01W344 - Walter SG-1 Double Cut Carbide Burr 6-Inch Extended Shank

Technical Overview: Walter Allsteel™ Carbide Burr SG-1 DC

The Walter 01W344 is a high-performance tungsten carbide burr designed for heavy-duty industrial applications. Part of the Allsteel™ series, this tool is engineered specifically for the rapid removal of material on steel and stainless steel workpieces. The burr features an SG-1 (Pointed Tree) geometry, making it particularly effective for contouring, milling in acute angles, and preparing surfaces in confined spaces. The defining characteristic of this specific SKU is its extended 6-inch shaft, which provides the necessary reach for internal pipe work, deep casting finishing, and maintenance in obstructed areas.

Technically, the burr utilizes a Double Cut (DC) flute pattern. This cross-cut design serves two critical functions: it reduces the size of the chips produced (granular chips rather than long, sharp slivers) and it balances the cutting forces to reduce tool chatter. The result is a smoother finish and significantly improved operator control compared to single-cut alternatives. Manufactured in the USA using precision CNC grinding, Walter burrs maintain strict concentricity tolerances. This ensures that the tool runs true in high-speed die grinders, minimizing vibration that can damage spindle bearings or cause operator fatigue during prolonged use.

The carbide substrate is selected for its hardness and heat resistance, allowing the burr to maintain its cutting edge even under the high thermal loads generated when grinding tough ferrous alloys. The shank is securely brazed to the carbide head, ensuring structural integrity at the high RPMs required for optimal carbide performance.
