Flap Disc

Basic Info

A composite abrasive tool consisting of overlapping扇形 abrasive flaps (fiber-backed) or non-woven abrasive pads, secured by a central bolt to a metal backing plate (usually dish-shaped). Designed for angle grinders for large-area surface preparation like rust/paint removal, weld blending, and deburring.

Customer reviews

Elena Rodríguez · Toolroom Manager

We purchased your white aluminum oxide precision wheels for our HSS tool sharpening. The results are outstanding, achieving excellent edge finish and straightness that fully meets precision tool requirements. More importantly, your technical team provided highly professional selection advice, recommending the most suitable grit and hardness combination based on our equipment and material, avoiding common burning issues. Professional products coupled with professional service.

Marcus Weber · Production Manager

For the past six months, our workshop has fully switched to your company's CBN superabrasive wheels for camshaft finish grinding. The most immediate change was a reduction in single-part processing time by approximately 15%, and the wheel has not required dressing yet, with excellent dimensional consistency. Sparks in the grinding zone are noticeably reduced, indicating lower thermal impact on the workpiece. Overall calculation shows that despite the higher initial investment, the cost per part has actually decreased. A truly efficient and long-lasting tool.

Lucas Miller · Production Supervisor

Your grinding wheels deliver stable hardness—we use brown alumina models for carbon steel grinding, no workpiece burn or vibration issues. The wear resistance is better than our previous supplier, cutting our replacement frequency by 20%. Worth the investment.

Product Description

Product Features:

Unlike a wheel's point/line contact, its surface contact provides high material removal rates and uniform surface texture. Flexible flaps conform to slightly uneven surfaces. Large surface area aids heat dissipation, reducing workpiece thermal distortion. Two main types: with wire (aggressive cleaning) and without wire (fine finishing).

Product Specifications:

The flap/pad portion uses mainly aluminum oxide (metal) or silicon carbide (non-metal) abrasive. Grits range from very coarse P16 to fine P120. Backing plate diameters typically 100mm to 180mm, matched to grinder power. Center thread is commonly M14 (metric) or 5/8”-11 (imperial) for quick mounting.

Product Applications:

Weld seam blending and large-area surface preparation (e.g., SA2.5 cleaning) in steel fabrication, shipbuilding, tank construction. Paint stripping in auto repair. Deburring and cleaning of castings. Concrete surface profiling. A key tool for pre-welding or pre-painting treatment.
