Key Benefits for Grinding, Deburring and Surface Finishing
Mianue Abrasives focuses on practical flap disc performance for metalworking users: controlled grinding contact, useful elasticity, stable abrasive exposure and flexible size selection. These features help importers and distributors build a clear flap disc product range for stainless steel fabrication, carbon steel processing, weld seam grinding and general surface preparation.
Alternative to resin grinding wheels
The flap disc can replace cymbal-type resin grinding wheels in suitable grinding and finishing work, especially when the operator needs elastic contact and smoother surface transition. For distributors, this gives customers an alternative abrasive disc for weld seam work, stamped parts, box-section edges and general fabrication tasks.
Stable grinding action
Overlapping abrasive flaps expose fresh abrasive during use, supporting self-sharpening behavior and consistent material removal. This helps the silicon carbide flap disc maintain useful cutting action across grinding, deburring and polishing stages when the correct grit is selected.
Tensile and bending resistance
The plastic base and coated abrasive construction are designed for strong elasticity, tensile strength and bending strength during matched operating conditions. A plastic backing flap disc is especially useful for buyers who need a stable backing plate with lighter handling and flexible grinding performance.
Suitable for weld seams and stamped parts
The product is positioned for grinding weld seams and stamped parts with edges inside box-like structures, while helping reduce working noise compared with more rigid grinding choices. It is suitable for workshops that need surface blending, edge smoothing and preparation before coating or polishing.

Choose by Grit, Size and Grinding Task
Choose the flap disc by matching grit, diameter and working task. Coarse grits support faster stock removal, medium grits are useful for deburring and blending, and finer grits help prepare a smoother surface before coating, painting or polishing. Size selection should follow the grinder, workpiece area and local market demand.
Flap Disc Grit Range: 40-320#
Use coarse grits such as 40# for heavier grinding, edge correction and faster stock removal on carbon steel or welded parts. Use medium grits such as 60# and 80# for common deburring, weld blending and surface leveling. Use finer grits from 120# to 320# when the application requires a smoother finish before painting, coating, decorative polishing or further surface treatment.
Common Sizes from 100mm to 230mm
100mm, 115mm and 125mm flap discs are widely used with handheld angle grinders and are practical sizes for hardware distributors, repair workshops and fabrication users. 150mm, 180mm and 230mm flap discs provide a larger working area for heavier structural components, industrial grinding coverage and applications where fewer passes are preferred.
Grinding, Deburring, Weld Blending and Polishing
This silicon carbide plastic base flap disc is positioned for grinding and polishing stainless steel and carbon steel structural components, especially weld seams, stamped parts, edge areas and box-section workpieces that require controlled contact. It is useful where a buyer needs a coated abrasive disc for grinding, blending and finishing rather than a single-purpose rigid grinding wheel.
