Review on Enhanced Grinding with Astro 219 ONYX Grinder 3 Piece: Unleash the Power! by Elton Luo

Nothing more! They do their job as they should! Advantages: adjustable speed, adjustable exhaust direction. The only downside: the straight grinder doesn't have a rotation switch option, I knew that when I bought it, so it still gets 5 stars. ! It's more of a grinding function to be used as a cutting wheel and costs a bit more money but for this economical set that also comes with decent carbide bits it's worth the price!
