The mini chop saws, other than the real high cost enders are made by the same company. They are branded for who ever sells them! I also have the old HF version, got it when they first came out. If you want to cut the brass tubes. You can get the abrasives cut-off disks that fit the Dremel type mandrels they work well. There are also other brands that have the metal saw type blades, that will fit.
They (HF) have a 6" abrasive chop saw, but for the small tubes that are used in pen making the cut kerf is too wide even with a thin cut-off wheel.
