Buying Guide
Key considerations when choosing a cut off blade for angle grinders include material compatibility, wheel thickness, arbor size, and intended usage. The following questions help match the best blade to your needs.
- What metals will you cut? For carbon steel and stainless, aim for aluminum oxide wheels with robust grain adhesion. Diamond blades excel on very tough materials and longer life.
- What grinder and arbor do you have? Most blades use a 7/8″ arbor; confirm your grinder’s compatibility before purchasing.
- How important is edge life versus speed? Thinner blades cut faster but may wear quicker; consider your balance of speed and longevity.
- Will you cut dry or wet? Some discs are designed for dry use; others tolerate or require wet cutting for heat management.
- Is quantity a factor? Bulk packs save money but require proper storage to maintain abrasive integrity and safety.
- What safety features matter? Look for reinforced fiberglass, shatter resistance, and low-dust designs for healthier workspaces.
FAQ
- Q: Are diamond blades worth it for metal cutting? A: They offer longer life and lower dust in many metal applications, often preferable for repeated cuts on hard materials.
- Q: Can I use these blades on all 4 1/2 inch grinders? A: Most have a 7/8″ arbor and are compatible with common 4 1/2″ angle grinders, but check your model’s arbor size and maximum RPM.
- Q: What thickness should I choose? A: 0.045″ is standard for fast, burr-free cuts; thicker wheels cut slower but may last longer in tough metals.
- Q: How do I maximize blade life? A: Use proper cutting speed, avoid overheating, apply steady pressure, and ensure cooling if cutting hard metals.
- Q: Is a multi-pack better than a single pack? A: Yes for frequent projects; it reduces replacement frequency and ensures you always have a matching blade.
- Q: Are there safety concerns with these blades? A: Always use a proper guard, wear eye protection, and inspect for cracks or damage before use.
