Single wheeled versus two-wheeled – The simplicity of the single-wheeled Tradesman Machinist is a great choice if you’re using it for a few end mill operations, including necks, flats, rads and cut off. All these operations can be carried out on one side of the machine and changing set ups only requires changing grinding wheels (which is easy with only one screw securing the wheel cap).
Choose the dual-wheeled Tradesman Machinist if you want to set up on the other side for lathe tools, countersinks, general purpose HSS grinding or belt sanding (2″ and 4″ belt sanders can be mounted to either side as well). Another example is V-Block for flats on one side and ER32 Tool Holder on the other for necks and cut off.
The single-wheeled Tradesman has the wheel at the operators right hand. The V-block can be mounted on the left or right hand side and T-ER32 Tool Holder can be purchased as left or right hand (left-hand is mounted on the operators left side and right-hand, on the right).
