Choosing the right core bit
First choose the hole diameter and your machine’s connection, for example 1 1/4" UNC or R 1/2". Then the material decides: reinforced concrete needs segments that cut rebar cleanly, while a fast-cutting bond suits masonry and brick.
The working length determines how deep you drill in one pass. Longer bits pay off for wall penetrations; short versions are enough for boxes and installations.
Wet or dry core drilling
Wet core bits work with water flushing, cool the segment and carry away the slurry, the right choice for concrete and large diameters on a rig. Dry core bits suit masonry and smaller diameters, ideally with dust extraction. Accessories such as pilot aids make a clean start easier.

Frequently asked questions
Usually they mean the same tool: a hollow bit with diamond segments that cuts a core out of the material. For small holes in tiles, use our tile drill bits.
Most core drilling machines use 1 1/4" UNC or R 1/2". You will find the connection in your machine’s manual and in each core bit’s technical data.
Often the segments have glazed or the water flow is too high. Reduce the water slightly and drill briefly into abrasive material to expose the diamonds again.
Yes. We inspect your core bit and replace the segments on request. Just contact us through our service.
