Review on Wheel Adapter 28719 Internal Thread by Craig Lovro

On a positive note, without this adapter my 3M 5x3" expander disc would not fit the 5/8" shaft on my Central Machinery bench grinder. However, my bench grinder has one M14 threads, not those 5/8-11 threads like I suspect most bench grinders do, however this adapter fits both of my 5/8 arbor angle grinders (one is Chicago Electric and the other is Black and Decker) This one Adapter is well made and comes with more spacers than you might need The only two cons I've had is that I found an M14 female adapter and a 5/8-11 male adapter that align properly ( Toolocity adapter is NOT, see my review) and that this adapter is very expensive.
