Flap Disc AWTools 125 mm P40 INOX Zirconia A27181250401535

AWTools flap disc 125 mm P40 INOX Zirconia is an abrasive accessory for angle grinders, engineered for metalworking tasks such as grinding, deburring and surface blending on stainless steel and other ferrous materials. With a 125 mm diameter and coarse P40 grit, the disc offers high removal rates and stable performance across the working surface. The zirconia (INOX) abrasive is selected to withstand high temperatures and maintain cutting ability when working on hard or heat-sensitive metals.

Advantages

The construction combines overlapping abrasive flaps that wear evenly to preserve a consistent profile during use, resulting in uniform material removal and longer usable life compared with single-layer alternatives. Its P40 grit ensures aggressive stock removal while the zirconia abrasive reduces glazing and extends cutting action on stainless steels. The disc is balanced for straightforward mounting on standard 125 mm grinder flanges and designed to resist premature breakdown under continuous use.

Suitable for

• Removing weld beads and grinding weld seams on stainless steel
• Rapid stock removal and shaping of ferrous components
• Deburring sharp edges and blending surface transitions
• Preparing metal surfaces prior to painting or further finishing

Key specifications

• Disc diameter: 125 mm
• Abrasive type: zirconia alumina (suitable for INOX/stainless steel)
• Grit size: P40 (coarse)
• Application: angle grinder-mounted flap disc for metalworking

How to use

Select an angle grinder with compatible 125 mm flange and fit the flap disc according to the tool manufacturer’s instructions, ensuring secure mounting and correct rotational direction. Start grinding at moderate speed and apply steady, even pressure; allow the abrasive flaps to do the cutting rather than forcing the tool. Use progressive passes for controlled material removal and periodically inspect the disc for wear or damage. Replace the disc when abrasive performance drops or flap layers become excessively worn.

Usage recommendations

For best results on stainless steel, keep the grinder speed and applied pressure steady to reduce heat buildup and avoid altering the metal surface. Wear appropriate personal protective equipment, including eye, face and hand protection, and follow safety guidelines for angle grinder operation.
