OVERVIEW

Precision Engineering for Industrial Material Removal

The Walter 01V049 SM-3 Double Cut Carbide Burr represents the pinnacle of rotary file technology, designed specifically for heavy-duty industrial applications where precision and durability are paramount. Manufactured from premium-grade tungsten carbide, this tool is engineered to withstand the high thermal and mechanical stresses associated with grinding hard metals such as stainless steel and high-tensile alloys. The SM-3 shape, characterized by its pointed cone profile, is particularly effective for working in confined spaces, enlarging holes, and contouring irregular surfaces that standard grinding wheels cannot reach.

A critical feature of this Walter burr is its exceptional concentricity. Unlike inferior burrs that may wobble at high RPMs, causing chatter and premature wear on both the tool and the die grinder bearings, the 01V049 is balanced to perfection. This ensures a smooth operation that not only improves the surface finish of the workpiece but also significantly reduces operator fatigue during extended periods of use. The structural integrity of the carbide substrate ensures that the cutting edges maintain their sharpness far longer than high-speed steel alternatives, making this a cost-effective solution for high-volume production environments.

The "Double Cut" geometry features flutes cut in two intersecting directions, creating a cross-hatch pattern. This design is instrumental in breaking down chips into small, granular particles rather than long, sharp slivers. This efficient chip evacuation prevents loading of the flutes, allowing for continuous, aggressive material removal without the need for frequent cleaning. Whether used for weld preparation, flash removal, or fine finishing, the Walter 01V049 delivers consistent, high-quality results.

FAQ

Single cut burrs have one set of flutes and produce long chips, while double cut burrs (like this one) have cross-cut flutes that produce small chips and a smoother finish.

While it can cut aluminum, double cut burrs may clog (load up) with soft metals. An aluminum-cut (single cut with wide flutes) burr is recommended for aluminum.

This carbide burr is designed for use with pneumatic or electric die grinders and high-speed rotary tools.

SM-3 refers to a pointed cone shape, which is ideal for working in tight corners, angles, and for enlarging holes.

Yes, the tungsten carbide construction and double cut geometry make it excellent for use on stainless steel and other hard ferrous metals.

Always wear eye protection (safety glasses and face shield), hearing protection, and gloves. Carbide burrs spin at high speeds and throw hot metal chips.

Walter carbide burrs are manufactured with high concentricity to minimize vibration and chatter, provided the tool collet is in good condition.

This pattern, characteristic of the double cut design, allows for rapid material removal while maintaining a smooth finish and reducing the pulling action of the tool.
