Montolit FAJ10 3/8" Diamond Drill Bit - Montolit Quality. Crafted for Daily Use

The Montolit FAJ10 Diamond Drill Bit is engineered to provide dependable, high-speed drilling on some of the hardest surfaces used in today’s tile installations. Its vacuum-brazed diamond crown cuts aggressively while maintaining clean edges, allowing installers to create precise 3/8" holes without excessive pressure or heat buildup.

This bit performs exceptionally well on dense porcelain, natural stone, and polished materials—surfaces where standard carbide bits struggle or burn out quickly. The FAJ10’s balanced steel body helps reduce vibration, giving you smoother drilling and better control, even when working overhead or on vertical surfaces.

Because it can run wet or dry, the FAJ10 adapts instantly to jobsite conditions. Whether you're setting wall anchors, drilling for clips, mounting shower hardware, or installing accessories, this bit delivers the speed, life, and reliability needed for professional results day after day.
