EPM PRO-X zirconia flap disc 125 mm, grit 120, model E-552-1014

EPM PRO-X zirconia flap disc 125 mm, grit 120, model E-552-1014 is a 125 mm abrasive flap disc designed for surface grinding, blending and light stock removal on ferrous and non-ferrous metals. The zirconia alumina abrasive grain delivers consistent cutting performance and extended service life compared with standard abrasives. The disc is intended for use with angle grinders and provides a balance between material removal and surface finish for tasks such as weld cleaning, deburring and blending of metal surfaces.

Advantages

The zirconia construction ensures high resistance to glazing and faster cut rates on steel while maintaining grit integrity over prolonged use. A 125 mm diameter and fine 120 grit provide controlled stock removal with good surface refinement. The flap design promotes cooler cutting and more even wear across the disc, extending usable life and reducing the need for frequent disc changes.

Suitable for

• Weld cleaning and seam blending on steel and stainless steel
• Deburring and edge rounding after cutting or machining
• Surface preparation before painting or coating
• Light stock removal and finishing on metal parts

Key specifications

• Diameter: 125 mm
• Abrasive type: zirconia alumina
• Grit size: 120 (fine)
• Suitable tool: angle grinder
• Design: flap disc construction for progressive wear and consistent finish

How to use

Mount the flap disc securely on an angle grinder compatible with 125 mm discs and follow the grinder manufacturer’s safety and operating instructions. Use steady, even pressure and move the disc across the workpiece to avoid gouging; allow the abrasive to do the cutting rather than forcing the tool. Maintain the recommended operating speed of your grinder and replace the disc when wear reduces performance or safety markings indicate replacement is needed.

Usage recommendations

For best results on steel and stainless steel, use at moderate pressure and keep the disc moving to maintain an even finish. Wear appropriate personal protective equipment including eye protection, gloves and hearing protection. Store discs in a dry environment away from extreme temperatures and moisture to preserve abrasive performance.
