Grinding Disc (125 mm) Glob LUKAS P80 Purple Grain — 125 mm abrasive flap disc, P80 grit

Glob LUKAS 125 mm grinding flap disc with P80 Purple Grain abrasive is designed for medium stock removal and surface preparation on metal and a range of general-purpose materials. Intended for use with standard angle grinders, the 125 mm diameter offers balance between accessibility in tight areas and enough surface coverage for efficient work. The P80 grit provides a medium cut rate and surface finish suitable for deburring, weld blending, rust and paint removal, and preparing metal prior to finishing.

Advantages

The flap disc construction combines multiple overlapping abrasive flaps on a stable backing to deliver even wear and longer life compared with single-layer discs. The P80 purple abrasive offers consistent cutting performance with controlled material removal and predictable surface texture. The 125 mm size is compatible with common angle grinders and allows precise control for both coarse and semi-finishing tasks, while reducing vibrations and chatter compared with aggressive grinding wheels.

Suitable for

• Deburring metal edges and removing sharp burs
• Blending and smoothing weld seams
• Removing rust, old paint and scale from metal surfaces
• Surface preparation before priming, painting or coating
• General-purpose metal fabrication and maintenance tasks

Key specifications

• Disc diameter: 125 mm
• Abrasive grit: P80 (medium)
• Abrasive type: Purple grain abrasive (medium-cut formulation)
• Design: Overlapping abrasive flaps on a backing (flap disc)
• Intended tool: Angle grinder
• Typical applications: Material removal, blending, cleaning and surface preparation on metal

How to use

Mount the 125 mm flap disc securely on an angle grinder according to the grinder manufacturer’s instructions and ensure the disc is rated for the grinder’s speed. Hold the grinder firmly and position the disc at a shallow angle to the workpiece to control stock removal and avoid gouging. Apply consistent, moderate pressure and move the disc across the surface with steady motions. For weld blending, start with light passes and increase pressure only if additional material removal is needed. Replace the disc when abrasive performance decreases or if any damage to the flaps or backing is visible.

Usage recommendations

Use appropriate personal protective equipment including eye protection, gloves and hearing protection. Ensure the workspace is well ventilated or use dust extraction when grinding. For best results on delicate or thin materials, test on a scrap piece first and use lighter pressure or finer grit if excessive removal occurs.
