Polishing supply Proxxon 28840 rotary tool — metal polishing accessory, 2 cm diameter, silver

Proxxon 28840 rotary tool polishing supply is a metal polishing accessory with a 2 cm diameter and a silver finish, designed for precision surface finishing on small parts. The accessory is 0.6 mm thick and mounts on rotary tools with a 2.35 mm shaft diameter, making it compatible with many Proxxon tools and similar collet systems. It is intended for polishing and light cutting or sanding of metal, plastic and other materials where fine edge control and smooth surface results are required.

Advantages

This polishing supply combines a compact 2 cm working diameter with a thin 0.6 mm profile that enables access to narrow spaces and fine detail areas. The accessory’s silver finish and balanced construction support consistent contact with work surfaces, and the 2.35 mm shaft ensures straightforward mounting in standard rotary tool chucks. Because it is suitable for multiple materials, it reduces the need to change tools for small restoration, model-making and repair tasks.

How to use

Fit the accessory onto a rotary tool with a 2.35 mm collet or an appropriate adapter and secure it firmly according to the tool manufacturer’s instructions. Start at low speed to check balance and contact, then increase speed gradually to the recommended operating range for the material. Use light, even pressure and move the tool steadily across the surface to avoid overheating or gouging. For cutting or sanding ceramic and similar brittle materials, use a controlled, low-aggression approach and allow the tool to do the work rather than forcing it.

Usage recommendations

Wear appropriate personal protective equipment such as safety goggles and a dust mask when polishing or cutting. For best results, test on a scrap piece first to confirm speed and pressure settings. Replace the accessory if it shows significant wear, warping or imbalance to maintain safe operation and consistent finishing quality.
