Makita D-15970 Glass Drill Bit 8x70 mm with 1/4 inch Hex Shank

The Makita D-15970 Glass Drill Bit is a precision-engineered tool designed specifically for drilling clean, accurate holes in glass and soft tile surfaces. With an 8 mm diameter and a 70 mm total length, this bit is crafted to provide stability and control during delicate drilling operations. The inclusion of a 1/4 inch hex shank ensures broad compatibility with standard power drills, impact drivers, and driver drills, allowing for quick and secure bit changes in various professional and home improvement settings.

Advantages

This drill bit features a high-quality tungsten carbide tip that maintains sharpness and durability when working with brittle materials like glass. The specialized geometry of the tip minimizes the risk of cracking or chipping the workpiece, ensuring a professional finish. Its hex shank design provides a firm grip in the chuck, preventing slippage during operation and enhancing overall drilling efficiency. The bit is optimized for precision, making it an essential component for tasks requiring exact hole placement without damaging the surrounding material.

Suitable for

• Drilling holes in glass
• Working with soft ceramic tiles
• Professional glass installation projects
• DIY home decor and craft applications

When it may not be suitable

This drill bit is not designed for use with tempered glass, as the material will shatter upon contact. It is also unsuitable for drilling through hard materials such as stone, concrete, or metal, which can cause the carbide tip to overheat or break.

Key specifications

• Diameter: 8 mm
• Total length: 70 mm
• Shank type: 1/4 inch Hex
• Material: Tungsten Carbide Tip
• Compatibility: Driver drills and 4-mode impact drivers

How to use

To achieve the best results, mark the drilling location clearly on the glass surface. Secure the workpiece firmly to prevent movement. Insert the bit into your drill and ensure it is tightened correctly. Apply light, steady pressure and maintain a low drilling speed. It is recommended to use a cooling lubricant or water to prevent the glass from overheating during the process. Always ensure the drill is set to a non-impact mode, as impact force will cause the glass to break.

What to consider before purchase

• Verify the thickness of the glass to ensure the bit length is sufficient
• Ensure your drill has a variable speed setting for better control
• Confirm that the material is not tempered glass
• Use only in non-impact drilling mode

Usage recommendations

Always wear safety goggles and gloves when drilling glass to protect against sharp shards. Keep the drilling area cool with water to extend the life of the carbide tip and ensure a clean hole.
