The thickened design prevents snapping and bending. The hardness, toughness, wear resistance and impact resistance ensure that the bits can be used repeatedly and keep smooth, efficient drilling on all kinds of materials.

It is perfect for drilling into tiles, glass, ceramics, mirrors, planters, wood, porcelain, brick walls, marble, thin steel sheets, and more. Tip: When working with extra-hard surfaces like glass or tile, we recommend adding water and drilling at a steady speed for best performance.
