01W314 - Walter ALLSTEEL SF-3 Double Cut Carbide Burr Tree Shape

Technical Overview: Walter ALLSTEEL™ Carbide Burr SF-3

The Walter 01W314 is a premium-grade carbide burr from the ALLSTEEL™ series, specifically engineered for high-performance material removal on ferrous metals. This model features the SF-3 shape (Tree with Radius End), a geometry widely utilized for contouring, blending radii, and accessing confined areas where a rounded profile is required. Manufactured in the USA, these burrs are produced using advanced CNC machining and grinding processes that ensure concentricity and precise flute geometry. This attention to manufacturing detail results in a tool that maintains consistent cutting angles throughout its lifespan, reducing chatter and extending tool life.

The "Double Cut" configuration of this burr is critical for industrial applications. Unlike single cut burrs that produce long, sharp chips, the double cut design incorporates cross-flutes that break down material into small, manageable granular chips. This not only improves chip evacuation but also significantly reduces the pulling action often felt with single cut tools, allowing for greater operator control and reduced load on the spindle bearings of CNC machines or pneumatic die grinders. The carbide substrate is formulated to withstand the high heat and abrasion associated with grinding mild steel, stainless steel, and cast iron.

Industrial MRO professionals choose the Walter ALLSTEEL™ line for its reliability and consistency. The 01W314 is designed to operate effectively at high RPMs, typical of pneumatic die grinders, ensuring efficient stock removal without premature dulling. Whether used for weld preparation, leveling weld seams, or general deburring, this burr delivers a balance of aggression and finish quality that meets the rigorous demands of metal fabrication shops and maintenance departments.
