12" × 1 1/2" × 5" ثقب نورتون عجلة طحن بيضاء

Finally got this mounted on my 5-inch arbor and the 12-inch diameter is perfect for heavy grinding without overheating the steel. The A46 grit takes off material fast but leaves a surprisingly clean edge.

The A46 grit is noticeably finer than the 36-grit wheels I've used before, and it leaves a much smoother finish on my HSS lathe tools. It runs perfectly true right out of the box with no vibration at all.

That 12-inch wheel with the 5-inch arbor fit my grinder perfectly, and the 1 1/2-inch thickness gives it real heft for steady work. The white A46 grit cuts cleanly without loading up, and I've already run it through a dozen tool edges with no wobble.
