Wet/Dry Diamond Core Drill Bit for Brick and Concrete with Pilot Bit, Adapter and Saw Blade

Cut clean, precise holes in brick and concrete with a diamond core drill bit built for wet or dry use.

Accurate masonry drilling with added convenience

When you need neat openings for installation work, this center drill bit helps you drill through red brick, concrete, foam brick, and similar materials with dependable control. The laser-welded diamond-grit head combines wear resistance with steady cutting performance.

The included pilot bit improves alignment, and center deviation is no more than 1 mm for more precise starts. Wet cutting can reduce dust, while dry cutting gives you flexibility when water use is not practical.

Its universal 5/8"-11 inner thread adapter fits handheld drills, making it easier to set up for masonry installation tasks such as air conditioning work, pipeline openings, stair railing installation, and general construction drilling.
