Claim:
1. A milling tool comprising: a body, said body being rotatable about a first axis; at least one cutting tooth mounted on the body having a cutting edge for cutting about said first axis; and a wiper tooth comprising a round wiper cutting insert, said insert being round about a second axis and having a peripheral surface about said second axis; wherein said peripheral surface intersects a face surface defining a cutting edge that is round about said second axis for cutting about said first axis, wherein said wiper cutting insert cutting edge is formed along a first plane offset at a first angle relative to a second plane perpendicular to said first axis and below said first plane, wherein said first angle is formed along a third plane perpendicular to said first and second planes, wherein a body radius extends perpendicularly from said first axis, said body radius being tangent to said wiper cutting insert cutting edge, wherein said third plane is axially along a diameter of the wiper tooth cutting insert, wherein said third plane extends at a third plane angle relative to the body radius, said third plane angle being in a range of angles as measured from a wiper tooth radius extending perpendicular from said body radius in a direction of cutting to an angle less than 90° as measured from said wiper tooth radius in a direction outward toward the body radius, wherein the third plane intersects said cutting edge at a point, wherein said point is furthest axially from the second plane than any other point on said cutting edge.
