14B112 - Walter Inox+ 3/4" x 18" File Belt, 120 Grit

Industrial-Grade Finishing for Stainless Steel and Alloys

The Walter 14B112 Inox+ Portable File Belt is a high-performance abrasive solution engineered specifically for the demanding requirements of industrial metal finishing. In maintenance, repair, and operations (MRO) environments where precision and longevity are paramount, this 3/4" x 18" belt stands out by delivering consistent results on stainless steel and aluminum components. The belt is constructed on a heavy-duty Y-polyester backing, a material chosen for its exceptional tensile strength and resistance to stretching under high tension. This robust foundation ensures that the belt maintains its structural integrity even when subjected to the aggressive pressure often required to remove welds or blend surfaces in tight quarters.

A critical technical advantage of the Inox+ series is the incorporation of advanced cooling additives within the abrasive matrix. Stainless steel is notoriously susceptible to heat discoloration and warping during abrasive processes. The specialized formulation of the 14B112 actively dissipates heat at the point of contact, allowing operators to work efficiently without compromising the metallurgical or aesthetic quality of the workpiece. This "cool cut" technology extends the life of the abrasive grains by preventing premature glazing, a common failure mode in standard belts when working on nickel alloys.

Furthermore, the manufacturing process of these belts utilizes a precision butt-joint technique reinforced with specialized adhesive. Unlike lap joints that can cause chatter marks or vibration, the butt-joint ensures a seamless transition as the belt rotates over the contact wheel. This results in a smoother finish and reduces mechanical stress on the file belt sander itself. With a 120 grit profile, this specific SKU is optimized for the intermediate to final finishing stages, effectively blending scratch patterns to prepare surfaces for polishing or to achieve a uniform satin appearance. It is an essential consumable for fabrication shops dealing with architectural stainless steel, food processing equipment, and pharmaceutical vessel maintenance.
