UD4122M ('M' = mortise style):

  • the tool is designed with shorter up-cut end flutes
  • applying a down shear action to the top surface during shallow cuts
  • great for dado cutting
  • shorter up cut is preferred on slot or mortise cutting; whilst the important upward feed of chip is still maintained, the top surface being cut is engaged by the downward shear from the down cut spiral
