Many different materials are used for or on drill bits, depending on the required application. Tungsten carbide  and other carbides are extremely hard materials that can drill in virtually all materials while holding an edge longer than other bits. Due to their brittleness and high cost they are mainly used for drill bit tips, small pieces of hard material fixed or brazed onto the tip of a bit made of less hard metal.        Coatings Titanium nitride (TiN)  is a very hard ceramic material, and when used to coat a high-speed steel bit (usually twist bits), can extend the cutting life by three or more times. A titanium nitride bit cannot be properly sharpened, as the new edge will not have the coating, and will not have any of the benefits the coating provided. Titanium aluminum nitride (TiAlN)  is another coating frequently used. It is considered superior to TiN and can extend tool life five or more times. Titanium carbon nitride (TiCN)  is another coating and is also superior to TiN. Our company has drill probably in all material and all sizes which can benefit customer with the right kind of guidance and accurate 

Selecting a milling cutter is not a simple task. The below factors play important role as follows: Material: Carbide tools are more expensive than steel, but last longer, and can be run much faster, so prove more economical in the long run. HSS tools are perfectly adequate for many applications. The progression from HSS to cobalt steel to carbide could be viewed as very good, even better, and the best. Diameter: Larger tools can remove material faster than small ones, therefore the largest possible cutter that will fit in the job is usually chosen. When milling an internal contour, or concave external contours, the diameter is limited by the size of internal curves. The radius of the cutter must be less than or equal to the radius of the smallest arc. Our company helps to select the milling cutter and guides the customer for any technical support. We are best at serving the customers need and showing them the right products.
