It has been thought that drilling must be carried out at lower feed and cutting speeds, which was once correct in the processing conditions of ordinary drills. Now, with the advent of cemented carbide drills, the concept of drilling has also changed.
In fact, through the correct selection of the appropriate carbide drill bit, Ultra Coarse Carbide Drilling Insert can greatly improve the drilling productivity, reduce the cost per hole processing.
Selection of Carbide drill bit considerations:
1. Processing accuracy
2. Processing stability
3. Chip and coolant
4. Processing cost per Hole
Application and characteristics of cemented carbide bit
1. Can be suitable for more complex material drilling, Ultra Coarse Carbide Drilling Insert can choose a higher cutting speed.
2. Selected alloy bit special high-performance alloy blade, effectively reduce the knife collapse, maintain good wear resistance.
3. Multi-layer geometry cutting end blade, Ultra Coarse Carbide Drilling Insert improve excretion performance, maintain small cutting resistance.
4. In addition to the common right angle handle, with a variety of handle type, suitable for a variety of drilling rig, drilling machine.
Carbide drills are also of a different type, and the various models are suitable for different material drills. For example, loose plasticity of rock material is more suitable for the use of spiral rib drill bit, and homogeneous marble, limestone, shale materials will use square-shaped bit! Ultra Coarse Carbide Drilling Insert The selection of cemented carbide drills is also varied, which requires us to choose according to the actual situation. Choosing the right carbide drill can greatly improve the working efficiency and even reduce the cost. In fact, cemented carbide drills are divided into four basic types, monolithic cemented carbide bits, cemented carbide indexable inserts, Ultra Coarse Carbide Drilling Insert welded carbide drills and indexable carbide-tipped bits. These four types of cemented carbide bits have their own scope of use, cemented carbide indexable inserts are more commonly used in machine tools or lathe processing. However, the life cycle of course is not the same, relatively durable is the replacement of cemented carbide crown drill.
The function of cemented carbide bit
The whole cemented carbide bit is mainly made of fine grained cemented carbide, although a whole cemented carbide can only be milled about 10 times, however, in order to prolong its service life manufacturers have carried out coating treatment, the function of self centering also makes the whole cemented carbide bit more practical. Ultra Coarse Carbide Drilling Insert The machining aperture range of carbide indexable inserts is very wide and practical. Welded carbide bits work with high accuracy and most materials can be drilled. The replaceable cemented carbide crown bit not only has the function of self centering, but also has high precision with the welding type carbide bit.
