M14 screw wool polishing wheel is a polishing consumable made from high-density pure wool felt. Compared with standard industrial felt, it is produced with an extended felting process, resulting in a denser fibre structure and finer pores. This construction delivers excellent wear resistance and superior polishing performance.

The key design feature is the M14 internal threaded mounting hole, which enables direct, secure attachment to power tools equipped with M14 spindles—such as angle grinders and polishing machines—allowing for quick installation and replacement. Depending on the application, the wheel is available in two main configurations: straight edge (flat-face) and rounded edge (domed/capped) types.

1. Core material: 100% pure wool felt, ensuring high dust-holding capacity and effective heat dissipation during polishing, helping to reduce the risk of workpiece burning.

2. Mounting specification: Universal M14 thread, compatible with most angle grinders and polishing machines.

3. Available sizes: Common diameters include Φ100 mm, Φ115 mm, Φ125 mm, etc.; thickness (height) typically ranges from 20 mm, 25 mm to 30 mm.

4. Operating speed: The recommended speed is generally 2,500–4,000 RPM. Always operate within the tool’s rated speed limits for safety.

5. Heat resistance: High-quality wool wheels can withstand temperatures up to approximately 300°C, suitable for prolonged continuous operation.

Widely used in glass products (scratch removal and edge polishing), automotive detailing (paint finishing), metalworking (mirror polishing of stainless steel and aluminum), woodworking & furniture (lacquer finishing), jewelry & accessories, and precision instrument surface treatment.
