The vice can be rotated 360 degrees even when fixed to the workbench, and can be fixed at any angle you like. The internal processing of the main unit has been brooched, which means less lossing load and a greater tightening force. Parts are made of strong cast iron and tag tiles that are resistant to breakage and durable. Easy to refuel, smooth operation. Heat treated base for durability, replaceable and longer vice life. The handle stopper is headed to keep it from falling out.
