"Needle D's 3.0" for Angle Grinders - The new standard for hole bit performance. 

Unleash the power of our Diamond Hole Bits, meticulously engineered for rapid hole creation and extraordinary lifespan. These 8mm (5/16") hexagonal bits, featuring a 5/16" shank, are constructed from sturdy, solid steel. They are the epitome of seamless hole-making prowess. Witness these bits' longevity, precision in cutting smaller holes, and absolute integrity.


High-speed hole-making and a long lifespan. 

Experience Vacuum-Brazed Diamond Technology in action: our bits are fortified with high-strength diamonds that make tile drilling a breeze. This technology shines particularly when drilling pristine holes through robust materials such as porcelain floors, granite ceramics, glass mirrors, marble stone masonry, and bricks.

Great for various applications: from custom shower pans and shower bases to shower walls, towel bars, and toilet paper hangers.
