01V065 - Walter SF-3 Aluminum Cut Carbide Burr

Precision Engineering for Non-Ferrous Applications

The Walter 01V065 Carbide Burr SF-3 NF represents the pinnacle of rotary file technology, specifically engineered for the unique challenges of machining aluminum and other non-ferrous metals. In industrial environments, the efficiency of material removal is often compromised by the tendency of soft metals to adhere to the cutting edges of standard tools—a phenomenon known as loading or clogging. Walter has addressed this issue with a specialized Non-Ferrous (NF) cut geometry. This design features wide, deeply ground flutes that facilitate rapid chip evacuation, preventing the material from building up between the cutting teeth. The result is a burr that maintains its cutting aggression throughout the operation, reducing downtime associated with cleaning or changing tools.

Manufactured from the finest grade of tungsten carbide, this burr offers superior hardness and heat resistance compared to high-speed steel alternatives. The manufacturing process employed by Walter ensures impeccable concentricity between the head and the shank. This balance is critical in high-speed die grinding applications, as it minimizes run-out and vibration. Reduced vibration not only improves the surface finish of the workpiece but also significantly reduces wear on the grinder's bearings and lowers operator fatigue during extended use. The SF-3 shape, characterized as a tree shape with a radius end, is particularly versatile, allowing operators to grind contoured surfaces, blend fillets, and access confined areas with ease.

For professionals seeking reliability and precision, the Walter SF-3 NF burr delivers consistent performance. Whether used for enlarging holes, deburring castings, or fine finishing, the tool's ability to resist loading while maintaining a high removal rate makes it an indispensable asset in any fabrication shop dealing with aluminum, copper, or brass. The robust steel shank is induction brazed to the carbide head, ensuring a bond that withstands the thermal and mechanical stresses of heavy-duty industrial use.
