Flap Disc KLINGSPOR 125 mm grit 40 model SMT 624 (MPN 222107)

Flap Disc KLINGSPOR 125 mm grit 40 model SMT 624 is a multi-layer abrasive disc designed for surface conditioning, weld blending, deburring and aggressive stock removal on metal and steel. With a 125 mm diameter and coarse 40 grit abrasive, the disc delivers consistent cutting action and a uniform finish thanks to overlapping abrasive flaps that wear evenly during use. It is intended for mounting on angle grinders with a 125 mm fitting and suits professional and workshop environments where reliable material removal and surface preparation are required.

Advantages

The flap construction ensures steady abrasive exposure and predictable performance throughout the service life, providing efficient removal rate with controlled finish. Its coarse grit allows rapid stock removal while preserving stability and balance during high-speed grinding. The disc is adaptable to a range of metalworking tasks, reduces heat concentration by distributing wear across flaps, and is easy to mount on standard 125 mm angle grinders.

Suitable for

• Removing weld spatter and blending weld seams on steel
• Deburring cut edges and chamfering metal parts
• Surface preparation before painting or coating
• Rapid material removal and shaping of ferrous metal components
• General metalworking and maintenance tasks in workshops

Key specifications

• Disc diameter: 125 mm
• Abrasive grit: 40 (coarse)
• Construction: multi-layer overlapping abrasive flaps
• Recommended tool: angle grinder with 125 mm mounting
• Application material: metal and steel

How to use

Securely mount the flap disc on a compatible 125 mm angle grinder following the grinder manufacturer's mounting instructions. Start the grinder at low speed to confirm balance, then operate at the recommended speed range for the disc and tool. Apply steady, even pressure and keep the disc moving across the work surface to avoid creating gouges or excessive heat. Replace the disc when abrasive performance drops or when flaps are excessively worn.

Usage recommendations

Use appropriate personal protective equipment including eye and ear protection, gloves and respiratory protection when grinding. Match disc speed to the grinder's rated RPM and avoid sideways or prying motions that can damage the disc. For best results on welds and heavy stock removal, use coarse grit 40 for initial passes, then follow with finer grit discs for smoother finishes.
