Advantages and disadvantages of carbide bit

Advantages:
(1) Good rigidity, high strength, easy to obtain higher drilling accuracy.
(2) Can be suitable for more complex material drilling, can choose higher cutting speed.
(3) Effectively reduce blade breakage, with good wear resistance.
(4) Multi-layer geometric cutting edge, improve chip removal performance, keep small cutting resistance.
(5) In addition to the usual right-angle handle, equipped with a variety of handle, suitable for a variety of drill, drilling machine.
(6) Compared with indexable blade bit, the whole carbide bit can be repaired for 7 ~ 10 times.
Disadvantages: to grind well, grinding is not easy to collapse, the two main cutting edge height, Angle is the same, it is best to use grinding drill machine.
Extended information
Carbide bits are divided into four types of foundation: solid carbide bits, carbide indexable blade bits,
Welded carbide bits and convertible carbide crown bits. Each bit has the benefit of being suited to a particular machining premise.
(1) Solid carbide drill bit
(2) Carbide indexable blade drill
The drill with indexable carbide inserts can process a wide range of aperture sizes, and the processing depth ranges from 2D to 5D (D is the aperture), which can be used in lathes and other torsional machining machines.
(3) Welded carbide drill bit
The welded carbide bit is made by smoothly welding a carbide crown to a steel drill body. This kind of drill uses self-centering geometric edge type, cutting force is small, for most of the workpiece materials can achieve excellent chip control, machining the hole profile smooth degree is good.
Dimensional accuracy and positioning accuracy are very high, no need for subsequent finishing. The bit adopts internal cooling system and can be used in machining centers, CNC lathes or other high rigidity, high speed machine tools.
(4) Carbide crown bit can be changed
Convertible carbide crown bit is a new generation of drilling tools. It is composed of a steel drill body and a removable solid carbide crown. Compared with t
