Key Features:

【PREMIUM QUALITY STRUCTURE】 - 45# steel jaws, after high-frequency quenching, undergo improving the jaws' wear resistance and service life. Vise body for the HT250 high quality cast iron forging, which has good toughness, high strength, and durability.
【POWERFUL CLAMPING FORCE】 - Vise guide surfaces are finely polished, smooth surface. When clamping the workpiece, the movement is stable, the positioning is accurate, and the clamping force can reach up to 19 KN, which is suitable for workpieces of different sizes.
【HIGH ACCURACY SCREW】 - The closed design protects the screw rod and prevents the entry of iron pins and other debris convenient for maintenance and cleaning. Our screw is made of high-strength materials and is not easily damaged. 
【HUMANIZED DESIGN】 - Our vises are detachable and can be quickly changed. The unique downward pressure design prevents the workpiece from floating when clamped. The hardened swivel handle is a universal joint structure, easy operation, flexible, and convenient to use.
【MULTIFUNCTIONAL TOOL】 - Jaw Width: 4" (100 mm), Jaw Opening: 4" (100 mm). Milling Vise is an essential tool for fitters. Most of the fitters' work is running by using the clamping vise such as sawing, filing, chiseling, and some assembly and removal jobs.

4" Precision Lock Down Vise
During workshop operation, many workpieces minor damage due to their materials or excessive force, which caused work delays or economic losses. Therefore, to avoid damage to your workpiece, we recommend that you use the vise to clamp the workpiece. Our vise has a strong clamping force and can hold the workpiece very firmly. It can ensure the stability of the workpiece and avoid damage.

Wide Application
Precision milling vise is the main accessory of precision milling machine and NC/CNC machine tool. Suitable for finishing milling machines, drilling machines, and precision parts.

Precision Design
The guide rail surface is refined ground, seamless contact surface, and the positioning is more accurate. The semi-circular ball has a vertical downward pressure to keep the workpiece stable and prevent it from floating.

Adjustable Handle
The universal joint handle is ductile iron material, which is not easy to rust and is flexible and durable. You can precisely adjust the jaws' gripping force through the handle and complete the workpiece clamping work excellently.

Quality Lead Screw
The thread pitch of the ladder screw is larger than the standard screw. The surface is quenched, turned, and ground. It is more wear-resistant, durable, and corrosion-resistant than the ordinary screw and has higher accuracy.

Hardened Clamping Jaw
The jaws are thickened and finely ground, and the maximum clamping force can reach 19 KN. The lockdown vise machine adopts a fully enclosed design, and iron filings are not easy to enter, which improves the service life of the vise.

Durable Material
The vise is made of HT250 high-quality cast iron, with strong toughness, high tensile strength, and wear resistance. Internal refine grinding treatment, smooth use, no jamming, rust, and corrosion resistance.
