This is a 5-piece set of 125mm cutting discs for your angle grinder. They cut through different metals, such as iron and steel. The resin bond is reinforced. This lets you use them at fast speeds. The thin profile helps you make quick, accurate cuts. Features and Benefits
- Reinforced resin bonding - Two layers of fiberglass mesh make the disc strong and stable.
- Thin 1.2mm profile - It cuts faster. There is less friction and less material waste than with thicker wheels.
- 22.23mm bore size - This fits the shaft of any standard 125mm (5-inch) angle grinder.
- Abrasive for metal - It is made to cut through materials like mild steel, rebar, and stainless steel. Applications
- Cutting metal studs, pipes, and tubing to length.
- Slicing through sheet metal for making or fixing things.
- Removing old bolts or trimming rebar at a job site.
Step 1: Mount the Sanding Disc to the Mandrel
The 125mm grinding and sanding discs in this 5-piece set are designed for use with angle grinders. While these discs are not Dremel brand, the general principles for mounting sanding discs to a mandrel apply. Ensure your angle grinder is unplugged before attempting to attach any accessories. The discs are circular saw blade and grinding disc types, suitable for cutting metal, wood, iron, and steel bar. Always confirm the disc's maximum RPM rating matches or exceeds your angle grinder's speed to prevent accidents and ensure optimal performance.
Option A: Standard Screw Mandrel (402)
When using a standard screw mandrel, align the central hole of the 125mm grinding or sanding disc with the screw on the mandrel. Secure the disc firmly by tightening the screw, ensuring it is flush and centred. This method provides a reliable attachment for the resin-material discs. Always double-check that the disc is securely fastened before operating your angle grinder. Improper attachment can lead to the disc coming loose during use, which is a significant safety hazard.
Option B: EZ Lock Mandrel (EZ402)
While this specific 5-piece set does not specify compatibility with an EZ Lock mandrel, the general principle involves a quick-change mechanism. If your angle grinder uses an EZ Lock system, you would typically pull back the spring-loaded collar, insert the disc, and then release the collar to lock it in place. For these 125mm resin discs, ensure the central arbor hole is compatible with your angle grinder's specific quick-change system. Always verify the disc is fully engaged and locked before starting work.
Step 2: Insert the Mandrel into Your Dremel
The 125mm grinding and sanding discs in this 5-piece set are designed for angle grinders, not Dremel tools. Dremel tools typically use smaller diameter accessories and different mounting systems. To use these discs, insert the mandrel (with the disc attached) into the chuck of your angle grinder. Tighten the chuck securely using the appropriate spanner or key. Ensure the disc is perfectly centred and no wobble is present. Check that the disc's rotational direction matches the arrow on your angle grinder for safe operation.
Step 3: Best Practices for Sanding
When using these 125mm grinding and sanding discs, always wear appropriate personal protective equipment, including eye protection, gloves, and hearing protection. These resin discs are suitable for metal, wood, iron, and steel bar cutting. Apply consistent, light pressure to avoid overheating the material and the disc. Excessive pressure can cause premature wear and potential damage. For general sanding, an 80 grit disc is good for material removal, while a 220 grit would be used for finer finishing. Monitor disc wear; replace the disc when it becomes dull or damaged.

Q: How long do these typically last when cutting something like rebar? A: The lifespan depends on the material's thickness and hardness. For something like 1/2-inch steel rebar, you can generally expect to get a good number of clean cuts from a single disc before needing to change it..
