Review on USA Polishing Supply Grinder Extender by Joe Garczynski

Although the description correctly lists a 5/8"-11 thread pitch, every 5/8" angle grinder and bench grinder I've ever used has the same shaft threads. THIS PRODUCT HAS DIFFERENT THREADS - no doubt useful for other customers. But before you order, check your carving! The standard 5/8" grinder thread has a pitch of 13, not 11. It doesn't fit standard grinders. I think Renegade Products could have made this a bit clearer, which is why I'm giving it a three-star neutral rating. Gave evaluation The product was good and you are welcome to buy it after confirming the thread pitch!
