Features and choice of solid carbide drills

Solid carbide drill bits is a complete carbide rods, use grinder processing. High strength, high hardness properties, fast cutting speed, wear resistance, red hardness and good, suitable for processing a variety of materials components. By cooling structure can be divided into non-cooling holes and there are two types of cooling holes. 1. Characteristics and uses (1) rigid, high strength, easy access to high precision core drill bit. (2) the material can be suitable for more complex drilling, selects a higher cutting speed. (3) effective to reduce chipping, has good wear resistance. (4) multi-layer geometry cutting tip edge, improving chip performance, maintain a smaller cutting resistance. (5) In addition to commonly used rectangular handle, the wide range of handles, suitable for a variety of drills, drilling machines equipped with. (6) compared with indexable insert drills, solid carbide hammer drill bits grinding times can be 7-10 times.
