    Abstract: PROBLEM TO BE SOLVED: To provide a cutting tool insert, a solid end mill or a drill including a substrate and a coating film. SOLUTION: The coating film is constituted of one or a plurality of layers of a refractory compound. At least one of layers of the refractory compound contains a cubic crystal (Me, Si)X phase where Me refers to one or more of Ti, V, Cr, Zr, Nb, Mo, Hf, Ta and Al, and X refers to one or more of elements N, C, O and B. A ratio R (X ratio/Me ratio) of a c-MeSiX phase is 0.5-1.0, and X contains O+B by a quantity less than 30 atom%. The invention is especially useful in application for machining metal with producing small chips and for a hard material to be machined, for example in copy-milling through the use of the solid end mill, milling an insert or boring hardened steel.

    Abstract: PROBLEM TO BE SOLVED: To prevent a plastic deformation of a fastener for a tool by providing a stopper for the fastener. SOLUTION: A tool 10 has a holder 11 having a cutting insert recess 12. The holder 11 has an inclined surface provided at a distance from the cutting insert recess 12. The inclined surface is inclined in the direction downward from the cutting insert recess 12. The holder 11 has a screw hole for fastening a faster. A cutting insert 21 is provided on the cutting insert recess 12, having an upper surface 22 at least a part of which is flat. A fastening means 25 for operating in cooperation with a fastener hole 37 and a hole is provided so as to push the cutting insert 21 toward inside in the above direction in attaching the cutting insert 21. The fastener and the holder 11 have a spring and/or a stopper surface provided against the fasteners movement direction.

    Abstract: PROBLEM TO BE SOLVED: To safely operate a milling cutter tool provided with an inserted cutting blade possessing a plurality of cutting blades and to prevent transmission of an occurable crack to a holder main body by using an inserted blade provided with an integrated shim with a defined acute corner. SOLUTION: A holder is provided with a fastening tool 33 and an inserted cutting blade 10 provided with a pocket including at least a shoulder in the radial direction. The inserted cutting blade 10 is formed into an octagonal base shape and provided with eight cutting blades 16 (16D, 16E, 16F, ...) formed by a transient part between the upper side face of the inserted blade and the blade face. The upper side face is provided with a plurality of projection parts. The projection parts facing each other separately from cooperating cutting blades are leant onto the fastening tool 33 when the inserted blade 10 is moved in the radial direction.

    Abstract: PURPOSE: To form a split surface at the time of cutting into a flat surface with good finishing by forming the highest level area on the identical side to an insert as a cutting edge advances cutting, at a first surface and/or a rake surface. CONSTITUTION: This cutting insert 10 splits a rod or the like while rotating, whereas an angle λ is formed between a line 16 coming into contact with a first surface 15 and parallel to a cutting edge 12 and a line perpendicular to the tangential direction T at a processing position, and an angle γ is formed between a line 19 coming into contact with a rake surface 18 and parallel to the cutting edge 12 and a line 20 perpendicular to the tangential direction T to provide the highest level area on the identical side to the insert 10 at both surfaces 15, 18 as the cutting edge 12 advances cutting. A cutting edge front edge angle is set at 4 to 8 degrees, λ is at 1 to 4 degrees, and γ is at 4 to 7 degrees. It is thus possible to obtain a flat surface whose split surface is a good finishing surface in using the cutting insert for cutting work.
