PREMIUM QUALITY STRUCTURE- The whole bench clamp is made of high-quality iron material with high hardness and stiffness. Designed for long-term service time. POWERFUL CLAMPING FORCE- After fine grinding treatment, the surface of the clamp is smooth and flat. Swiveling vise features with the perfectly aligned precision jaw. Maximum clamping force of 19 KN. 360º ROTATING BASE- Swiveling base increases flexibility when in use. This enables the stationary and stability of workpieces, so they wont move even slightly if much force has been applied by the fitter. HIGH ACCURACY SCREW- The screw rod connected with a universal handle is made of high strength material which is not easy to deform, wear resistance, and achieves smooth rotation. WIDE APPLICATION- Precision milling drilling vise, suitable for milling, drilling machine, and precision parts finishing
