Key Features & Benefits

1. Advanced Aluminium Oxide Abrasive

• Multi-Material Mastery: Premium aluminium oxide grains provide an optimal balance of sharpness and durability, effectively working on metals, stainless steel, wood, plastic, and painted surfaces.

• Consistent Performance: Engineered for a cooler cut and longer lifespan, reducing frequent disc c

• hanges and downtime.

2. Innovative Plastic (Phenolic) Backing

• Superior Flexibility & Conformity: The plastic backing offers exceptional flexibility compared to traditional fiberglass, allowing the disc to perfectly conform to complex curves, contours, and irregular surfaces without cracking.

• Enhanced Safety & Reduced Vibration: Provides a smoother, more controlled operation with dampened vibration, decreasing operator fatigue and improving finish quality.

• Ideal for Delicate Surfaces: The added flexibility minimizes gouging risks on softer materials like wood or on

• finished surfaces.

3. True Multi-Surface Versatility

• Metal & Stainless Steel: Effectively grinds, blends, and finishes welds, removes rust, and prepares surfaces. For stainless steel, use a dedicated disc to prevent iron contamination.

  
  

• Wood: Smooths rough wood, shapes edges, and removes old finishes without excessive tearing typical of harder discs.

• Other Surfaces: Suitable for plastics, fiberglass, and body filler, making it a true all-rounder for workshops and fabrication shops.

4. Engineered for Pneumatic Power

• High RPM Stability: Specifically rated for the sustained high speeds of pneumatic angle grinders, ensuring integrity and safety during operation.

• Cooler Running: The combination of flap design and plastic backing, paired with the air-cooling effect of pneumatic tools, significantly reduces heat buildup.

Application Guide

For Metal & Stainless Steel:

• Use medium to fine grits (80-180) for finishing. Start with a coarser grit for heavy weld blending.

• Move the grinder in a consistent, controlled motion to achieve an even scratch pattern.

• Crucial for Stainless: To prevent "rust spots" from cross-contamination, use a brand-new disc reserved only for stainless steel.

For Wood:

• Use fine grits (120-180) for final sanding and shaping. Avoid very coarse grits to prevent grain tear-out.

• Let the flexible disc glide over the surface. Avoid excessive pressure to allow the abrasive flaps to do the work smoothly.

• Excellent for smoothing edges, curved furniture parts, and removing old paint or varnish.
