Buying Guide: 220 Grit Grinding Wheels And Accessories
- What is 220 grit best for?
- Balance between material removal and surface finish. Ideal for finishing welds, smoothing edges, and prepping metal surfaces for painting.
- Wheel type considerations:
- Aluminum oxide discs and flap discs offer good value and broad metal compatibility. Diamond wheels excel at hard materials like stone and glass but cost more.
- Shape and compatibility:
- Bevel Type 27 or Type 29 flap discs affect edge access and surface contact. Ensure arbor size matches your grinder.
- Safety and maintenance:
- Inspect discs for wear, avoid overheating, and use proper PPE. Replace worn discs promptly to maintain performance and safety.
- When to choose diamond or specialized wheels:
- Diamond wheels are best for gem, marble, and glass; aluminum oxide is typically sufficient for most metalwork tasks.
FAQ
- Q: Can I use 220 grit wheels for heavy stock removal?
A: They can remove material, but for heavy stock removal, consider lower grit (e.g., 80-120) for faster material removal and then refine with 220 grit. - Q: Are flap discs safer than bond wheels?
A: Both require proper mounting and guards. Flap discs distribute material removal more evenly, potentially reducing gouging when used correctly. - Q: What grinder arbor size is common for these discs?
A: Most 4 1/2 inch discs use 7/8 inch arbors, but always verify your grinder’s arbor size before purchase. - Q: How do I prevent disc shedding and heat buildup?
A: Use light to medium pressure, let the wheel do the work, and pause to cool if you notice excessive heat or glazing. - Q: Is a diamond wheel worth it for metal finishing?
A: Diamond wheels excel on hard materials; for most metal finishing, aluminum oxide discs are cost-effective and perform well. - Q: Which product is best for welding seam finishing?
A: SI FANG 240 Grit flap discs are designed for bevel grinding and weld seam finishing with Type 29 geometry for edge access.
