Diamond drill bits – Charts and Reviews

Diamond drill bits last up 20 times as long as a bare tungsten carbide tool. In some cases it could last even longer than that. This will allow almost any job to be done completely with one tool with no change due to wear, no interruption and no recalibration, and this allows lights-out operation. Some materials, especially when heated, will absorb carbon from the coating. Working with ferrous materials results in premature wear and the tool cannot pay for itself.
