Geometric Characteristics of Tungsten Carbide Drill Bit Ⅴ

In last part we know that tungsten carbide drill bits can have various shank length, straight or tapered, and the diameter-to-length ratios range from 1:1 to 1:10 or up. This part we give a table listing tool geometries recommended for some commonly drilled materials.

The best geometry of tungsten carbide drill bits to use depends upon the properties of the material being drilled. The following table lists geometries recommended for some commonly drilled materials.

(The end. This article is divided into several parts. Here is part 5. For part 4, please refer to http://news.chinatungsten.com/en/tungsten-information/80549-ti-10419)
