Grinding disc DeWALT DT20540-QZ Flat centre for Iron Metal Stainless steel

The DeWALT DT20540-QZ grinding disc with a flat centre is designed for cutting and grinding iron, metal and stainless steel. Supplied in packs of 100, this accessory is intended for professional and DIY metalworking tasks where consistent material removal and precise edge work are required. The disc's flat-centre profile provides stable contact during cutting and grinding operations and is compatible with common angle grinders used in metal fabrication and repair.

Advantages

The flat centre design ensures even pressure distribution and predictable contact with the workpiece, reducing the risk of uneven cuts. Manufactured for metalworking applications, the disc delivers durable abrasive performance on iron, non-alloyed metals and stainless steel. Supplied in bulk packs of 100, it supports continuous work without frequent reordering and offers consistent dimensions for reliable mounting and balanced rotation.

Suitable for

• Cutting and grinding iron components
• Shaping and removing material from steel and stainless steel
• Metal fabrication and repair tasks
• Workshops and construction sites requiring high-volume consumables

Key specifications

• Disc profile: flat centre
• Material application: iron, steel, stainless steel
• Pack quantity: 100 discs per pack
• Compatibility: standard angle grinders for metalworking
• Intended use: cutting and grinding

How to use

Mount the disc on a compatible angle grinder following the tool manufacturer's instructions and ensuring the grinder is switched off and disconnected from power before fitting. Use appropriate clamping flanges to secure the disc and check for runout or visible damage before starting. When operating, maintain steady pressure and a controlled cutting or grinding angle suited to the flat-centre profile, and allow the abrasive to do the work rather than forcing the disc through the material.

Recommendations

Always wear appropriate personal protective equipment including eye protection, hearing protection, gloves and respiratory protection when working with metal grinding discs. Observe the maximum safe operating speed of your angle grinder and follow safe work practices: secure the workpiece, maintain a firm two-handed grip on the tool, and avoid side-loading the disc. Store discs flat in a dry area away from direct heat or humidity to preserve abrasive performance.
