Cutting Disc for Metal KLINGSPOR 300 x 3.0 x 32 mm A24R Supra (model 6807)

A KLINGSPOR metal cutting disc 300 x 3.0 x 32 mm A24R Supra is designed for abrasive cutting of steel and other ferrous metals. With a 300 mm diameter and 3.0 mm thickness, this cutting wheel offers a practical balance between fast cutting speed and acceptable edge life. The 32 mm bore fits common flange systems used on stationary and portable cutting machines in metal workshops and fabrication environments.

Advantages

The A24R Supra abrasive grit and resin-bond construction deliver consistent cutting performance on hard materials while maintaining dimensional stability during use. The larger 300 mm diameter enables deeper cuts and longer service intervals per wheel compared to smaller discs. A 3.0 mm thickness reduces material loss and sparks during cutting, while the reinforced structure helps resist cracking under typical workshop stresses.

Suitable for

• Cutting structural steel and profiles
• Fabrication of metal parts and assemblies
• Cutting round bars, pipes and sheets
• Use on fixed and portable cutting machines in workshops

Key specifications

• Diameter: 300 mm
• Thickness: 3.0 mm
• Bore size: 32 mm
• Abrasive grade: A24R (Suprа grain, medium-coarse)
• Bond type: resin-bonded abrasive
• Intended material: steel and ferrous metals

How to use

Mount the cutting disc on a compatible machine with a 32 mm arbor and ensure flanges and guards are correctly fitted. Check the disc for visible damage before installation and confirm that the machine speed does not exceed the disc’s rated peripheral speed. Use steady feed and avoid excessive side pressure; allow the disc to cut through the material at a controlled pace. Wear appropriate personal protective equipment and follow machine manufacturer instructions during operation.

Usage recommendations

Store discs flat in a dry environment and keep them away from significant temperature fluctuations or direct moisture. Replace the disc if you detect cracks, chipping, or signs of delamination. For best results on thicker sections, use the 300 mm diameter to reduce the number of passes, and consider matching disc thickness and machine type to workpiece geometry to optimise cutting accuracy and wheel life.
