Cutting disc for stainless steel DeWalt DT43972 125 x 1.0 x 22.23 mm

DeWalt DT43972 is a 125 x 1.0 x 22.23 mm cutting disc engineered for cutting stainless steel with precision. The disc’s 1.0 mm thin profile minimises material loss and allows fast, controlled cuts when mounted on 125 mm (5") angle grinders. Designed for metalworking and on-site repair tasks, this cutting wheel delivers narrow kerf performance suited to pipe, sheet metal and fabricated stainless applications where clean edges are required.

Advantages

The thin 1.0 mm thickness provides rapid cutting speed and reduced heat build-up compared with thicker discs, helping to preserve material finish. Compatibility with standard 125 mm angle grinders and a 22.23 mm centre hole ensures straightforward mounting and stable operation. The disc is optimised for stainless steel to reduce glazing and extend usable life under normal cutting conditions.

Suitable for

• Cutting stainless steel sheet metal
• Trimming and cutting stainless steel pipes and tubes
• On-site repair and maintenance of stainless fabrications
• Metalworking tasks requiring a narrow kerf and precise cuts

Key specifications

• Diameter: 125 mm (5")
• Thickness (kerf): 1.0 mm
• Centre hole diameter: 22.23 mm
• Intended material: stainless steel
• Tool compatibility: 125 mm angle grinders

How to use

Mount the cutting disc on a compatible 125 mm angle grinder following the grinder manufacturer’s instructions and ensure the disc is seated and tightened correctly. Use appropriate rotational speed limits indicated on the disc and operate the grinder with steady, controlled movements. Apply light to moderate pressure and allow the disc to do the cutting to avoid excessive heat and premature wear. Keep the cut line visible and avoid twisting the disc during engagement to maintain a straight, clean cut.

Usage recommendations

Wear suitable personal protective equipment including eye protection, gloves, hearing protection and respiratory protection when cutting stainless steel. Secure workpieces firmly and use clamps where possible. Allow the disc to cool between extended cuts and inspect for damage before each use. Follow all safety guidelines from the grinder and disc manufacturer.
