The 4inch Nylon Purple Diamond Grinding Disc is a high-performance abrasive tool independently developed by HTM, crafted for industrial surface treatment scenarios with performance comparable to traditional wire wheels. This non-woven grinding disc features low dust emission and anti-clogging properties, able to efficiently remove stubborn dirt, old paint films, rust, and burrs from workpiece surfaces. Pollution-free and non-transferable, it avoids secondary pollution to processed workpieces, and is widely applicable to metal processing, welding pre and post-treatment and other fields. It has become a preferred alternative to wire wheels for many manufacturers pursuing stable and safe operation.

Compared with wire wheels, this grinding disc significantly reduces vibration during operation, bringing a more comfortable operating experience for operators and minimizing spark generation to eliminate potential safety hazards in flammable and explosive working environments. It runs at a stable speed of 12000RPM, ensuring consistent grinding effects without sudden failure.
The grinding disc adopts advanced compounding technology; after grinding, the workpiece surface forms a uniform and rough texture, making coatings, adhesives and other substances applied in subsequent processes adhere more firmly to the surface. It perfectly solves the problem that traditional abrasive materials cannot effectively improve post-process adhesion.
Made of high-quality raw materials, the grinding disc has excellent wear resistance and maintains stable performance during long-term continuous use, without the need for frequent replacement. Its anti-clogging design avoids efficiency reduction caused by blockage, effectively reducing the overall operation cost for users.
The 4inch Nylon Purple Diamond Grinding Disc is composed of three core components. First is the latest special adhesive material, which ensures strong bonding between internal components and extends the service life of the disc. Second is high-strength nylon fibers, the foundation for the grinding disc’s structural strength. Third is scientifically mixed multi-type abrasives, formulated according to professional grinding requirements to achieve efficient surface treatment effects. The product is equipped with a 19mm inner diameter plastic cap by default, and customized glass fiber caps are also available to meet different installation needs.

It can quickly and thoroughly remove rust layers and old paint films on metal surfaces without damaging the substrate, ideal for the maintenance of steel structures, auto parts and other metal products.
It is used for cleaning welding areas to remove oil stains and oxides before welding, and can also polish welding seams to make the surface smooth and uniform after welding.
It efficiently removes burrs and sharp edges on castings, machined parts and other workpieces, improving product finish and use safety.
It can clean various stubborn industrial dirt on workpiece surfaces that are difficult to remove by conventional methods, keeping the workpiece surface clean and tidy for subsequent processing.
Wear professional protective equipment during operation, including goggles, dust masks and gloves, to avoid injury from dust and debris.
Do not exceed the rated speed of 12000RPM during use to prevent the grinding disc from breaking due to excessive speed.
Check the appearance of the grinding disc before use; do not use the product if there are cracks, deformation and other defects.
Ensure that the grinding disc is firmly installed on the equipment; stop the machine immediately for inspection if there is abnormal vibration during operation.
It is suitable for various types of angle grinders and polishing machines that match the inner diameter size, and is widely used in industrial processing, equipment maintenance and metal surface treatment scenarios.
Yes. The default grit size is 180#, and we support professional customization in the range of 46# - 600# to meet different grinding, polishing and deburring requirements.
It is mainly designed for metal workpiece treatment. For non-metallic materials such as wood and plastic, it is recommended to consult our technical team in advance to select the appropriate grit size and processing parameters.
