Quality tool! Low runnout, but too much wax.

Model: 3/8 Inch (10mm) Dry Diamond Core Drill BitsPerfect for creating drainage holes in ceramic and concrete planters. The bore was completely filled with wax including part of the threaded section. This didn't allow the threads of my grinder to engage all the way. But after removing all the wax the bit performs exactly as expected.

Pros

The diamond-coated drill bits are safer to use compared to other drill bits as they do not generate sparks

Cons

May cause chipping or cracking in delicate materials
