SHANK TYPE CUTTERS
These are primarily designed for cutting internal gears, splines and serrations, both spur and helical. May also be designed for externals if required. These cutters are full form generated however small the pitch circle diameter (PCD) although strength of the cutter produced is the limiting factor. The strength and rigidity of shank type cutters is greatly improved by the Dathan ribbing method and is especially advised for those of small PCD.

HUB TYPE CUTTERS
Dathan hub type cutters are designed for cutting internal components where maximum rigidity is required. Hub type cutters are recommended for cutting long face widths or for coarse pitches.
In general terms, any tooth form, face width or number of teeth that is available on a shank cutter, can be manufactured with a hub type fitting. Note: these cutters screw directly onto the spindle of the machine therefore rely on the spindle being in a good true state.
