Abstract
This disclosure relates to a cutting tool, having a main body, a cutting head, which is joined to the free end of the main body and is formed, by primary shaping, as a sintered piece provided with at least one cutting edge, and a cooling lubricant feed, which is led through the main body axially and which has a cooling lubricant distributor inserted into the cutting head for redirecting cooling lubricant into the region of the at least one cutting edge. According to this disclosure, a plurality of protruding spacers for keeping a gap clear with respect to the cooling lubricant distributor and/or the main body are sintered on a supporting surface of the cutting head as primary shaped elements.
Claims16
A cutting tool, comprising:
- a main body having a longitudinal central axis and configured to be clamped in a tool holder;
- a sintered cutting head joined to a free end of the main body, the cutting head having at least one cutting edge and a cooling lubricant feed which is led through the main body axially;
- a cooling lubricant distributor inserted into the cutting head and configured for redirecting cooling lubricant into a region of the at least one cutting edge;
- and
- a plurality of primary shaped protruding spacers sintered on a supporting surface of the cutting head, the spacers configured to maintain a gap for flow of the cooling lubricant.
A cutting tool, comprising:
- a main body having a longitudinal central axis and configured to be clamped in a tool holder;
- a sintered cutting head integrally bonded to a free end of the main body, the cutting head having at least one cutting edge and a cooling lubricant supply which is led through the main body axially;
- a cooling lubricant distributor inserted into the cutting head and configured for redirecting cooling lubricant into a region of the at least one cutting edge;
- and
- at least one depression formed in a supporting surface of the cutting head, the at least one depression delimiting a passage for cooling lubricant relative to the cooling lubricant distributor.
