Abstract
One-piece reamer cutting discs including integral engagement and cutting portions are disclosed. The engagement portion may allow for torque transmission and alignment of the reamer cutting disc on a reamer tool body. The integral engagement portion and cutting portion allows for the cutting portion to be provided closer to the end of the tool body. The one-piece reamer cutting discs may be mounted on a tool body having coolant outlets that direct coolant from the tool body to the exterior surface of the cutting disc.
Claims20
A reamer cutting disc and tool body assembly comprising:
- a tool body comprising an axial forward end having a generally planar front face intersecting with an outer tool surface of the tool body to form a continuous outer diameter, a first socket portion having a continuous inner surface extending from the generally planar front face and a second socket portion adjacent to the first socket portion;
- and
- a reamer cutting disc engageable with the tool body comprising:
- a cutting portion comprising a generally planar front face, a generally planar rear face and a longitudinally-extending outer edge;
- and
- an engagement shank extending from the generally planar rear face of the cutting portion comprising a torque transmission portion adjacent to the generally planar rear face and an alignment portion adjacent to the torque transmission portion,
- wherein the reamer cutting disc does not include internal coolant channel.
