Flap Disc AWTools AW56025 125 mm P120 Zirconia for Metal and Stainless Steel

AWTools flap disc AW56025 125 mm P120 Zirconia is an abrasive wheel designed for grinding and finishing metal and stainless steel. Constructed from zirconia-coated cloth flaps, the disc fits standard 125 mm angle grinders and delivers steady material removal with controlled stock take. It is intended for surface preparation, edge blending and smoothing after welding, deburring sharp edges and efficient rust and paint removal on ferrous and stainless substrates.

Advantages

The zirconia abrasive formulation provides a balance of cutting speed and durability, maintaining consistent abrasive life across the disc surface. The flap construction conforms to contours and reduces the risk of gouging, yielding a more uniform finish compared with single-layer wheels. Its P120 grit offers medium-fine abrasion suitable for both initial metal shaping and final surface refinement prior to painting or welding.

Suitable for

• Grinding and blending weld seams on steel and stainless steel
• Deburring and edge rounding on fabricated parts
• Surface preparation before coating or painting
• Rust, scale and old paint removal from metal surfaces
• Contour finishing on irregular or curved components

Key specifications

• Disc diameter: 125 mm
• Abrasive type: zirconia cloth
• Grit size: P120 (medium-fine)
• Design: overlapping abrasive flaps for conforming action
• Intended tool: compatible with 125 mm angle grinders
• Primary materials: carbon steel and stainless steel

How to use

Mount the flap disc securely on a compatible 125 mm angle grinder following the grinder manufacturer’s instructions and safety requirements. Start grinding with light, consistent pressure and keep the disc moving across the workpiece to avoid concentrated heat or gouging. For weld blending, approach the weld bead at a shallow angle and work progressively from coarse removal to finishing strokes. Replace the disc when the abrasive flaps are worn down or cutting performance decreases.

Usage recommendations

Use appropriate personal protective equipment including eye protection, gloves and hearing protection. Observe the maximum safe RPM of both grinder and disc, and allow the workpiece to cool between passes if heavy stock removal causes heat buildup. For stainless steel, use steady, moderate pressure and finish with a finer grit if a smoother surface is required before polishing or passivation.
