Abrasive Flap Disc KLINGSPOR 125 mm, Grade 24 (MPN 45781)

The KLINGSPOR abrasive flap disc 125 mm, coarse grade 24, is designed for heavy material removal on metal surfaces and weld seams when used with angle grinders. Constructed from overlapping abrasive flaps, the disc provides consistent cutting action and controlled stock removal, making it suitable for preparation and finishing tasks in metal fabrication, welding shops and maintenance environments. The 125 mm diameter balances contact area and maneuverability for common grinder sizes.

Advantages

This flap disc offers aggressive stock removal combined with a predictable wear pattern thanks to its layered flap design. The coarse 24 grit achieves fast grinding of weld beads, sharp edges and excess material while maintaining an even surface profile. The disc construction supports reduced vibration and stable performance during prolonged use, enabling efficient metal grinding and blending operations.

Suitable for

• Grinding and blending weld seams on steel and stainless steel
• Removing scale, rust and paint from metal surfaces
• Deburring cut edges and smoothing rough metal contours
• Preparing surfaces for welding and coating

Key specifications

• Diameter: 125 mm
• Grit size: coarse 24 for fast material removal
• Compatible tool: angle grinder with matching disc arbor
• Disc design: overlapping abrasive flaps for uniform wear
• Target material: ferrous metals, stainless steel and similar alloys

How to use

Mount the flap disc on an angle grinder following the grinder manufacturer’s instructions and ensure the disc is compatible with the grinder’s speed rating. Hold the grinder with steady pressure and move across the workpiece with overlapping passes, keeping the disc at a slight angle to the surface to achieve effective material removal and avoid gouging. Replace the disc once abrasive performance diminishes or the flange becomes exposed.

Usage recommendations

Wear appropriate personal protective equipment including eye protection, gloves, hearing protection and a dust mask. Use controlled, light-to-moderate pressure to prolong disc life and allow the abrasive flaps to cut efficiently. Avoid excessive side loads and ensure proper cooling intervals when working on thin or heat-sensitive parts.
