Why Choose Klingspor A 24 R Supra?

The A 24 R Supra is designed for professional grinding where users require:

High Aggressiveness + Strong Service Life + Reliable Steel Grinding Performance

Klingspor describes the product as having an optimised recipe for steel, while also allowing use on stainless steel and castings. (Klingspor)

This makes it a versatile workshop grinding wheel for organisations working across multiple ferrous-metal applications.

Aluminium Oxide Abrasive Grain

The A 24 R Supra uses:

Aluminium Oxide

abrasive grain. (Klingspor)

Aluminium oxide is a widely used abrasive for ferrous metals and provides robust cutting action for demanding grinding applications.

6mm Grinding Thickness

The wheel is:

6mm Thick

which distinguishes it from thin cutting-off wheels.

The additional thickness provides the structure required for:

• Side grinding

• Weld removal

• Edge grinding

• Surface stock removal

• General-purpose metal grinding

This wheel is intended for grinding rather than narrow cut-off work.

125mm Diameter

Each wheel measures:

125mm Diameter

making it suitable for compatible 125mm angle grinders operating within the specified maximum speed.

22.23mm Bore

The exact manufacturer bore specification is:

22.23mm. (Klingspor)

Commercial product titles may round this to:

22mm

or:

22.2mm

but 22.23mm is the precise Klingspor dimension.

Depressed Centre Form G

Catalogue number 13402 is supplied in:

Form G

which is Klingspor’s depressed-centre grinding-wheel configuration. (Klingspor)

This shape provides clearance between the grinder spindle assembly and the work surface during side grinding.
