عجلة تجليخ ماسية حلزونية ملولبة 4-1/2" × 5/8"-11

I had a lot of concrete to grind down for a paver project, and this 4-1/2" cup wheel with the 5/8-11 arbor fit my angle grinder perfectly. It cut through the hard surface smoothly without bogging down, and I was impressed by how much material it removed before showing any wear.

The 7mm seg height on this wheel chews through concrete far faster than my old flap disc, and the 5/8-11 arbor fit my grinder with zero wobble. I’ve run it for a solid afternoon of edging and it barely even looks worn.

I was skeptical about how well a diamond cup wheel would clean up rough concrete, but the 7mm segment height chewed through high spots way faster than my old grinding stone.
