A Brief Introduction to Carbide Drill Bits
Higher Performance Carbide Drill Bits
Carbide drills are a type of high-performance drill, particularly suitable for use in advanced machining centers. These drills are made from fine-grained carbide materials and have undergone TiAlN coating treatment to extend their service life. Their specially designed geometric cutting edges provide self-centering functionality, ensuring good chip control and removal performance when drilling most workpiece materials.
The self-centering function and strictly controlled manufacturing precision of carbide drills can ensure the quality of hole drilling, and in some cases, no further finishing is needed after drilling.
Additionally, these drills perform exceptionally well on machining centers, CNC lathes, or other high-rigidity, high-speed machine tools.

01. Locating Drill Series
- Special cutting edge design, less likely to chip during locating machining, greatly extending product life
- Can simultaneously complete V-groove chamfering and grooving

02. High-Performance Machining Drills
- Effectively suppresses burr formation at the entrance and exit of the drilled hole
- No need for locating hole machining, improving processing efficiency

03. Flat Bottom Drills
- Suitable for various forms of machining
- Excellent chip flute design, providing better cutting performance
- The tip R corner can be processed according to customer requirements
Key Advantages of Carbide Drills
Extended Tool Life
TiAlN coating treatment provides superior wear resistance and heat resistance, significantly extending the service life of the drills.
Precision Machining
Self-centering design ensures precise hole placement and consistent quality without additional finishing operations.
Material Versatility
Designed to handle a wide range of materials from soft aluminum alloys to tough stainless steels and cast iron.
