Cutting Disc for Metal KLINGSPOR 356×4.0×25.4 mm A924SX Special for Railway Rails

KLINGSPOR cutting disc A924SX Special, size 356×4.0×25.4 mm, is engineered for cutting heavy-duty metal such as railway rails, thick steel beams and other large profiles. The abrasive composition and reinforced construction enable consistent material removal and stable cutting performance when used with compatible angle grinders or portable cutters featuring a 25.4 mm bore. The disc is intended for demanding industrial and maintenance environments where precision along with high cutting speed is required.

Advantages

The A924SX Special disc delivers high stock removal and prolonged service life due to its optimized abrasive blend and bond. Its robust build reduces vibration and wobble during cutting, improving operator control and straightness of the cut. The 4.0 mm thickness balances cutting speed with structural stability for large-section steel, while the 25.4 mm centre hole ensures compatibility with common grinder spindles. The disc’s formulation is suitable for continuous, on-site rail maintenance and heavy fabrication tasks.

Suitable for

• Cutting railway rails and hardened steel tracks
• Severing thick steel profiles, beams and plates
• On-site rail maintenance and repair work
• Heavy fabrication and dismantling of structural steel

Key specifications

• Diameter: 356 mm
• Thickness: 4.0 mm
• Bore (centre hole): 25.4 mm
• Abrasive type: high-performance metal-cutting abrasive (A924SX Special)
• Construction: reinforced cutting wheel for heavy-duty applications

How to use

Mount the cutting disc on an angle grinder or portable cutter with a 25.4 mm spindle, following the tool manufacturer’s mounting instructions and ensuring the disc is compatible with the grinder’s maximum speed (RPM). Securely tighten the flange nut, use appropriate guards, and position the workpiece on a stable support. Make steady, controlled passes through the material without applying excessive lateral pressure; allow the abrasive to do the cutting. Replace the disc if signs of excessive wear, cracking, or imbalance appear.

Usage recommendations

Always wear suitable personal protective equipment including eye protection, hearing protection, gloves and protective clothing. Use appropriate respiratory protection if cutting produces visible dust or fumes. Verify that the disc’s maximum operating speed matches or exceeds the grinder’s speed. Store the discs flat in a dry place away from extreme temperatures and humidity to preserve performance.
