Pumpkin ⁵⁄₁₆” Tile and Glass Bit

Pumpkin 5/16″ Tile and Glass Bit

Pumpkin 5/16″ Tile and Glass Drill Bit – ISO Certified Carbide Spear Tip for Precision Drilling in Brittle Materials

The Pumpkin 5/16″ 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 YC8C Carbide Spear Point tip (HRC 89-90 hardness), 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 ceramic and glass, providing smooth, chip-free drilling without cracking the material. The 5/16″ diameter is suited for standard wall plugs and medium-sized anchors. This product is ISO 9001:2000 certified, guaranteeing its quality and consistency for professional use.

Key Benefits

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

• High-Grade Carbide: YC8C Carbide (HRC 89-90) 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.

• Certified Quality: ISO 9001:2000 certification ensures high manufacturing standards.

• Size Suitability: 5/16″ diameter is ideal for standard wall plugs and medium-sized hardware installation.

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.
