FAQs
What materials can this drill bit be used on?
This SupaTool 8mm drill bit is specifically designed for drilling into glass, tiles, and porcelain.
Do I need a special drill for this bit?
A standard drill with a chuck that can hold an 8mm shank is sufficient. However, a drill with variable speed control is highly recommended for optimal performance and safety.
How do I prevent the glass or tile from breaking?
Use a slow drill speed, apply steady and light pressure, and ensure consistent cooling with water or a dedicated lubricant. Avoid any sudden jolts or excessive force.
What is the purpose of the 'flute-less' design?
The flute-less straight shank is designed to provide precise control and prevent the bit from wandering on smooth surfaces, ensuring a more accurate hole placement.
How often should I use a cooling agent?
A cooling agent should be used continuously throughout the drilling process to prevent overheating of both the drill bit and the material being drilled.
Can I use this bit for general purpose drilling?
No, this bit is specialized for hard, brittle materials like glass and tile. It is not recommended for use on wood, metal, or masonry.
How do I maintain the drill bit?
Clean the bit after each use to remove debris and store it in a dry place. Applying a light lubricant before storage can help prevent corrosion.
Troubleshooting
Bit is not drilling into material
Ensure drill speed is set low and apply steady, light pressure. Verify you are using a cooling agent and the bit is sharp. Check if the material being drilled is compatible (glass, tile, porcelain).
Drilling is slow or inefficient
Increase the amount of cooling agent. Reduce drill speed slightly and allow the bit's sharpness to engage. Check for any obstructions on the tip.
Bit is overheating or smoking
Immediately stop drilling. Apply more cooling agent and allow the bit and material to cool down completely. Resume drilling at a slower speed with consistent cooling.
Material is chipping or cracking around the hole
Reduce drilling pressure and ensure consistent cooling. Start the drilling at a slight angle to create a guide mark before proceeding perpendicularly. Ensure the material is adequately supported.
Pros and Cons

- Durable tungsten carbide construction for longevity.
- Reduces the risk of cracking or damaging delicate surfaces.
Cons
- Requires specific drilling techniques (slow speed, light pressure).
- Needs a cooling agent (water or oil) to prevent overheating.
- Not suitable for general wood or metal drilling applications.
- Can be prone to breakage if excessive force is applied.
Setup, Compatibility & Care
Setup: Insert the 8mm straight shank securely into your drill chuck. Ensure the drill is set to a low speed setting. Always wear safety glasses.
Compatibility: Compatible with standard drill chucks that can accommodate an 8mm shank. Best used with drills offering variable speed control.
Care: After each use, clean the bit to remove debris. Store in a dry place to prevent rust. Reapply lubricant or coolant to the tip before storing if used extensively. Allow the bit to cool before cleaning or storing.
