OVERVIEW

Precision Grinding for Non-Ferrous Metals

The Walter 01V003 Carbide Burr SA-3 NF is a high-performance rotary file engineered specifically for the unique challenges of working with soft, non-ferrous metals. Standard double-cut burrs often fail when applied to aluminum, copper, or brass because the soft material quickly packs into the flutes, rendering the tool useless and creating excessive heat. Walter's specialized Non-Ferrous (NF) cut geometry solves this problem with an open, aggressive flute design that effectively evacuates chips, preventing clogging and ensuring continuous, rapid stock removal.

Manufactured from the finest grade of tungsten carbide, this burr offers exceptional hardness and wear resistance. The SA-3 cylindrical shape is a staple in metal fabrication, providing a flat cutting surface ideal for deburring edges, smoothing contours, and finishing flat surfaces. With a head diameter of 3/8" and a length of cut of 3/4", it offers a versatile size for a wide range of fabrication tasks. The tool is precision-ground to ensure perfect concentricity, which translates to smoother operation, reduced vibration, and less operator fatigue during extended use.

Safety and tool longevity are paramount in the design of Walter carbide burrs. The 1/4" shank is hardened to withstand the torque and lateral forces of heavy-duty grinding. Whether you are enlarging holes, removing welds, or fine-finishing aluminum castings, the 01V003 delivers a superior surface finish without the frustration of material buildup. It is an essential tool for aerospace, automotive, and general fabrication workshops dealing with aluminum alloys.

Key Technical Benefits

Anti-Clog Design: Wide gullets and high relief angles prevent soft metals from welding to the cutting edge.
Vibration Control: Meticulous balancing reduces chatter, protecting both the workpiece and the die grinder bearings.
High Removal Rate: The coarse pitch allows for aggressive material removal without sacrificing control.

FAQ

The NF (Non-Ferrous) cut is specifically designed for soft materials like aluminum, copper, brass, zinc, and hard plastics. Its wide flute design prevents the material from clogging the burr.

The SA-3 is a cylindrical shape with a flat end (no end cut). It is ideal for surface grinding and contouring but not for plunging.

While tungsten carbide is hard enough to cut steel, the NF geometry is too aggressive (coarse pitch) for hard metals and may chip or cause excessive vibration. It is best to use a Double Cut burr for steel.

This burr has a standard 1/4" (6.35mm) shank, making it compatible with most industrial die grinders.

For a 3/8" diameter carbide burr, the recommended speed is typically between 20,000 and 30,000 RPM. Always refer to the manufacturer's specific safety charts.

No, the SA-3 specification typically refers to a cylinder shape without cutting teeth on the end face. It cuts only on the sides.

Good concentricity means the head is perfectly aligned with the shank. This reduces vibration (chatter), prevents premature wear on the grinder bearings, and produces a smoother finish on the workpiece.

The 01V003 is designed with an open structure to prevent loading. However, using a lubricant like wax or cutting oil can further assist in chip evacuation and extend tool life.
