How to use

To achieve the best results, mark the desired drilling location clearly. Secure the glass piece firmly on a flat, stable surface to prevent vibration. Use a drill set to a low speed and apply very light, consistent pressure. It is recommended to use a coolant, such as water or a specialized drilling lubricant, to keep the bit cool and prevent the glass from overheating, which can lead to cracking.

What to consider before purchase

• Verify the thickness of the glass material
• Ensure your drill has a variable speed control
• Confirm the material is not tempered or safety glass

Usage recommendations

Always wear safety goggles and gloves when drilling glass to protect against sharp shards and dust. Ensure the drill bit is kept cool during the entire process to prolong its lifespan and protect the workpiece.
