Made from sturdy, cast iron construction, the Ratcheting Arbor Press from Palmgren features a removable machined steel anvil with four slot positions. The arm provides an optimal leverage position with a consistent application of force. It also offers more clearance over the table for broaching and pressing large items. It is counterweighted for rapid handle return. The rugged steel ram, driven by a machined pinion, is reversable with one end solid and the other end has a hole and magnet to hold bits and tools.

Shaft used for rotary support in machining applications. In grinding, the spindle for mounting the wheel; in milling and other cutting operations, the shaft for mounting the cutter.
Operation in which a cutter progressively enlarges a slot or hole or shapes a workpiece exterior. Low teeth start the cut, intermediate teeth remove the majority of the material and high teeth finish the task. Broaching can be a one-step operation, as opposed to milling and slotting, which require repeated passes. Typically, however, broaching also involves multiple passes.
Space provided behind a tool’s land or relief to prevent rubbing and subsequent premature deterioration of the tool. See land; relief.
