Shank Tolerance of SBT / PBT A positive tolerance (0.1 - 0.3) is applied to the shank height (H) to prevent the cutting edge from interfering with the toolpost. Tool Overhang
Shank height ( H ) is greater than cutting edge height ( HF ). Toolpost
Amount of tool overhang can be shortened when mounted on a toolpost.
