Tungsten Carbide Forstner Bits Ⅵ

In last part we know that tungsten carbide drill bits have special cutting rims, which make them able to drill holes cleanly, more precisely, faster and better than other bits, and are multifunctional as well. In this part we explain the drawbacks and precautions to use a Forstner bit.

In most cases all tungsten carbide Forstner bits are intended for mounted drill presses rather than hand-held tools. They typically require a lot of force, which can be dangerous and sometimes even unwieldy on a smaller appliance.

So people who want to use it typically have to invest in a drill press, and even then they often have to have at least a bit of training in order to control and properly use it. The bits also tend to be somewhat difficult to sharpen, and they don’t have any way of blowing dust back out the way some bits do; what this means in practical terms is that carpenters may have to pause more often to clear the bores. These bits also tend to be a bit more expensive than their counterparts.
