OVERVIEW

Smooth Control and Fast Metal Removal

For professional welders and fabricators, the Walter 01V049 SM-3 Double Cut Carbide Burr is the go-to tool for cleaning up welds, prepping joints, and fixing imperfections in hard-to-reach places. When you are working with stainless steel or hardened steel, you need a burr that bites into the metal without skipping or chattering. Walter has designed this burr with a double-cut pattern—often called a cross-cut—which creates smaller chips and allows for much smoother operator control. Instead of the tool trying to "climb" or pull away from the work, it stays where you put it, giving you the precision needed for detailed finishing work.

The pointed cone shape (SM-3) is incredibly versatile. It is perfect for getting into tight angles, deburring the inside of drilled holes, or shaping narrow contours where a flap disc simply won't fit. Because it is made from high-quality tungsten carbide, it holds its edge through the toughest jobs, meaning you spend less time changing out worn bits and more time fabricating. The balance of this burr is noticeable the moment you spin it up in your die grinder; the lack of vibration means your hands won't be numb after ten minutes of grinding, and you'll get a cleaner finish on the metal.

Whether you are enlarging a bolt hole that is just a hair off, removing weld spatter, or beveling an edge for a TIG pass, this burr delivers rapid stock removal with a fine finish. The double-cut teeth effectively pulverize the metal into manageable dust rather than dangerous long slivers, keeping your workspace cleaner and safer. Add the Walter 01V049 to your tool arsenal for a reliable, long-lasting solution to precision grinding tasks.

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.
