Can this convex grinding wheel be used to remove thick rust on iron or flatten steel weld seams?

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.

What size arbor hole does it have? Will it fit my angle grinder?

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.

Is this grinding wheel flat or convex?

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.

Does it emit strong odors or a storm of sparks?

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.
