Abstract
A metal cutting tool includes a tool body rotatable about a center axis and a tool tip mounted on a front surface of said tool body for performing a cutting operation. A draw bar mounted axially in the tool body draws a rear surface of the tool tip toward the front surface of the tool body. Those front and rear surfaces include radial projections and radial recesses receiving the projections. The projections are wedgingly connected in the recesses to transmit all axial and rotational forces between the tool body and tool tip.
Claims21
A tool for rotary chip removing of a workpiece, comprising:
- a tool body having a shank and a front surface, said shank defining an axis of rotation;
- a tool tip formed of cemented carbide and having front and rear surfaces, said front surface including at least one cutting edge;
- said rear surface facing said front surface of said tool body and including a rearwardly open central blind hole;
- and
- a retention member disposed in said tool body and engaged in said blind hole;
- said rear surface of said tool tip and said front surface of said tool body including interengaging projections and recesses for transferring all axial and rotary forces between said cutting tip and said cutting body, each recess extending along a first line forming an acute angle with a second line along which an adjacent recess extends.
A rotary tool tip for chip removing machinery, said tip formed of cemented carbide and generally having a circular shape with front and rear surfaces defining a center axis, said front surface including at least one edge of one piece integral construction, therewith, and extending from an outer periphery of said tool tip to a location adjacent said axis, said rear surface having rearwardly protruding projections adapted to be received in recesses of a tool body, said projections extending along respective lines forming acute angles with one another, said rear surface including a rearwardly open blind hole adapted to receive a retention member for securing said tool tip to a tool body.
A rotary tool body in combination with a retention member, said tool body comprising a shank defining an axis of rotation, a front surface adapted to receive a cutting tip, and an outer peripheral surface including chip flutes;
- said front surfaces including recesses arranged on respective lines forming acute angles with one another;
- said tool body including a control channel extending therethrough receiving said retention member, said retention member adapted to be secured to a tool tip.
