1.Premium Quality Structure: The jaw of the bench vise is made of 45# steel. After high-frequency quenching, the wear resistance of the jaw is improved and the service life is prolonged. The vise body is HT250 high-quality cast iron forging with good toughness, high strength, and durability. 2.Powerful Clamping Force: Vise guide surfaces are finely polished and smooth. When clamping the workpiece, the movement is stable, the positioning is accurate. Jaw Width: 4"" / 10 cm, Jaw Opening: 4"" / 10 cm. The clamping force can reach up to 19 kN, which is suitable for different sizes of goods. 3.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 of high quality and is not easily damaged. The parallelism and perpendicularity are accurate to 0.002"". 4.Humanized Design: Our vises are detachable and can be replaced quickly. The unique downward pressure design protects the workpiece from escaping float when clamped. The hardened swivel handle is a universal joint structure, easy operation, flexible, and convenient to use. 5.Multifunctional Tool: A 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. ******************************************************************************************************* *Specifications Type: Bench Vise Jaw Height: 1.3"" / 3.2 cm Jaw Width: 4"" / 10 cm Jaw Opening: 4"" / 10 cm Max Clamping Force: 19 kN Jaw Material: 45# Steel Body Material: HT250 Gray Cast Iron Wrench Material: QT500 Ductile Iron Vise Height: 3.9"" / 9.8 cm Net Weight: 26.3 lbs / 11.9 kg Item Dimensions(L x W x H) : 12"" x 5.6"" x 3.8"" / 30.5 x 14 x 9.6 cm Package Dimensions (L x W x H): 15"" x 10"" x 6"" / 38 x 25 x 15 cm ******************************************************************************************************* *Pakcage Content 1 x 4"" Bench Clamp Vise 1 x Set of Screws 1 x Set of Nuts 2 x Pads 1 x Manual
