the hole and prevent the bit from walking.

• Always keep the drill bit and the hole cool with water for the longest bit life and to prevent cracking the tile.

• Do not exceed a medium drill speed; excessive speed generates heat and dulls the tip rapidly.

• Store the bit securely in its protective tube to protect the carbide tip from chipping.
