When working on demanding drilling projects, choosing the right type of core bit is essential to ensure efficiency, cost-effectiveness, and precision. Two of the most widely used types of diamond core bits in construction and industrial settings are sintered and vacuum brazed core bits. Each serves a specific purpose and performs differently depending on the material being drilled and the project's requirements.

Discover the incredible versatility of diamond cutting discs! Learn what materials they can cut (glass, tile, stone, concrete & more), how they work, and key safety & selection tips.

A quality sintered, laser-welded wet diamond core bit delivers 30–150 meters (100–500 ft) of total drilling in plain structural concrete and 10–40 meters (30–130 ft) in heavy rebar. Convert that to "holes" and you'll see anything from 20 to 250+ depending on your diameter and depth.
