Product Description
Carbide Drill Bit
Carbide drill bit is a kind of equipment used in drilling engineering. It is a drill bit used for core drilling. The steel cylindrical drill bit body is welded with tungsten carbide carbide cutting tools. The shape of the carbide cutting tools and the number of inlays, arrangement, and welding angles on the drill bit are called bottom blade, inner blad,e, and outer blade to ensure that there is a gap for water flow and powder removal. The upper part of the drill bit body is threaded to connect the core tube. There is a water trough on the side of the drill bit body and a water outlet on the bottom lip. The water trough and the water outlet are both to ensure the circulation of flushing fluid to remove rock powder and cool the drill bit. To increase the gap when drilling into clay and shale formations, ribs are welded on the inner and outer walls of the carbide drill bit, which is called a rib-type drill bit. Needle-shaped carbide self-grinding drill bits can be used in hard formations with high abrasiveness.
The classification of carbide drills includes: solid carbide drills, carbide indexable insert drills, welded carbide drills, replaceable carbide crown drills, etc.
The multi-layer geometric cutting end blade improves the drainage performance and can maintain a small cutting resistance. In addition to the commonly used right-angle shank, there are also a variety of shank types available, suitable for a variety of drilling rigs and drilling machines.
Working Principle Of Cemented Carbide Drill Bits
Cemented carbide drill bits rely on the impact load generated by drilling pressure and their rotation to break rocks. During rock drilling, the drill bit is subjected to high-frequency impact loads and multiple composite stresses such as torsion, bending, stretching, and compression. It is also subjected to wear and corrosion from working media such as rock, rock powder, and mineral water in a high-speed rotating collision environment. Most of the roller bits used at home and abroad are three-roller bits.
Drill Manufacturing Process: Cutting Process Of Grooves, Recesses, And Tips
Carbide blank bar cutting (generally using fast wire cutting to cut the bar to the required length), centerless grinding (grinding the bar to the required size, mainly processing the shank neck part in place) cylindrical grinding (processing the blade length part to the required size), or directly using the cylindrical grinding to grind the blank to the required size. After completing the above steps, you can use the tool grinder for processing, first grooving, then grinding the drill tip, and finally grinding the chisel edge. At this point, a carbide drill is formed, and some types of drills need to blunt the edge. After grinding the drill, selective coating is performed. This completes the manufacturing of the carbide drill, and it can be installed on the machine tool for drilling.
Carbide Drills Are Commonly Used For The Following Purposes
1. Metal drilling: Carbide drills are commonly used to drill holes in metals, including stainless steel, cast iron, and hardened steel. These materials will quickly dull traditional high-speed steel drills due to their toughness, so carbide drills are preferred for their ability to maintain a sharp edge and withstand the heat generated during the drilling process.
2. Composite materials: Carbide drills are also effective for drilling holes in composite materials, such as carbon fiber-reinforced plastics (CFRP) and fiberglass. These materials are very abrasive and will quickly wear out standard drills.
3. Hard and brittle materials: Carbide drills are suitable for drilling hard and brittle materials such as ceramics, porcelain, and some types of glass. These materials are more likely to break or chip, but carbide drills can reduce the risk of damage.
4. High-temperature applications: In applications where drilling generates a lot of heat, such as high-speed machining, carbide drills can hold their cutting edges better than high-speed steel drills.
5. Precision and Accuracy: Carbide drills are often used in applications where precision and accuracy are critical, such as the aerospace and medical industries. The durability and consistent performance of carbide drills help maintain tight tolerances.
6. Industrial and Manufacturing Processes: Carbide drills can be used in a variety of industrial and manufacturing processes, including automotive production, aerospace manufacturing, and machining.

Strong And Practical
Carbide drill bits contain fine particles of tungsten steel, and high-performance steel-tungsten drill bits are more strong and practical.
Good Chip Removal Effect
Scientific groove design makes it smooth chip removal and does not stick to the knife.
Sharp And Wear-Resistant
Sharp cutting edge, durable, sharp, and wear-resistant, not easy to break.
High Finish
The surface of the drill bit is smooth and sharp, and it is not easy to be contaminated with impurities and dirt.
Multiple Specifications Of Handle Types
In addition to the commonly used right-angle handle, there are a variety of handle types available, suitable for a variety of drilling rigs and drilling machines.
