6 mm Diamond Drill Bit for high-speed hole-making and a long lifespan. Small size, yet big precision, and ultimate control. 

 

 

The Needle D's 6mm diamond drill bit is engineered for high-precision drilling in hard, brittle materials using your impact driver or standard drill. Its fine 6mm diameter allows for intricate detail work, while the advanced diamond coating ensures clean, chip-free holes in tile, porcelain, glass, ceramics, and artificial stone. This bit features a 1/4" hex shank, making it compatible with quick-change chucks found on impact drivers and standard drills.

 

 

Problem: Creating small, accurate holes in delicate materials like tiles and mosaic can be extremely challenging. Conventional drill bits often cause chipping, cracking, or wander off-center, ruining the material and the project.

 

 

Solution: The 6mm Needle D's diamond drill bit is specifically designed to address these issues. Its sharp, diamond-coated tip, combined with the controlled power of your impact driver or drill, provides exceptional control and accuracy. The dry-cut technology minimizes heat buildup and allows for cleaner drilling.

 

 

More Information: This drill bit is perfect for intricate mosaic work, installing small fixtures, creating pilot holes, or any project requiring precise, clean 6mm holes in hard materials. Its long-lasting diamond coating ensures durability and consistent performance.

It'd be great if I could get the core out of the drill bit. Gets jammed up and I cant drill anymore holes with it.
