Quick Change Diamond Tip Drill Bits - Boa UTTK3077

These bits are specifically designed for very hard materials such as porcelain, ceramic tiles, glass, stone, granite, marble, and concrete. They are not recommended for wood or metal.

Yes, water cooling is highly recommended, and often essential, when drilling hard materials with diamond bits. It keeps the bit cool, prolongs its life, and helps to control dust.

The quick-change system allows for faster and easier swapping of drill bits in compatible chucks, saving time during multi-stage drilling tasks.

The lifespan varies greatly depending on the material being drilled, the pressure applied, and the effectiveness of cooling. However, due to the vacuum brazed diamond tip, these Boa bits offer superior endurance compared to standard bits.

No, never use diamond-tipped bits with a hammer drill function. Always ensure your drill is set to a standard rotary (non-hammer) mode.

These Boa Quick Change Diamond Tip Drill Bits are manufactured in the UK.

The Boa CCV (Cool Clear Vision) guide is an optional accessory that helps with accurate starting of holes and provides a system for water cooling, improving drilling precision and dust suppression.

Ensure the drill is not in hammer mode. Check if you are using sufficient water cooling. Increase speed slightly if possible, or try a different drilling angle. The material might be exceptionally hard; consider a larger diameter bit or a specialized diamond grinding paste if applicable.

Immediately stop drilling and allow the bit to cool. Increase the water flow significantly. Reduce drilling pressure and speed. Ensure the bit is not worn out; a dull diamond tip generates more heat.

This is uncommon with vacuum brazed bits. If it occurs, stop immediately. Excessive force, binding, or drilling into an unexpected material could be the cause. Inspect the chuck for damage and ensure the bit is properly seated.

Ensure the drill chuck is fully opened. If the bit is hot, let it cool completely before attempting removal. Some quick-change systems may require a specific release action; consult your drill's manual.
