The 120mm Nylon Purple Diamond Flap Brush is a new-generation surface treatment tool launched by HTM, breaking through the limitations of traditional wire wheels and integrating high strength, durability and safe operation in one. This non-woven flap brush adopts a flexible structural design, which can better fit the complex surface of workpieces during grinding and realize efficient removal of rust, old paint films and stubborn dirt. With the advantages of low dust, no clogging and no transfer pollution, it is an indispensable precision processing tool for machinery manufacturing, automobile maintenance, hardware production and other industries pursuing high-quality surface treatment.

The flap brush adopts a multi-flap combination structure with strong flexibility, which can adapt to the grinding needs of curved surfaces, irregular edges and other complex workpieces, ensuring a uniform surface treatment effect without dead corners. It perfectly solves the problem that rigid abrasive tools cannot process special-shaped workpieces effectively.
Compared with wire wheels, the flap brush effectively reduces equipment vibration during operation, greatly reducing the fatigue of operators during long-term continuous work. It almost does not produce sparks during use, eliminating potential safety risks in workshops with flammable materials and fully meeting the safety production standards of various industries.
It supports extensive customization of core size parameters; the outer diameter, width and inner diameter can be adjusted according to the actual production needs of users, and can be perfectly matched with different types of industrial processing equipment, greatly improving the compatibility and applicability of the product in different production scenarios.
The 120mm Nylon Purple Diamond Flap Brush is made of high-quality composite materials with a compact internal structure. The core material is high-toughness nylon fibers, which provide stable flexible support for the flap brush and ensure perfect fit with workpiece surfaces. It is combined with a variety of abrasives with different particle sizes through the latest special adhesive, ensuring efficient and stable grinding performance. The connection between the flap and the base is firm and not easy to fall off during use; the default inner diameter is 19mm, and customized sizes are available to meet the installation requirements of different processing equipment.

It is specially suitable for the surface treatment of special-shaped workpieces such as curved metal parts, pipe fittings and hardware accessories, and can evenly grind the concave and convex parts of the workpiece to achieve a consistent surface effect.
It can quickly remove rust and paint on the surface of auto bodies, engine parts and mechanical components, and can also fine-polish the surface to restore the original luster of the workpiece without damaging the substrate.
It is used for professional post-welding treatment of welding seams, able to remove welding slag and oxide layers on the surface of welding seams, making the welding seam smooth and consistent with the overall surface of the workpiece.
It can accurately remove burrs and flashes on the surface of precision castings and stamping parts, without damaging the precision size of the workpiece, effectively improving the precision and quality of finished products.
Select the appropriate grit size according to actual processing requirements; coarse grit is suitable for heavy rust and paint removal, and fine grit is suitable for fine polishing and surface finishing.
During operation, maintain a proper distance between the flap brush and the workpiece; do not press too hard to avoid excessive wear of the flap and affect the service life.
Regularly clean the debris on the surface of the flap brush during use to prevent clogging and ensure stable grinding efficiency.
Store the flap brush in a dry and ventilated place when not in use; avoid contact with water and corrosive substances to prevent deformation and damage of the product.
The default outer diameter is 120mm, and we support professional customization from 7.5CM to 50CM (3inch to 20inch) to meet the surface treatment needs of different workpieces and processing scenarios.
The product is mainly designed for dry grinding; wet grinding may affect the adhesive performance of the internal materials and reduce the service life of the product, so it is not recommended.
Avoid overloading operation during use, clean the product in time after processing, and store it in a suitable dry environment. Selecting the appropriate grit size according to the actual processing requirements can also effectively extend the service life.
