Pure　iron　has　recently　been　identified　as　the　material　basis　of　many　high-tech　industries　due　to　its　high　toughness,　plasticity　as　well　as　superior　electromagnetism.　However,　the　rather　poor　machinability　has　limited　the　wider　applications　of　pure　iron.　Nano-laminated　multilayer　graphene-carbide　tool　(MLG/WC-Co)　was　produced　employing　two-step　sintering.　This　study　applied　towards　investigate　the　microstructure　and　mechanical　properties　of　this　MLG/WC-Co　tool,　highlighting　its　machining　performance　through　dry　turning　pure　iron.　Results　showed　that　compared　with　commercially　available　YG6　tool,　MLG/WC-Co　tool　yielded　reduced　cutting　forces,　cutting　temperature　and　friction　coefficient　at　the　tool-chip　interface　together　with　enhanced　shear　angle　and　tool　life.　The　MLG/WC-Co　tool　developed　cooperative　adaptive　mechanism　for　the　coupled　and　interacted　thermal-mechanical-chemical　multi-fields　were　determined　thoroughly.　For　one　thing,　the　wear　resistance　was　significantly　enhanced　as　a　function　of　the　MLG　introduced　strengthening　and　toughening　mechanisms.　For　another,　cutting　force　induced　tensile　stress　could　be　compensated　by　the　residual　compressive　stress　on　the　rake　face　resulting　from　the　laminated　structure.　Furthermore,　extensive　MLG　film　formed　at　tool-chip　interface　at　high-speed　cutting　conditions,　endowing　the　cutting　tool　self-lubricating　function　coupled　with　exceptional　adhesive-wear　and　oxidation　resistance.　Besides,　the　orientation　conduction　of　cutting　heat　was　proposed　by　associated　consideration　of　tool　structure　as　well　as　orientation　distribution　and　anisotropic　heat　conductivity　of　MLG,　so　as　to　effectively　slow　down　the　heat　accumulation　and　temperature　rise.　This　research　can　ease　the　overwhelming　pressure　associated　with　sustainability　by　eradicating　or　circumventing　the　undesirable　effects　of　traditional　cutting　fluids　for　economy,　healthy　coupled　with　environment　through　advancing　dry　machining　techniques.　©　2021　Elsevier　Ltd
