OVERVIEW

Precision Grinding with Extended Reach

The Walter Allsteel Carbide Burr (01W613) is a high-performance rotary file designed for industrial metalworking applications requiring both precision and accessibility. Featuring the standard SF-3 shape (Tree with Radius End), this tool is ideal for contouring, hole enlargement, and surface preparation in confined spaces. The defining feature of this model is its 6-inch extended shank, which provides the necessary reach to grind deep inside pipes, castings, and complex fabrications where standard length burrs fall short.

Engineered with Walter's proprietary Allsteel double cut geometry, this burr features alternating cutting teeth that rapidly shear material while breaking chips into small, manageable granular pieces. This design significantly reduces tool chatter and operator fatigue, ensuring a smoother finish and greater control during operation. The burr is manufactured from premium micro-grain tungsten carbide, ensuring exceptional hardness and resistance to heat buildup, even during prolonged use on tough materials like stainless steel and cast iron.

Manufacturing consistency is a hallmark of the Walter brand. Each burr is precision-ground to ensure perfect concentricity between the head and the shank. This balance is critical for extended-length tools, as it prevents dangerous wobbling and vibration at high speeds, protecting both the workpiece and the die grinder bearings. Whether used for heavy stock removal or fine deburring, the 01W613 delivers reliable, professional results.

FAQ

The SF-3 is a 'Tree Shape with Radius End'. It is versatile, used for rounding off edges, grinding contours, and working in tight, curved areas.

The Allsteel line is optimized for ferrous metals, including mild steel, stainless steel, and cast iron.

Double Cut burrs have cross-cut teeth that produce smaller chips, result in a smoother finish, and offer better operator control by reducing the tendency of the tool to 'climb' or pull.

This tool has a standard 1/4" shank diameter, compatible with most pneumatic and electric die grinders.

The 6-inch length allows you to reach deep into workpieces, such as inside pipes or engine manifolds, where a standard 2-inch burr cannot reach.

Yes. Extended shank burrs should be inserted into the workpiece before starting the tool or started at a lower speed to prevent 'whipping' or bending due to centrifugal force.

While it can cut aluminum, it is not recommended as the double-cut design may clog (load up) with soft aluminum. For aluminum, use a dedicated 'Alu-Cut' or single-cut burr.

The head diameter is 3/8 inch and the length of cut (head length) is 3/4 inch.
