Joshua F. ★★★★★

Had to swap out the old wheel mid-project and this 4-inch one with the 1/4-inch shank seated perfectly in my grinder. The 3600RPM rating is spot-on for what I need, and the A60 grit chews through welds without bogging down. Used it for about an hour straight and it held its edge nicely.

Ellie ★★★★★

The grey wheel's A60 grit has been tearing through my workpieces with zero loading, and it's held its shape nicely across a full afternoon of use. Spins smooth at 3600 RPM, no vibration wobble that I can feel.

Hannah ★★★★★

The 1/4-inch shank fits my drill chuck perfectly, and the grey wheel cuts through mild steel without loading up. At 3600 RPM it’s smooth enough for a few minutes of continuous work, though I keep the pressure light.
