Roda de carboneto de silício "Koolies" sem calor (vários tamanhos) – Embalagem de 10 unidades

These cut through mild steel like butter and barely warm up, which is exactly what I needed for my bench grinder. The metal bushing keeps them running true with zero wobble, and after a few weeks of steady use the abrasive is still biting. Ten in a pack means I'm set for a long while.

Swapped my old grinding wheels for these silicon carbide ones and the difference in heat is noticeable — no more blue scorching on the edges. They stay sharp way longer too, since the binder keeps exposing fresh abrasive instead of loading up. Ten in a pack at this price is a solid deal.

The metal bushing keeps these spinning true even on my bench grinder, which was my main worry with cheap wheels. They cut fast on mild steel and I didn't notice any heat buildup or clogging during a full session. Ten in a pack at this price is a solid deal.
