Abrasive zirconia flap disc EPM PRO-X 125 mm, grit 80 (E-552-1013)

Zirconia flap disc EPM PRO-X 125 mm, grit 80 is a coated abrasive wheel designed for efficient grinding and finishing of metal surfaces. The disc features overlapping zirconia-alumina flaps arranged on a backing plate to provide consistent material removal and uniform abrasion. It is intended for use with 125 mm angle grinders and delivers stable cutting performance on steel and other ferrous metals while offering longer life than conventional bonded grinding discs.

Advantages

The flap construction ensures continuous exposure of fresh abrasive grains, which maintains cutting efficiency and reduces glazing. Zirconia-alumina abrasive material combines high durability with good chip resistance for steady removal rates. The disc balances aggressive stock removal with surface smoothing, reducing the need for multiple passes. Its 125 mm diameter and medium coarse grit 80 make it versatile for blending welds, deburring edges, and preparing surfaces prior to painting or coating.

Suitable for

• Grinding and shaping welds on steel structures
• Deburring edges and removing sharp burs
• Rust and old paint removal from metal surfaces
• Surface blending and preparation before coating or painting
• General metal fabrication and maintenance work with angle grinders

Key specifications

• Disc diameter: 125 mm
• Abrasive type: zirconia-alumina (zirconia flap)
• Grit size: 80 (medium coarse)
• Construction: overlapping flaps on a rigid backing plate
• Intended tool: 125 mm angle grinder
• Application materials: steel and other ferrous metals

How to use

Mount the flap disc securely on a compatible 125 mm angle grinder following the tool manufacturer's mounting instructions. Operate the grinder at the recommended speed and apply steady, even pressure across the workpiece without forcing the disc. Move the disc in smooth passes along the surface to achieve uniform material removal and avoid dwelling in one spot to prevent overheating or gouging. Replace the disc when abrasive effectiveness declines or if the backing shows signs of damage.

Usage recommendations

For best results on steel, use the flap disc for initial stock removal with controlled strokes, then switch to finer abrasives if a smoother finish is required. Wear appropriate personal protective equipment including eye protection, gloves and hearing protection. Ensure proper ventilation when removing rust, paint or coatings. Store discs flat in a dry environment to preserve abrasive integrity.
