Advantages of Tungsten Carbide Drill Fitting

One of the advantages of tungsten carbide drill fitting over the more common steel bit, is that they last longer, so long as nothing drastically wrong happens. Drills experience “Wear and tear” because the heat generated due to the friction between the bit and the surface being penetrated, causes the dulling of the bit. As a result, the drill bit needs regrinding from time to time, to maintain it’s cutting edge. However, there is a limited number of times that regrinding can be done before the drill becomes effectively useless. There is also the matter of the structural integrity of the bit, which gets compromised due to the repeated heating and cooling that the bit undergoes as it is put to work. As tungsten carbide drill fitting are tougher and more durable than their steel counterparts, they do not deteriorate as easily, and therefore have a longer lifespan, up to 25 times as much.

To appreciate another advantage of tungsten carbide drill fitting, we need to understand what is meant by drill tolerance. The tolerance of a drill basically is a measure that indicates the accuracy one can expect from the drill bit. It in effect is the difference between the diameter of the bit and the diameter of the largest expected hole generated from actually using the bit. The tolerance is associated with the size of the drill bit, as well as the type. As would be expected from the explanation of what tolerance refers to, the lower it is, the more accurate the bit. Tungsten carbide drill fittng have the lowest tolerances and are therefore the choice of drills for any task that requires high precision.
