Description

Welded diamond tip for durability. Provides a quick, clean way to precisely drill through the densest, most abrasive tiles, including glazed ceramic and rock hard porcelain (both solid body and glazed). Reverse spiral threads permit continuous water cooling, so you can run the bits at higher speeds without fear of overheating. Core-ejection slot removes a plug of waste material, which is ideal for repetitive hole boring jobs.

* Maximum initial battery voltage (measured without a workload)
