Block function: Provides additional hand safety when guiding wood for sawing and cutting - Safety blocks allow you to maintain firm pressure and steadily move the workpiece downwards, without recoil or vibration when the workpiece passes through the cutting blade for sawing. The L-shaped rod (also known as the av push rod) allows you to push the entire workpiece through the blade, and when your space is limited, a standard straight pusher is an ideal choice - both are narrow and useful for handling smaller inventoryApplication: Push blocks are typically used for surface assembly, plywood tearing, wiring, and other woodworking applications, while push rods are typically used in combination with adapters, table saws, wiring tables, and molding machines.
