The D810 vise has a big 10 inch jaw opening, the largest in this class. That's a 33% increase in capacity from the D80 vise. The D810 offers greater flexibility in precision part clamping. A very important feature of the D810 vise is its similarity to the D80 vise. If you already have D80 vises in your shop the D810 matches up with the same height and distance of the keyway to the stationary jaw as the D80.
