What drilling speed is recommended when using the diamond tile drill bits?

We recommend the following when using these bits:

• For best results, drill bits require water lubrication.
• When starting the hole, make contact with the tile at a 45 degree angle. (Figure 2)*
• To finish the hole pivot the bit to 90 degrees. (Figure 3)*

* See attached file for visual reference.

This information is included in the packaging of the bits.
