The Super Shaft is engineered to stand the test of time, and machined out of polished & ground 4142 chromoly steel, made in the USA. The Swag Super Shaft easily allows you to switch from one hole saw to the next with the use of threaded arbors shown above and sold HERE.
You no longer need to jam screw drivers in the port holes to remove your hole saws and or use thread reducers in your hole saws to get the correct thread diameter. You will no longer be breaking screwdrivers, ob-longing your hole saws, and or breaking and welding the thread reducers on your hole saws, do the math and save your self the aggravation.
We have found that it works best to permanently leave the arbor inserts in your hole saws. To remove the arbors from the shaft you simply loosening the 3 sets screws, this cuts down on having to thread/unthread the hole saw and potentially galling up the threads on your hole saws.
