摘要： PROBLEM TO BE SOLVED: To provide a cutting tool capable of more increasing an agglutination preventing effect with excellent wear resistance, when cutting a metal material of high hardness.
SOLUTION: This cutting tool is provided with a cutting base material 2 and a cutting edge tip 3 made of a cemented carbide material having higher wear than that of the cutting base material 2 and fixed to the cutting base material 2. In vicinities 31 and 32 of a portion in contact with at least a material to be cut of the cutting edge tip 3, hard protective films 4 including at least any one kind of Al-O system, Al-Ti-O system and Al-Zr-O system composite oxide, and carbide system and nitride system silicon compound are coated.

摘要： PROBLEM TO BE SOLVED: To provide a method for suppressing surface indentation flaw in an element tube (an element tube for a seamless steel tube) applied with correction by a straightener after made by hot tube making, and thereafter provided for cold working.SOLUTION: In time of the correction by the straightener, cooling water is sprayed onto the whole faces of rolls constituting the straightener, and a load applied to the straightener rolls is set to be 550 kN or below to perform light rolling reduction of the tube stock. It is effective that a hot straightener applying the correction such as bend removal to the tube stock present in a temperature range of 500-550°C after the hot tube making is used as a means of the light rolling reduction. It is preferable to perform the spray of the cooling water onto the whole roll faces by at least one means of means of angle widening of a tip shape of each cooling nozzle, proper arrangement of the cooling nozzles 5, and increase of a spray water amount of the cooling water.
