Why Choose the Klingspor SMT 624 Supra?

The SMT 624 Supra is designed for users who require a flap disc that combines:

High Aggression + High Removal Rate + Long Service Life

Klingspor positions the Supra class between its general-purpose Extra products and its highest-performance Special range, providing a strong combination of performance and durability for professional applications. (KLINGSPOR Abrasives)

The SMT 624 is particularly effective for processing:

• Steel

• Stainless steel

• Weld seams

• Edges

• Bevels

• Contoured metal components

Zirconia Alumina Abrasive

The SMT 624 uses:

Zirconia Alumina

abrasive grain. (KLINGSPOR Abrasives)

This abrasive type is well suited to demanding metal grinding applications where aggressive cutting action and useful service life are required.

It makes the SMT 624 particularly appropriate for professional fabrication and maintenance operations involving steel and stainless steel.

P60 Grit

This model uses:

P60 Grit

P60 provides a useful balance between material removal and surface refinement.

Typical applications can include:

• Removing weld material

• Blending welds

• Removing surface imperfections

• Preparing metal surfaces

• Edge processing

• Intermediate grinding

For heavier stock removal, a coarser grit may be preferable, while finer grits can be selected where a smoother finish is required.

125mm Diameter

Each flap disc has a nominal diameter of:

125mm

This makes it suitable for compatible 125mm angle grinders operating within the disc's specified speed limits.

22.23mm Bore

The manufacturer's precise specification is:

22.23mm Bore

often commercially described as approximately 22mm.

The disc must only be fitted to compatible grinding equipment using the correct mounting hardware.

Convex Design

The SMT 624 322774 is manufactured in a:

Convex Form. (Klingspor)

The angled configuration makes the disc particularly effective when processing:

• Edges

• Weld seams

• Bevels

• Chamfers

• Curved or contoured metal surfaces

Australian distributor information describes the SMT 624 as having a 12° convex configuration designed for effective edge grinding. (Southland)

Steel Applications

The SMT 624 is suitable for:

Steel

making it useful for fabrication, structural work, repair and general metal-processing operations. (Southland)

Typical steel applications include weld clean-up, edge preparation and surface grinding.

Stainless Steel Applications

The disc is also specified for:

Stainless Steel. (Southland)

Where stainless-steel contamination control is important, abrasives and tools should be managed according to the organisation's fabrication procedures.

Weld Seam Processing

Weld grinding is a core application for the SMT 624.

The combination of zirconia alumina grain and convex geometry makes it suitable for:

• Grinding weld beads

• Blending weld seams

• Removing excess weld material

• Preparing welded components for subsequent finishing

Klingspor specifically identifies weld grinding as an application for SMT 624 products. (KLINGSPOR Abrasives)

Edge Grinding & Beveling

The convex profile makes the SMT 624 particularly suitable for:

Edge Work and Beveling. (KLINGSPOR Abrasives)

Applications can include:

• Edge preparation before welding

• Chamfering

• Deburring

• Weld-edge blending

• Fabricated component finishing

Maximum 12,250 RPM

For the 125mm 322774 version, Klingspor specifies:

Maximum Speed: 12,250 RPM

and:

Vmax: 80m/s. (Klingspor)

The disc must never be operated above the maximum speed marked on the product.

Always ensure the angle grinder's rated speed is compatible with the abrasive disc.

Box of 10

Klingspor's technical documentation specifies a manufacturer packing unit of:

10 Discs

for catalogue number 322774. (Klingspor)

This listing is therefore configured as:

1 Box × 10 Flap Discs

providing a practical quantity for workshops, fabrication businesses and maintenance teams with regular grinding requirements.

Angle Grinder Compatibility

The SMT 624 is designed for use with appropriate conventional angle grinders. (Mektronics Australia)

Before use, confirm:

• Grinder disc capacity

• Spindle compatibility

• Correct mounting hardware

• Grinder maximum speed

• Guard position

• Disc condition

Never use an abrasive product on equipment that exceeds the disc's rated operating speed.

Safety Considerations

Grinding operations can generate:

• Sparks

• Metal particles

• Abrasive debris

• Noise

• Dust

Appropriate workplace controls and PPE should be selected according to the task.

This may include:

• Safety glasses or goggles

• Face protection

• Hearing protection

• Gloves appropriate to the task

• Protective clothing

• Respiratory protection where required

Always follow the angle grinder manufacturer's instructions and the abrasive manufacturer's safety requirements.

Storage & Handling

To maintain abrasive-disc condition:

• Store in a clean, dry environment

• Protect from excessive moisture

• Avoid crushing or bending discs

• Keep away from excessive heat

• Inspect discs before installation

• Do not use visibly damaged discs

• Keep abrasives in suitable original packaging where practical
