Left hand carbide drill bits, micro drills,solid tungsten carbide drill bits,small carbide drill bits
Left hand carbide drill bits, are special drill bits for left hand machines. The situation in which the left drill has to be used are as follows:
When designing the gearbox of modular machine tool multi empty drill, it is not possible to add the intermediate wheel to change the direction limited by space.

What is Carbide ?
Carbide is one of the hardest material to be found and has amazing wear resistance capabilities that make it ideal material for cutting tools.Not only is it very hard ,but it is able to withstand a great deal of abrasion,which enables the carbide cutting tools to outperform other material.All our end mills are made of solid carbide.
