The object in this study is to establish "Mild Cooling Air Machining Method" that has a cooling effect equal to conventional cooling air machining. The basic way of thinking for it is that removing cutting heat by two ways : One of them is removed by about -5℃ mild cooling air. The other is removed by tool side which is applied removing cutting heat contrivance. In this paper, one of removing heat ways : from tool is noticed. And relationships between removed heat and tip temperature, tip wear, machined surface roughness are considered. After that, thermal conductivity analysis about removing heat effect from tool side is also tested, and compared with an observation result. As collect, following results are obtained, 1) When cutting heat is removed from tool side, tip temperature drops, and tip flank wear width and ten point average roughness are reduced. And tip wear and machined surface roughness are improved by increasing the removed heat. 2) It is indicated that predicting whole tendency is possible by using thermal conductivity analysis
