CAUTION
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”.
