Flap Disc 125 mm P120 Flat, Expert+ (pack of 10)

Flap Disc 125 mm P120 Flat, Expert+ (pack of 10) is a 125 mm diameter flap disc with P120 abrasive grit and a flat profile, designed for use on angle grinders. Supplied as a pack of ten discs, it is intended for material removal, surface preparation and finishing on metal and other substrates. The construction combines overlapping abrasive flaps to provide consistent cutting action and a balance between stock removal and surface quality during workshop, fabrication and maintenance operations.

Advantages

The flat profile and P120 grit deliver moderate material removal while maintaining control over surface finish, making the discs suitable for deburring, rust removal and smoothing welds. The flap design provides even wear and predictable performance over the life of the disc. Supplied in a pack of ten, the product ensures consistent replacement discs for ongoing projects and maintenance tasks.

Suitable for

• Deburring edges on steel and non-ferrous metals
• Removing rust and scale from metal surfaces
• Smoothing and blending weld seams
• Surface preparation before painting or coating
• General grinding and finishing with an angle grinder

Key specifications

• Diameter: 125 mm
• Abrasive grit: P120
• Profile: flat
• Pack quantity: 10 discs
• Intended tool: angle grinder

How to use

Mount the flap disc onto a compatible 125 mm angle grinder according to the grinder manufacturer’s instructions and ensure the disc is suitable for the grinder’s maximum RPM. Securely tighten the mounting flange and wear appropriate personal protective equipment, including eye protection, hearing protection and gloves. Use steady, controlled passes over the workpiece at a shallow angle for finishing or a slightly steeper angle where increased material removal is required. Allow the abrasive flaps to perform the work without applying excessive force; maintain consistent movement to avoid gouging.

Usage recommendations

Inspect discs before use for visible damage and replace any disc that is cracked or warped. For optimal results on steel, use moderate pressure and consistent motion; for non-ferrous metals, reduce pressure to avoid clogging. Store the pack in a dry environment away from direct sunlight to preserve abrasive bond and backing integrity.
