01V056 - Walter SB-1 Double Cut Tungsten Carbide Rotary File

Precision Engineering for Superior Material Removal

The Walter Carbide Burr SB-1 DC (01V056) represents the pinnacle of rotary file technology, designed for industrial professionals who demand precision, durability, and efficiency. Manufactured from the finest grade of tungsten carbide, this burr is engineered to withstand the high thermal and mechanical stresses associated with heavy-duty grinding and deburring operations. The SB-1 shape—cylindrical with an end cut—provides exceptional versatility, allowing operators to machine flat surfaces, contours, and right-angle corners with a single tool.

One of the defining characteristics of Walter's carbide burr line is the meticulous attention to concentricity and balance. A perfectly balanced burr eliminates the micro-vibrations that often lead to premature tool failure and operator fatigue (Hand-Arm Vibration Syndrome). This precise manufacturing ensures that the burr runs true in the collet, extending the life of both the consumable and the pneumatic or electric die grinder driving it. The result is a smoother operation that allows for greater control during delicate finishing tasks.

The "DC" designation stands for Double Cut, also known as an alternate diamond pattern. Unlike single-cut flutes that produce long, sharp chips, the double-cut geometry features cross-cut flutes that break material down into small, granular chips. This design significantly reduces tool loading and allows for rapid stock removal while simultaneously producing a finer surface finish. It is particularly effective on harder materials such as stainless steel and high-tensile alloys, where maintaining a cool cutting action is critical to preventing work-hardening of the base material.

Whether utilized for enlarging holes, leveling weld seams, or general surface finishing, the Walter SB-1 Double Cut Burr delivers consistent performance. Its robust construction ensures it retains its cutting edge longer than standard high-speed steel alternatives, making it a cost-effective solution for high-volume production environments.
