PCD Solid Nib End Mill
Engineered for ultimate rigidity and small-diameter machining excellence. Our custom PCD solid nib end mills feature a solid polycrystalline diamond head brazed to a carbide shank. This advanced design allows for complex multi-flute geometries, extremely small cutting diameters (from Ø1.0mm), and unmatched stability in highly abrasive materials.
Ideal Machining Operations
Precision Profiling & Corner Clearing Expertly designed for precision contouring, slotting, drilling, and cleaning up tight internal radii (rest machining) in high-tolerance components.
High-Speed Machining (HSM) & Mirror Finishing Optimized for light depth-of-cut finishing passes, delivering exceptional high-gloss and flawless mirror-like surface finishes.
Complex Cavity & Thin-Wall Milling Provides the ultimate structural stability required for chatter-free machining of complex pockets, deep cavities, and delicate thin-walled components.
- Extended Tool Life
- Reduced Cycle Time
- Consistent Precision
- Mirror Surface Finish
Core Advantages of Sundi PCD Solid Nib End Mill
Ultimate Structural Rigidity
The solid PCD head design eliminates the weak points of standard single-tip brazing, ensuring zero deflection and superior stability during high-speed small-diameter milling.
Complex Multi-Flute Geometries
Unlike standard brazed inserts, solid nibs allow for denser flute configurations (such as 3, 4, or 6 flutes) even on small diameters (1mm-6mm), significantly boosting your feed rates and efficiency.
Superior Small-Diameter Machining
Enables the manufacturing of small cutting diameters (down to Ø1.0mm) with extreme edge sharpness, ideal for intricate electronics, aerospace parts, and fine graphite details.
The Ideal PCD Tool Form
Representing the pinnacle of PCD tool design. A monolithic diamond cutting head allows for unrestricted, seamless helical geometries—just like solid carbide, but with the unmatched wear resistance of polycrystalline diamond.
