LUKAS Lamelka Sltflex 125MM ZKS P40 sanding disc 125 mm P40

LUKAS Lamelka Sltflex 125MM ZKS P40 is a 125 mm flap sanding disc with P40 grit designed for heavy material removal and surface preparation. The disc combines flexible flaps with a coarse abrasive grade to deliver aggressive cutting action on metal, wood and painted surfaces. Built for use on angle grinders and compatible sanding tools with the appropriate attachment, this flap disc is intended for tasks such as deburring, shaping and stripping old coatings prior to subsequent finishing.

Advantages

The flexible flap construction ensures even contact with irregular surfaces while maintaining consistent stock removal. The coarse P40 abrasive provides rapid cutting speed, reducing working time when removing weld spatter, paint or rust. The disc design dissipates heat more effectively than solid wheels, which helps prevent overheating of the workpiece during extended grinding. It is balanced for use at typical grinder speeds and offers predictable wear characteristics for planned consumable replacement.

Suitable for

• Deburring and edge blending on metal components
• Shaping and profiling of wood and composite materials
• Removing paint, rust and corrosion from metal surfaces
• Preparing surfaces for welding or repainting

Key specifications

• Disc diameter: 125 mm
• Abrasive grit: P40 (coarse)
• Disc type: flap sanding disc with flexible abrasive flaps
• Suitable tool: angle grinder or compatible sanding tool with matching attachment
• Main materials worked: metal, wood, painted/coated surfaces

How to use

Mount the flap disc securely on the grinder according to the tool manufacturer’s instructions and ensure the machine is switched off during fitting. Select a grinding speed within the safe operating range for the disc and the tool. Apply moderate pressure and move the disc across the workpiece in steady passes; allow the abrasive to do the cutting rather than forcing the tool. For best results on welds or thick coatings, work progressively from coarse removal to finer preparation before finishing.

Usage recommendations

Use appropriate personal protective equipment including eye and ear protection, gloves and respiratory protection when working with coarse abrasive discs. Keep the workpiece secured and check the disc regularly for wear or damage. Replace the disc when abrasive performance drops or flaps become excessively worn.
