Abrasive disc KLINGSPOR PS33BK 225 mm grit 180 for angle grinders

The KLINGSPOR PS33BK abrasive disc 225 mm grit 180 is a bonded, general-purpose grinding and sanding disc designed for use with angle grinders. It combines a P180 abrasive grain with a durable backing to provide controlled material removal and a consistent surface finish on a range of substrates. Intended for medium-fine sanding tasks, this disc is suitable for deburring, rust and paint removal, and preparing metal surfaces prior to welding or painting.

Advantages

The abrasive formulation and construction deliver an even abrasive action and predictable cut rate while maintaining surface quality. The 225 mm diameter offers broad coverage for faster processing of flat and mildly contoured areas. The P180 grit balances material removal with surface refinement, reducing the need for follow-up sanding steps. The disc is compatible with common angle grinder mounting systems and is built for stable operation under typical workshop conditions.

Suitable for

• Deburring and edge blending on sheet metal and fabricated parts
• Removing rust, scale and old paint from metal surfaces
• Surface preparation before welding, priming or painting
• Light stock removal and finish sanding on ferrous materials

Key specifications

• Diameter: 225 mm
• Abrade grit: P180 (medium-fine)
• Compatible tool: angle grinder
• Intended materials: metal and general-purpose surfaces
• Application: material removal, finishing, deburring, rust and paint preparation

How to use

Mount the disc securely on a suitable angle grinder following the grinder manufacturer’s instructions and ensure the machine is disconnected from power during fitting. Use appropriate rotational speed as recommended for abrasive discs and maintain a steady, controlled motion across the workpiece. Apply light to moderate pressure—let the abrasive do the work—to avoid overheating or excessive wear. Replace the disc if it becomes damaged, worn to an unsafe diameter, or if performance degrades.

Usage recommendations

Always wear appropriate personal protective equipment: eye protection, hearing protection, gloves and respiratory protection suitable for metal dust and paint particles. Inspect the disc for cracks or defects before use and follow the angle grinder’s safety guidelines. For best results on painted surfaces, begin with a test area to confirm finishing requirements and follow with progressively finer abrasives if a smoother surface is required.
