If you’ve ever found yourself standing over a concrete floor wondering why your diamond grinding shoes are either cutting too aggressively or leaving behind a dull finish, you’re not alone! Selecting the right grit size is essential for efficient, high-quality grinding. Whether you’re prepping a concrete floor for polishing, removing old coatings, or simply smoothing out imperfections, your grit choice will make all the difference.
Here’s a simple guide to help you choose the correct grit size for your next concrete grinding job.
🔎 What Is Grit Size, and Why Does It Matter?
Grit size refers to the particle size of the abrasive diamonds in your grinding tool. It directly influences:
✅ Material removal rate (how fast the tool cuts)
✅ Surface finish (how smooth or rough the surface becomes)
✅ Tool lifespan (finer grits tend to wear faster on aggressive jobs)
Think of it like sandpaper—coarser grits cut faster but leave scratches, while finer grits leave a smoother surface.
🏗️ Choosing the Right Grit for Concrete Grinding
Here’s a quick guide to choosing the correct grit size based on the task:
1️⃣ Coarse Grinding (Grit 16–30)
Ideal for:
- Removing thick coatings like epoxy, glue, or paint.
- Grinding down high spots or rough concrete.
- Initial surface prep.
👉 Try Cutting Edge Diamond Tools’ Coarse Grinding Shoes with aggressive segments for fast removal. They’re designed to fit Husqvarna Shark models and compatible grinders, giving you both power and precision.
2️⃣ Medium Grinding (Grit 40–60)
Perfect for:
- Light coating removal.
- Smoothing rough concrete.
- Preparing the surface for polishing.
💡 Use our medium grit grinding shoes, known for balancing cutting power and surface finish. They’re great for general-purpose grinding and leave a smoother surface, reducing the time spent on finer grit passes.
3️⃣ Fine Grinding and Polishing (Grit 80–120)
Best for:
- Final surface preparation before polishing.
- Light surface smoothing and defect removal.
- Preparing for resin-bond polishing steps.
✨ Our fine-grit grinding shoes (available in multiple bond options) leave a clean, ready-to-polish surface with minimal scratches, saving you time and money on subsequent steps.
🤝 Pro Tip: Let the Floor Guide You!
- Hard concrete? Use a softer bond shoe with coarser grit to cut effectively.
- Soft concrete? Opt for a harder bond and medium to fine grit to prevent glazing.
