Abstract
A cutting tool having a body that is cylindrical in shape having a shank at one end and a cutting end opposite thereof. The cutting end has an even number of flutes thereon with every other flute being a cutting flute, such as a knuckle flute including a radial knuckle flute and a flat crested knuckle flute, or a diamond cut flute that cuts material. Every other flute therebetween the cutting flutes are wiper flutes that wipe or clean the cut material. The wiper flutes have a larger diameter than the cutting flutes thereby enabling the wiper flutes to remove any unnecessary debris and finish the material in a single step.
