Sander Proxxon 28 492 Keyless 550 g

The Proxxon 28 492 Keyless Sander is a lightweight, compact electric sander designed for precise sanding and grinding tasks. It features a die-cast aluminium head with a multi-gear system running on several ball bearings housed in a glass-fibre reinforced polyamide main body. The tool includes a balanced, powerful and quiet DC motor with infinitely variable rpm control (full-wave electronics) and a keyless MICROMOT hardened steel collet system with sizes 1.0, 1.5, 2.0, 2.4, 3.0 and 3.2 mm. The sander is supplied in a stable polypropylene case for safe storage and transport.

Advantages

The aluminium head with ball-bearing-supported gears ensures stable running and long service life while the glass-fibre reinforced polyamide housing combines strength with reduced weight — the tool weighs approximately 0.55 kg. The special balanced DC motor delivers smooth, quiet operation and long durability. Infinitely variable speed control provides precise rpm adjustment for different materials and tasks. The set of hardened steel collets enables quick, keyless accessory changes and secure tool holding. The included high-grade polypropylene case offers robust protection and convenient storage.

Suitable for

• Precision sanding and grinding on wood, plastics and soft metals

How to use

Connect the sander to a suitable 220–240 V AC power supply. Select the required collet size and insert the accessory (e.g., sanding or grinding bit) into the keyless collet, securing it by hand according to the collet instructions. Adjust the rpm with the speed control to match the material and task, starting at a low speed and increasing as needed. Hold the tool with a firm but relaxed grip and guide it gently over the workpiece, avoiding excessive pressure. For right-angled separation of rods, secure the workpiece and use a suitable cutting or grinding bit while maintaining steady, controlled movements.

Recommendations

Use appropriate personal protective equipment (safety glasses, dust mask and hearing protection) and secure the workpiece before operation. Select the correct collet size for the accessory to ensure safe, concentric running. For best results, start at a lower speed and increase gradually; avoid overheating the accessory or workpiece. Store the tool and collets in the supplied polypropylene case when not in use.
