Abstract: The present invention relates to a spot and chamfer drill insert which can be utilized to create accurately located spots for subsequent drilling operations while simultaneously providing a chamfer for the finished hole. The present invention utilizes web thin clearance surfaces that are formed at web thin clearance angles, wherein the web thin clearance angles are oriented with respect to a projected plane normal to a plane through the web thin cutting edge and parallel to the longitudinal axis of the insert, wherein the projected plane is tangent to the web thin cutting edge.

Abstract: The present invention provides a new cutting tool assembly comprising a replaceable cutting head and a tool body having a common longitudinal axis and mating peripheral surfaces. The cutting head has a cutting portion forming a leading end, a pilot portion forming a trailing end, and a cutting head mounting portion adjacent the trailing end of the cutting head. The tool body has a cutting head receiving portion formed at a leading end of the tool body and a pilot recess disposed in the leading end of the tool body to matingly receive the pilot portion of the cutting head. The cutting head mounting portion and the cutting head receiving portion of the tool body each have at least two coupling portions. The cutting head coupling portions and the tool body coupling portions are bound by their peripheral surfaces and generally mate in shape and dimensions. Each coupling portion has a pair of base surfaces, including upper and lower surfaces. The base surfaces extend transversely to the longitudinal axis and provide support of the cutting head in the tool body. A torque transmission wall extends between the upper and lower base surfaces from the pilot portion surface in a generally transverse direction relative to the longitudinal axis and oriented transversely to the base surfaces. A fastener may be disposed in the tool body along its longitudinal axis where it matingly engages the pilot portion of the cutting head and exerts an axial force on the cutting head for pressing the cutting head mounting portion against the cutting head receiving portion of the tool body.

Abstract: The present invention provides a novel drill insert having chipbreakers, or chip splitting grooves formed through the cutting surfaces. The cutting tool insert has a specialized geometry including a chip splitting groove formed at a negative rake angle. The chip splitting grooves increase the cutting efficiency of the tool while allowing the edge strength to be increased while also allowing higher feed rates.
