The Swag Super Shaft is an exceptional upgrade for your JD² TN100, JD² Notchmaster, Pro Tools HSN tubing notcher and or the Baileigh TN-250 tube notcher, or any tubing notcher that has a shaft diameter of .75", 1.00" or 1.25" OD. This upgrade is a vast improvement over the existing sub par designs that are currently in the market place.
The Super Shaft is engineered to stand the test of time, and machined out of polished & ground 4140 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. We recommend using Milwaukee Hole Saw Arbors as they seem to have the tightest tolerances.
NOTE: Due to variations in the bore dimensions of your bearing block, your needle bearings may be slightly constricted. This can make it difficult to insert your shaft. Make sure to pack your bearings with grease and push all of the needles up into the cage. If your shaft still will not fit, chuck it up into your drill and spin it while pushing it into the bearings.
