Abrasive flap discs KLINGSPOR 125 mm Ø, grit 40, with holes, pack of 5 (MPN 45293)

Klingspor abrasive flap discs, 125 mm diameter with grit 40 in a pack of five, are designed for use on angle grinders for aggressive material removal and surface preparation on metal and steel. The discs combine overlapping abrasive flaps with a perforated backing to improve cooling and dust extraction during operation. They are intended for tasks such as rough grinding, deburring and weld seam removal in workshops, fabrication shops and construction sites.

Advantages

The flap disc construction provides consistent contact with the workpiece, delivering controlled material removal and a uniform finish without deep gouging. The 125 mm size and coarse 40 grit offer efficient stock removal while the perforated design helps dissipate heat and reduces clogging from metal particles. Supplied as a pack of five, the discs support repeated grinding tasks and minimize downtime for disc changes.

Suitable for

• Rough grinding of steel and ferrous metals
• Deburring edges after cutting or machining
• Removing weld seams and scale
• Prepping surfaces for painting or coating
• General metal fabrication and maintenance work

Key specifications

• Disc diameter: 125 mm
• Abrasive grit: 40 (coarse)
• Perforated backing for improved cooling and dust extraction
• Flap-style abrasive arrangement for progressive wear and consistent finish
• Suitable for use on angle grinders
• Pack quantity: 5 discs

How to use

Fit the 125 mm flap disc securely to an angle grinder sized for this diameter following the grinder manufacturer’s safety and mounting instructions. Operate the grinder at the recommended speed range for the disc type, applying steady, even pressure and moving across the workpiece to achieve uniform material removal. Allow the abrasive flaps to do the cutting rather than forcing the tool; excessive pressure can reduce disc life and increase heat. Replace discs when abrasive performance diminishes or when damage to the backing or flaps is visible.

Usage recommendations

Use appropriate personal protective equipment including eye protection, gloves and hearing protection. Ensure proper dust extraction or ventilation when grinding metal to limit exposure to metal dust. Match the Q-angle and speed rating of the angle grinder to the disc specifications and avoid side-loading beyond the disc’s intended use.
