Abstract:
1. A machine tool comprising: a shank having a first end and a second end, the first end configured for engagement with a machine operable to rotate the shank about a longitudinal axis of the machine tool, and the second end being distal from the first end; a cutting portion proximate the second end of the shank, the cutting portion having a first diameter defined by features used to remove material from a workpiece; and a vibration reduction dampener formed from a compressible material and securely positioned on the shank at a location between the first end and the cutting portion and having a second diameter, greater than the first diameter, such that, upon machining engagement of the cutting portion to the workpiece, portions of the vibration reduction dampener are compressed against the workpiece and an axially-extending surface of the shank at a location between the workpiece and the axially-extending surface of the shank to dampen vibrations.
