FAQ
Frequently Asked Questions (FAQ)
What materials can this grinding wheel be used on?
It is designed for concrete, masonry, brick, granite, stone, marble, mortar, render, and similar hard construction materials.
Will it fit my angle grinder?
Yes. It fits most standard angle grinders with a 22.23mm (7/8") arbor and also includes a reducing ring for 15.875mm (5/8") compatibility.
What does 40/50 grit mean?
A 40/50 grit diamond wheel provides aggressive grinding for fast material removal while still producing a relatively smooth finish.
Can I use this for removing tile adhesive?
Yes. It is excellent for removing tile adhesive, thinset, mortar residue, paint, epoxy, and other coatings from concrete surfaces.
Is it suitable for grinding granite?
Yes. The diamond segments are designed to efficiently grind granite, natural stone, and other hard materials.
Can this wheel be used dry?
Yes. It is suitable for dry grinding. However, allowing the wheel to cool during extended use will help maximise its lifespan.
What is the difference between the 115mm and 125mm versions?
The 115mm (4.5") wheel is easier to control in tighter areas, while the 125mm (5") version covers more surface area and offers faster grinding on larger jobs.
Is this suitable for professional use?
Absolutely. It is designed for professional contractors, builders, tilers, concreters, and serious DIY users who require long-lasting performance.
How long does the grinding wheel last?
The lifespan depends on the material being ground and operating conditions. Thanks to its 5mm diamond segments and premium diamond bond, it is built for extended service life under normal professional use.
What safety equipment should I wear?
Always wear safety glasses, hearing protection, a dust mask or respirator, gloves, and ensure the wheel is securely mounted before use.
