PC03-N-7D and PC03-O-7D end mills are two high-performance milling tools that embody cutting-edge technology and exquisite craftsmanship, designed specifically to meet the modern manufacturing industry’s demand for high precision and efficiency. These end mills pursue ultimate precision and stability in structural design. The tool diameter (dc) is precision ground to ensure the accuracy of machining dimensions; the optimized design of the helical edge shape makes the cutting process smoother, effectively reducing cutting resistance and vibration, and improving the quality of the machined surface. At the same time, the reasonable design of the cutting edge length (lc) and overall length (L) ensures the strength and rigidity of the tool, while allowing it to easily handle difficult machining scenarios such as deep cavities and complex contours. A variety of products including solid carbide standard drills, 3D/5D/7D standard twist drills, 3D/5D/7D internal coolant twist drills, fixed-point drills, and more. We have designed a range of general-purpose machining series and specialized series of drills for aluminum alloy machining, offering a variety of models and specifications for your selection.
