Flap Disc KLINGSPOR KM613 20×20×6 mm, abrasive grit 40, arbor-mounted (MPN 284743)

KLINGSPOR KM613 is a compact arbor-mounted flap disc designed for precision surface finishing of metal and stainless steel. With a 20×20×6 mm size and abrasive grit 40, this flap disc fits small grinders and rotary tools where controlled material removal and consistent abrasion are required. The stacked abrasive flaps conform to irregular surfaces and edges, enabling deburring, edge blending and light stock removal in confined or detailed work areas.

Advantages

The construction of the flap disc ensures even wear of the abrasive flaps and a steady cutting action, which helps maintain consistent surface quality. Its small diameter and arbor-mounted design provide high maneuverability and access to tight spaces. Grit 40 offers an aggressive balance between material removal rate and surface finish, making it suitable for preparing welds and removing scale or mill marks. The disc’s build reduces vibration compared with single-layer abrasives, improving control during precision tasks.

Suitable for

• Deburring and chamfering small metal parts
• Edge blending and weld dressing on steel and stainless steel
• Removing rust, scale or paint from confined areas
• Surface preparation before welding or coating
• Detail grinding on components with limited access

Key specifications

• Disc diameter: 20 mm
• Disc thickness: 20 mm
• Arbor thickness: 6 mm
• Abrasion grit: 40
• Intended materials: steel, stainless steel and other metals
• Design: stacked abrasive flap construction for controlled material removal

How to use

Mount the KLINGSPOR KM613 flap disc securely on a compatible small grinder or rotary tool with the specified arbor size. Start the tool at low speed to check attachment and balance before applying it to the workpiece. Use light, consistent pressure and move the disc across the work surface with steady, overlapping passes to achieve uniform abrasion. Allow the abrasive flaps to conform to contours rather than forcing the disc into tight corners; this preserves the abrasive life and helps prevent gouging. After use, inspect the disc for wear or damage and replace it if flaps are excessively worn or the mounting is compromised.

Usage recommendations

For best results when working on stainless steel, keep the disc moving to avoid localized heating and discoloration. Wear appropriate eye, hand and respiratory protection, and follow the tool manufacturer’s speed and safety guidelines for small grinders and rotary tools.
