Smooth Guide Rails: The guide rail surface is finely ground, achieving a parallelism of 0.1mm, resulting in an exceptionally smooth and flat surface. This ensures more precise contact with the workpiece and smooth, jam-free movement. Superior Structure: The entire vise is constructed from high-hardness, high-rigidity premium iron. It provides strong clamping force, is not easily moved, and is easy to use. Flexible Handles: The handles rotate naturally and smoothly. To achieve production precision, the contact surfaces are finely polished, greatly reducing jamming during use, and jaw adjustment is easy and convenient. This heavy-duty cross-slide drilling machine vise is designed specifically for woodworking and metalworking, and is widely used in milling machines, drilling machines, and machinery repair.
