Exquisite craftsmanship vise: The whole vise is made of 20CrMnTi material with quenching treatment, the hardness can reach 58-62HRC, and the unique structure can make the workpiece strongly clamped. Fine grinding: the precision of each working surface is 0.003mm, and all four surfaces can be used with pressure plate to stabilize it on the working table, and the surface roughness is up to 0.8UM. Strong clamping force: high-temperature quenching treatment of carbon steel material, high toughness, impact resistance, clamping force, can be very firmly fixed workpiece, V-groove jaws non-slip treatment, clamping tighter and more stable. Large clamping force: Screw diagonal pull type, large clamping force, can easily adjust the size of the clamped workpiece, wide range of adjustment, can be used by more than one unit at the same time. WIDE APPLICATION: It can be used for woodworking, cutting conduit, drilling, metal working, sanding or planing, sawing and so on. It can be easily and quickly mounted or dismounted to various workbenches., Weight: 3.968320716 pounds, Manufacturer: XiaoLuBi
