Description
FALCON Aluminum Oxide Fiber Discs are professional heavy-duty abrasive grinding tools built for ferrous metal fabrication, constructed with thick vulcanized fiber backing and premium brown fused aluminum oxide abrasive grains. Our lineup covers two mainstream mounting hole designs: standard round center hole and 4-tab cross star hole, perfectly matching all common rubber backing pads for electric and pneumatic angle grinders across global markets. Available in full grit range from aggressive coarse P36, medium P60/P80 to fine P120, these fiber discs satisfy full workflow demands from heavy stock removal, weld slag stripping, rust elimination to intermediate surface blending. The high-density vulcanized fiber base delivers exceptional tensile strength, resisting tearing, warping and cracking under heavy high-speed grinding pressure, drastically extending service life compared to cheap thin fiber discs. Each disc features wear-resistant printed green backing paper with clear FALCON eagle branding and grit marking, staying legible after long hours of continuous workshop use. The tough aluminum oxide abrasive grain owns excellent self-sharpening performance, maintaining consistent sharp cutting power without rapid dulling, while effectively reducing heat buildup to avoid workpiece burning, discoloration or thermal damage. Strict industrial safety production standards are applied to every batch, minimizing vibration and disc fracture risks during high RPM operation. Ideal for metalworking professionals, welders, auto repair technicians and construction contractors, these aluminum oxide fiber discs drastically cut down abrasive replacement frequency, lower overall workshop operating costs, and deliver stable, uniform scratch patterns for reliable daily metal grinding tasks.
