DX8, DX6 and DX4 vises were designed using Finite Element Analysis—providing 30% less horizontal push-back deflection than previous DX models. Less vise-body deflection translates to more stability and a lifetime of dimensional precision—setting a new standard in precision flatness, parallelism and repeatability. The DX8 CrossOver® vise features the same bed height and keyway to the stationary jaw face as the D810. The DX8 also features a redesigned nut with less weight, a new brush seal design, and a larger stronger bearing pack for more durability.
