Structure and design of carbide drills

Drill structure
Cutting edge: designed for cutting materials, shape and angle are adjusted according to processing requirements. Spiral groove: used to discharge chips, reduce chip accumulation and improve processing efficiency. Shank: used to connect with drill chuck or machine tool, common shank forms are straight shank and taper shank.
Design featuresHigh precision: The overall carbide drill has high dimensional accuracy and can ensure the accuracy of the processed hole. Optimized geometry: Improve cutting efficiency and surface quality by optimizing the design of cutting edge and spiral groove.

Application fields of carbide drills

1 Aerospace
Used for processing high-strength and high-hardness aviation materials, such as titanium alloys, aluminum alloys, etc. The demand for precision drilling is high, and solid carbide drills are an ideal choice.
2 Automobile Manufacturing
Processing engine cylinders, transmission housings and other parts.
High efficiency and high precision processing requirements have led to the widespread use of carbide drills.
3 Machining
Used for processing general mechanical parts, such as mold manufacturing, machine tool parts, etc.
Welded and indexable carbide drills are common types.
4 Construction and Infrastructure
In drilling holes in materials such as concrete and stone, carbide drills perform well.
In particular, coated drills can effectively resist material wear.

Use and maintenance of carbide drills

Choose the right drill: Choose the right drill type and size according to the processing material and process requirements. Cutting parameters: Reasonably set the cutting speed, feed rate and cutting depth to avoid excessive wear or damage to the drill. Cooling and lubrication: Use cutting fluid or cooling oil to reduce the impact of cutting heat on the drill.

Development trend of carbide drills

High-performance coating technology New coatings (such as nano coatings) can further improve the wear resistance and heat resistance of drills and extend their service life. Digitalization and intelligence combined with CNC technology can enable carbide drills to achieve higher precision processing. Intelligent tool systems can monitor the wear status of drills in real time and optimize the processing process.

Brand selection of carbide drills

There are too many tool brands to choose from, but you can choose according to one principle. First choose a brand, a big brand, domestic or foreign, because big brands are relatively stable. Performance matching According to the processing materials and process requirements, choose the appropriate drill type and coating. Cost performance Consider the service life and processing efficiency of the drill, and comprehensively evaluate the cost performance.
