Alumina Sanding Flap Disc

This Blue fused alumina alumina sanding flap Disc is specialized for polishing carton steel,mild steel and weld seam, and stock removal. Yandisc use strong fiber backing with many layers to ensure stable performance, less vibration and uniform grinding force during the contiguously using process.

This angle design make the abrasive flaps to keep maximum contact with the work-piece, offering efficient material removal, especially on curved surfaces.

T29 conical type design allows operators to grind or used between 15°to 25°. More efficient cutting on weld seams, welds fillets, and weld beads.

Compared with flat T27 discs, the conical T29 shape is more aggressive than flat T27 discs, providing more leverage and surface contact, more deeper and more stock removal. Best choice for for corners, edges, and uneven surfaces.

This alumina sanding flap Disc use special blue fused aluminum oxide abrasive grains. Which has similar character as zirconium flap disc but less production cost. Its advantage is sharp grinding, long durability and cost-effective. Best suitable for welding workshop, metal fabrication, machine repair and building operation team to achieve high grinding result with lower cost.

The fiber backing plate is lightweight and strong enough, which can make sure that operate can do smooth and comfort operation under heavy load. Available in multiple grits (#40–#120), this alumina sanding flap Disc can be used polishing from weld bead removal, heavy grinding to surface blending and pre-painting preparation.

Combining cost efficiency, cutting strength, and reliability, this T29 blue fused alumina flap disc is an excellent solution for industrial weld seam grinding applications.
