Abrasive flap disc EPM PRO-X zirconia grit 40 Ø125 mm, brand EPM (E-552-1011)

EPM PRO-X abrasive flap disc with zirconia grit 40, Ø125 mm, is designed for use with 125 mm angle grinders. The disc features a layered flap construction and high-performance zirconia abrasive, providing aggressive material removal and stable cutting action on steel and metal alloys. It is intended for tasks such as weld cleaning, rapid stock removal, shaping and surface preparation where controlled abrasion and durability are required.

Advantages

The zirconia abrasive delivers a high removal rate and good resistance to glazing, while the overlapping flaps ensure consistent contact with the work surface for even wear and longer service life compared to conventional coated discs. The disc offers controlled grit exposure for predictable stock removal, reduced vibration during use, and compatibility with standard 125 mm angle grinders. Its construction helps maintain cutting performance under heavier loads and repeated use.

Suitable for

• Weld cleaning and weld seam finishing on steel
• Deburring edges and removing flash from metal parts
• Shaping and stock removal on steel and metal alloys
• Surface preparation before painting or coating
• Edge blending and smoothing of fabricated components

Key specifications

• Disc diameter: 125 mm (Ø125)
• Abrasive type: zirconia alumina (zirconia grit)
• Grit size: 40 (coarse, for aggressive material removal)
• Construction: layered flap design for even wear
• Intended tool mount: 125 mm angle grinder
• Primary materials: steel and metal alloys

How to use

Fit the flap disc to a 125 mm angle grinder following the tool manufacturer's instructions and ensure the grinder is disconnected from power during installation. Wear appropriate personal protective equipment including eye protection, gloves and hearing protection. Start the grinder at low speed to check for runout or imbalance, then use steady pressure and controlled passes to remove material. Maintain the disc at a moderate angle to the workpiece to optimise flap contact and cooling; avoid excessive side pressure that could overload the disc. Periodically inspect the disc for uneven wear or damage and replace when performance declines or flaps become excessively worn.

Usage recommendations

The flap disc is suited for aggressive stock removal on steel and metal alloys; for finer finishing or polishing use a finer grit flap disc. Keep the workpiece and disc cool by using intermittent contact and avoid prolonged dwell in one spot to extend disc life.
