Abrasive hook-and-loop sanding disc KLINGSPOR 125 mm, grit K40, zirconia alumina, pack of 50

KLINGSPOR abrasive hook-and-loop sanding discs, 125 mm diameter with coarse K40 grit made from zirconia alumina, are engineered for heavy stock removal and fast material removal on metal, steel and hard wood. The hook-and-loop (velcro) backing ensures quick disc changes on compatible backing pads and angle grinders. Supplied as a pack of 50, these discs support continuous workshop use and reduce downtime during large grinding and surface-preparation tasks.

Advantages

These 125 mm zirconia alumina discs combine high cutting performance with enhanced durability for demanding surfaces. The coarse K40 grit offers aggressive removal rates while maintaining disc life under high-pressure and high-temperature conditions. The hook-and-loop fastening allows rapid replacement and secure attachment to standard 125 mm backing pads, increasing productivity in professional metalworking and carpentry environments.

Suitable for

• Heavy stock removal on steel and ferrous metals
• Shaping and leveling of hard wood
• Rust and weld seam removal
• Surface preparation before painting or coating
• Use with 125 mm angle grinders and matching backing pads

Key specifications

• Disc diameter: 125 mm
• Abrasive grain: zirconia alumina
• Grit size: K40 (coarse)
• Attachment: hook-and-loop (velcro) backing
• Pack quantity: 50 discs
• Intended materials: metal, steel, hard wood

How to use

Mount the sanding disc onto a compatible 125 mm backing pad with a hook-and-loop surface while the power tool is switched off and unplugged or the battery removed. Ensure the disc is centered and firmly attached before powering the tool. Use light to moderate pressure and steady movements to allow the zirconia alumina abrasive to cut efficiently; excessive pressure can shorten disc life and overload the tool. For best results on metal, maintain consistent motion along the workpiece and avoid dwelling in one spot.

Usage recommendations

Wear appropriate personal protective equipment including eye protection, gloves, and respiratory protection when grinding metal or wood. Use the discs on tools whose maximum speed rating matches or exceeds the disc's rated RPM, and replace discs that show significant wear, tear or damage to prevent unsafe operation.
