  • Cutting instrument and methods for implementing same
    Patent number: 8657537
    Abstract: A rotating cutting tool (10, 110) includes a body (12, 112) with a longitudinal axis (14, 114) and at least one flute (16, 116) and one active part (18, 118). Each active part has a peripheral surface including: a radial cutting edge (20, 120) that is at a cutting distance (Rc) from the longitudinal axis, a clearance face (30, 130) that is at a final clearance distance (Rd) from the longitudinal axis, and a control face (40, 140) that is at a penetration control distance (Rp) from the longitudinal axis. These distances satisfy the relation: 0<?p<?d, with ?p=|Rc?Rp| and ?d=|Rc?Rd|.
