Flap Disc AWTools AW56026 125 mm P150 Zirconia for Metal and Stainless Steel

Flap Disc AWTools AW56026 125 mm P150 Zirconia for Metal and Stainless Steel is a 125 mm (5") abrasive flap disc designed for metalworking tasks that require medium finishing and material removal. The disc uses zirconia abrasive grains for a balance of cutting speed and durability, suitable for preparing and refining steel and stainless steel surfaces, removing welds, deburring edges and smoothing joints. It fits standard angle grinders and is intended for applications where a consistent P150 grit finish is needed.

Advantages

The zirconia abrasive provides longer life and steady cutting performance compared with conventional aluminum oxide, reducing downtime for disc changes. The 125 mm diameter offers good access to confined work areas while maintaining stability during use on standard angle grinders. P150 grit ensures a medium‑fine finish suitable for follow‑up processes such as priming or painting. The flap construction conforms to contours for more even material removal and reduces the risk of gouging on thinner workpieces.

Suitable for

• Grinding and smoothing steel surfaces
• Finishing stainless steel components
• Deburring edges and removing sharp burrs
• Cleaning and preparing weld seams
• Surface preparation before coating or painting

Key specifications

• Disc diameter: 125 mm (5")
• Abrasive type: zirconia
• Grit size: P150
• Intended materials: steel and stainless steel
• Primary applications: grinding, deburring, finishing welds and edges

How to use

Mount the flap disc on a compatible angle grinder following the tool manufacturer's instructions and ensure the disc is secured correctly before operation. Use appropriate personal protective equipment such as safety goggles, gloves, and hearing protection. Start with light to moderate pressure, keeping the disc at a shallow angle to the work surface and move steadily to avoid overheating or creating uneven spots. For best results on welds and edges, maintain a consistent motion along the workpiece and inspect the finish periodically, switching to finer or coarser grits as necessary for the next processing step.

Usage recommendations

Use at recommended grinder speeds and avoid excessive side pressure to extend disc life. Store discs in a dry, cool place away from direct sunlight to maintain abrasive performance. For stainless steel, work with steady, controlled passes to minimize heat build‑up and reduce risk of surface discoloration.
