Boa Quick Change Diamond Tip Drill Bits - TK3078

These drill bits are specifically designed for hard materials such as granite, porcelain, engineered stone, concrete, and tile.

The quick change system allows for rapid and secure attachment and detachment of the drill bit from the drill chuck without the need for additional tools, saving time on job sites.

While not strictly essential for all applications, the CCV guide and water cooling system significantly enhance performance, precision, visibility, and the lifespan of the drill bit, especially when working with very hard materials or for extended periods.

Clean the bits after use, store them in a dry environment, and utilize water cooling to prevent overheating during operation. Regularly inspect the diamond tip for wear.

These bits are optimized for hard materials. While they might work on very dense woods, they are not the ideal choice and may wear prematurely or provide suboptimal results compared to standard wood drill bits.

Vacuum brazing is a high-temperature process used to bond the diamond particles to the bit's core, creating a very strong, durable, and heat-resistant bond that ensures the diamonds remain securely in place during demanding drilling.

Yes, Boa offers these drill bits in various sizes. Always refer to the specific product listing for available sizes and verify against any size guide images, as brand sizing can sometimes vary.

Ensure the drill bit is correctly seated in the quick-change chuck and that the chuck is securely tightened. Verify you are using the appropriate speed and pressure for the material. Check for excessive wear on the diamond tip.

Discontinue drilling and allow the bit to cool. Use the Boa water cooling system or an alternative method of cooling, such as intermittent water application. Reduce drilling pressure and speed.

This can indicate insufficient cooling, excessive speed, or excessive pressure. Ensure adequate water supply and consider using the Boa CCV guide for improved control. Reduce drilling pressure and ensure the material is properly supported.

Clean any debris from the chuck and the bit shank. Apply a small amount of lubricant designed for tool chucks. Ensure the bit is fully inserted and the mechanism is operated as intended.
