Dremel 520 Rotary Tool

The Dremel 520 impregnated polishing wheel is designed for light stock removal and producing a high luster finish on a variety of materials. Impregnated with silicon carbide abrasive and a cooling lubricant, the wheel eliminates the need for additional polishing compound and is suitable for detailed polishing tasks on metals and hard plastics.

Advantages

The impregnated wheel provides consistent cutting and polishing action without separate compounds, reduces heat buildup during use thanks to the cooling lubricant, and is compatible with many surfaces including steel, aluminium, brass, silver and gold. Its compact size and 3.2 mm shank make it suitable for precision rotary tools such as the Dremel 520.

Suitable for

• Light stock removal on metal and hard plastics
• High-luster polishing of jewellery metals (silver, gold, brass)
• Surface finishing on steel and aluminium components
• Precision polishing in model making and crafts

How to use

Secure the polishing wheel on the Dremel 520 or any compatible rotary tool with a 3.2 mm collet. Run the tool at appropriate speeds for the material being worked—start at a lower speed and increase as needed—while applying light, even pressure. Keep the wheel moving across the surface to avoid overheating or creating flats. No additional polishing compound is required because the wheel is pre-impregnated with abrasive and lubricant.

Recommendations

Use eye protection and appropriate gloves. Test on a scrap piece or inconspicuous area to confirm speed and pressure settings. Allow the wheel to cool between extended passes to maintain performance.
