Review on 🔧 SPTA Stainless Steel Rotary Extension Shaft Set - 75mm, 100mm, and 140mm, 5/8"-11 Thread - Perfect for Rotary Polisher, Car Polisher, Polishing Pads, Backing Plate Electric Polisher by Jeff Labore

Although listed in the frequently purchased box on the Mini Buffer page, they will not fit the M14 thread on the output shaft as they are 5/8-11 on both ends - have thread. You will need to adjust M14 on the machine to >5/8-11 and then on the skid plate back to 5/8-11->M14 if using the skid plates that come with the mini bumper. As a side note, these extension shafts fit the output shaft of my 4-1/2" Bosch variable speed grinder without an adapter. (You will still need a 5/8-11 female-to-M14 yoke adapter on the base plate to use M14 inserts)
