PROBLEM TO BE SOLVED: To suppress the occurrence of tipping even if making use without reducing a working speed in a condition for maintaining abrasion resistance by coating a coat having a base composition of an AIOx (1.0≤x≤1.5) on a high-speed tool steel. ;SOLUTION: Many throwaway tips 2 are fitted to the outer periphery of a tool main body 1 supported on the tool main spindle of a milling machine, etc., and the respective tips 2 are fixed respectively by a wedge 3 and a clamp screw 4 for clamping. A throwaway tip 2 made of a high-speed tool steel (a high-speed steel), coated by the oxide of Al, is used as the tip 2. When a coated coat of material having a basic composition of AIOx in a range of 1.0≤x≤1.5 can be obtained, flank abrasion can be limited practical friction limit or less at a cutting speed of 550 m/min, or less, and practicability is thereby obtained.;COPYRIGHT: (C)1999,JPO
