Cobalt Tipped Drill bits are great for use on traditionally harder to drill materials, such as ceramics.

The primary reason for this is that they are able to maintain their strength and rigidity at a higher temperature than some non-cobalt tipped bits otherwise would.

In this package, you'll receive 5 bits of varying tip sizes for increased applicability and usability across a wider range of tasks.

What's more, as these Tile Drill Bits are also Diamond Impregnated, this increases the potency and strength of the bits even further. They are able to withstand harsher and more rigorous drilling conditions.
