• “H” indicates the adjustment length with an adjusting screw • In case the projection length needs to be adjusted from the shank side, add the letter “W” to adjusting screw model number for hexagon sockets on both sides

Use only cutting tools that have a shank tolerance of h6 (see table pg. 26). Do not use with cutting tools made with a flat on the shank (ie: Weldon type shank). Roughing end mills are not recommended for use with hydraulic chucks. Do not tighten the clamping screw without first inserting a cutting tool into the tool holder. Always insert the cutting tool into the hydraulic tool holder beyond min. clamping length “E”. ! CAUTION
