قرص تجليخ معدني 4 1/2 بوصة × 1/4 بوصة × 5/8-11 (80107) صنع في أمريكا أو ألمانيا

Switched from a cheap fiber disc to this metal hub wheel and the difference in smooth grinding is night and day. The 1/4 inch thickness feels solid and cuts through welds without any vibration.

The hub is machined perfectly, no wobble at all on my grinder. I’ve only used one so far on some thick steel, and it held up noticeably better than the cheap discs I was burning through before.

The arbor fit perfectly on my grinder, and this wheel cuts through metal much faster than the generic one I had before. It's noticeably thicker than my last disc, so I expect it to last a good while.
