## Questions & Answers

**Q: Can this convex grinding wheel be used to remove thick rust on iron or flatten steel weld seams?**
A: Yes. While it excels at granite shaping, the vacuum brazed tech and #30/40 grains allow this convex disc to effortlessly grind heavy rust, zinc coatings, and tough steel welds without clogging. Perfect for mixed-material jobsites.

**Q: What size arbor hole does it have? Will it fit my angle grinder?**
A: It features a universal 7/8"(22.23mm) arbor to fit standard grinders. Note: The 4" disc includes an extra washer to fit 5/8" spindles too. Please select your matching disc diameter (4", 4.5", or 5") based on your grinder guard size.

**Q: Is this grinding wheel flat or convex?**
A: It has a unique convex (curved "flying saucer") profile. Unlike flat wheels, this convex shape gives you maximum control for stone grooving, curved contouring, artistic carving, and smoothly shaving down uneven surfaces.

**Q: Does it emit strong odors or a storm of sparks?**
A: No. Compared to ordinary resin wheels, our vacuum brazed diamond technology drastically reduces friction. This results in significantly fewer sparks, cooler grinding, and absolutely no harsh odors—making your workspace safer.
