Grinding Disc Fiskars D.125 L-shape, abrasive cutting/grinding accessory for angle grinders

The Fiskars Grinding Disc D.125 L-shape is an abrasive accessory for 125 mm angle grinders designed to perform both cutting and grinding operations on metal and other hard materials. Its L-shaped profile creates a focused abrasive edge that facilitates surface preparation, weld removal, deburring and light cutting in workshop, fabrication and construction environments. The disc fits standard 125 mm grinders and is intended for tasks that require controlled material removal and a narrow cutting or grinding line.

Advantages

The L-shaped geometry concentrates abrasive force at a narrow edge for precise grinding and controlled cutting. The disc combines cutting and grinding functionality in a single accessory, reducing the need to change discs frequently. Its construction delivers consistent abrasion for surface preparation and weld dressing while being compatible with commonly used 125 mm angle grinders in professional and DIY settings.

Suitable for

• Surface preparation and paint or rust removal from metal
• Weld seam grinding and smoothing
• Deburring edges and removing burrs after cutting
• Light cutting operations on thin metal sheets or profiles
• General workshop and maintenance metalwork tasks

When it may not be suitable

This disc is intended for light to medium-duty grinding and cutting on metal and similar hard materials; it is not designed for heavy structural cutting or prolonged removal of large volumes of material. For masonry, concrete cutting, or specialized abrasive finishes, use discs specifically designed for those materials. Always match disc type and grit to the material and task to avoid suboptimal performance.

Key specifications

• Diameter: 125 mm
• Profile: L-shaped abrasive edge for combined cutting and grinding
• Compatible with: 125 mm (5") angle grinders
• Intended materials: metal and other hard materials (not for masonry-specific use)
• Primary uses: surface preparation, weld removal, deburring, light cutting

How to use

Mount the disc on a properly guarded 125 mm angle grinder following the grinder manufacturer’s instructions and ensure the disc is compatible with the grinder’s RPM. Securely tighten the fastening nut and check the disc for damage before use. Operate the grinder with steady, controlled motions, applying light to moderate pressure and allowing the abrasive surface to do the work. Keep the disc angle and contact point consistent for uniform results, and stop periodically to inspect progress and avoid overheating the workpiece.

What to consider before purchase

• Ensure the disc diameter and arbor fit a 125 mm angle grinder and that RPM rating matches your tool
• Confirm the disc type is suitable for metal and the specific tasks you plan (grinding, weld removal, deburring, light cutting)
• Assess whether an L-shaped profile is appropriate for the required edge access and cutting line width
• Consider personal protective equipment needs such as eye protection, gloves and hearing protection

Usage recommendations

Use eye and face protection, gloves and hearing protection when operating the grinder. Start with light pressure and increase only as needed, maintain steady angles, and allow the disc to cool between extended passes. Replace the disc if it shows signs of cracking, significant wear or imbalance to maintain safe and consistent performance.
