Polishing disc Proxxon 28 308 — diameter 5 cm, thickness 1.3 cm

Polishing disc Proxxon 28 308 is a rigid accessory with a diameter of 5 cm and thickness of 1.3 cm, designed for detail polishing tasks with rotary and handheld tools. The disc is intended for surface finishing, deburring and smoothing of small parts made of metal, wood and plastic. A 12.7 mm bore ensures secure mounting on compatible Proxxon attachments and many standard rotary tool arbors.

Advantages

The disc’s compact 5 cm diameter and 1.3 cm thickness provide controlled contact area for precision work on small surfaces. Its rigid construction reduces wobble during rotation and helps deliver a consistent finish. Standard 12.7 mm bore simplifies attachment to a wide range of rotary tool collets and adapters, making it versatile for detail jobs. The product is suitable for repeatable surface preparation before painting, polishing seams and removing light burrs without aggressive material removal.

How to use

Install the disc onto the rotary tool arbor or adapter matching the 12.7 mm bore and ensure it is secured according to the tool manufacturer’s instructions. Run the tool at an appropriate speed for the material being worked on; lower speeds are recommended for delicate surfaces and fine finishing, higher speeds for light deburring. Apply light, even pressure and move the disc steadily across the workpiece to avoid heat buildup or uneven removal. Inspect the surface frequently and finish with finer abrasives or polishing compounds if a higher gloss is required.

Usage recommendations

Use personal protective equipment such as safety glasses and dust mask when polishing. Test on a scrap piece before working on the final part to determine optimal speed and pressure. Avoid excessive force and continuous contact in one spot to prevent overheating or damage to the workpiece.
