EZARC Flap Disc 115mm 40 Grit zirconia grinding wheel 🛠

This 115mm flap disc from EZARC brings faster material removal for metalwork and heavy-duty surface preparation, combining coarse 40 grit with durable zirconia abrasive for robust stock removal. It is suited to smoothing welds, removing rust and blending surfaces when used on an angle grinder at typical working angles between 5 and 15 degrees.

Key Points

The flap design and Type 29 bevel profile make it easier to access edges and welded seams while keeping contact with curved or flat surfaces. The zirconia abrasive is tougher than standard aluminium oxide, which means the disc can stay sharper longer and handle more aggressive tasks. Fibreglass backing helps to absorb vibration and stabilise the grinding action, contributing to a steadier finish during prolonged use. For heavier metal work on stainless steel, cast iron and sheet metal, this 40 grit option prioritises speed of removal over fine finishing. ⚙️

Technical Specifications

• Name: EZARC Flap Disc 115mm 40 Grit Zirconia Grinding Wheel
• Diameter: 115 mm
• Grit: 40
• Arbor size: 22 mm
• Maximum speed: 13,300 RPM

Usage Recommendations

Use the flap disc on an angle grinder rated for the disc's maximum RPM and keep a steady, controlled motion to avoid digging in. For weld dressing and rapid material take-off start with light passes and increase pressure only if the tool remains stable. When working on stainless steel take care to avoid prolonged contact in one spot to reduce heat build-up, which can discolour the metal and affect temper. For a smoother result after initial grinding, follow with a finer grit flap disc or a polishing stage.

Nuances and Limitations

Although the zirconia construction gives longer life compared with aluminium oxide according to the manufacturer, a 40 grit disc is coarse and will not provide fine finishing. Consider switching to a finer grit for final smoothing and polishing. The disc is optimised for metal and can be used on wood for heavy stock removal, however the aggressive cut may be rough on delicate timber.
