摘要:
A cutting tool includes a substrate composed of a cermet. The cermet includes a hard phase including compounds containing Ti, at least one metal other than Ti selected from groups 4, 5, and 6 of the periodic table, and at least one element of carbon and nitrogen, a binder phase including, as a main component, an iron group metal, and unavoidable impurities. At least one type of particles selected from alumina particles and zirconia particles with an average particle size of 0.5 µm or more and 5 µm or less is scattered over a surface of a rake face of the substrate, and the concentration of at least one element of aluminum and zirconium in the surface is 0.5 at% or more and 5 at% or less.

The present invention provides a cutting edge-replaceable cutting tool (10) including a tool body (12), and a cutting insert (14) is removably installed on the tool body (12). The cutting tool-replaceable cutting tool (10) includes an insert mounting seat (16) formed on the tool body (12) and on which the cutting insert (14) is mounted, and a upper wall portion (18) formed integrally with the tool body (12) and overhanging the insert mounting seat (16).

摘要:
A tool (10) for removing material from a workpiece (12) includes a tool body (16) equipped with at least one roughing head (18) and at least one finishing head (20). The finishing head (20) includes a holder (68) containing at least first and second finishing inserts (86, 88). The first finishing insert (86) has a cutting edge (101) which extends a distance F1 from the tool body (16). The second finishing insert (88) has a cutting edge (101) which extends a distance F2 from the tool body (16). The distance F1 is less than the distance F2.
