high-chromium cold-work tool steel used for blanking dies, forming tools,\n        shear blades, and other wear-resistant tooling. The same chromium carbides that give D2 its\n        excellent wear resistance and dimensional stability also make it one of the harder cold-work\n        steels to machine.\n      <\/p>\n      <p>\n        Equivalent grades include DIN 1.2379 and JIS SKD11. The practical machining guidance below\n        applies to D2, 1.2379, SKD11, and closely related D2-type cold work tool steels.\n      <\/p>\n    <\/header>\n\n    <article class=\"aobo-article\">\n      <p>\n        D2 should normally be rough-machined in the annealed condition before heat treatment. In this\n        condition it can be turned, milled, drilled, and ground with suitable carbide, cermet, or\n        high-quality tool materials, but cutting speeds must stay conservative because its chromium-rich\n        carbides cause rapid tool wear.\n      <\/p>\n      <p>\n        After hardening to about 58-60 HRC, conventional turning, milling, and drilling become much\n        more difficult. The work is usually finished by grinding, EDM, PCBN hard turning, or controlled\n        hard milling. The correct parameters depend on steel condition, tool material, machine rigidity,\n        coolant control, and required surface finish.\n      <\/p>\n\n      <h2>Resumo r\u00e1pido dos par\u00e2metros do a\u00e7o ferramenta D2<\/h2>\n      <div class=\"aobo-table-wrap\">\n        <table class=\"aobo-table\">\n          <thead>\n            <tr>\n              <th>Opera\u00e7\u00e3o<\/th>\n              <th>Condi\u00e7\u00f5es do material<\/th>\n              <th>Ferramenta ou processo recomendado<\/th>\n              <th>Nota pr\u00e1tica<\/th>\n            <\/tr>\n          <\/thead>\n          <tbody>\n            <tr><td>Curvatura brusca<\/td><td>Recozido, cerca de 200-250 HB<\/td><td>Carboneto revestido<\/td><td>Use uma velocidade conservadora, pois o D2 \u00e9 abrasivo.<\/td><\/tr>\n            <tr><td>Termine de virar<\/td><td>Recozido<\/td><td>Carboneto revestido ou cermet<\/td><td>O Cermet pode atingir velocidades maiores, mas apenas com uma configura\u00e7\u00e3o est\u00e1vel.<\/td><\/tr>\n            <tr><td>Curva acentuada<\/td><td>Endurecido, aproximadamente 58-60 HRC<\/td><td>PCBN ou cer\u00e2mica<\/td><td>Principalmente para acabamento, n\u00e3o para remo\u00e7\u00e3o pesada de material.<\/td><\/tr>\n            <tr><td>Fresagem<\/td><td>Recozido preferencialmente<\/td><td>Carboneto revestido ou a\u00e7o r\u00e1pido de alta qualidade<\/td><td>Mantenha a sali\u00eancia da ferramenta curta e evite vibra\u00e7\u00f5es.<\/td><\/tr>\n            <tr><td>Moagem dura<\/td><td>Endurecido, aproximadamente 58-60 HRC<\/td><td>Carboneto revestido ou PCBN<\/td><td>Requer m\u00e1quinas r\u00edgidas e engate est\u00e1vel.<\/td><\/tr>\n            <tr><td>Perfura\u00e7\u00e3o<\/td><td>Recozido preferencialmente<\/td><td>Brocas de a\u00e7o r\u00e1pido com cobalto, com ponta de metal duro ou de metal duro maci\u00e7o.<\/td><td>Perfure antes da t\u00eampera, sempre que poss\u00edvel.<\/td><\/tr>\n            <tr><td>Moagem<\/td><td>Recozido ou endurecido<\/td><td>Rodas convencionais, SG ou CBN<\/td><td>Controle o calor para evitar queimaduras e rachaduras.<\/td><\/tr>\n          <\/tbody>\n        <\/table>\n      <\/div>\n\n      <h2>Por que o a\u00e7o ferramenta D2 \u00e9 dif\u00edcil de usinar?<\/h2>\n      <p>\n        D2 is widely recognized as difficult to machine compared with conventional steels. Its high\n        carbon and chromium content forms hard chromium-rich carbides distributed through the steel\n        matrix. During cutting, these carbides behave like abrasive inclusions, accelerating tool wear\n        and increasing cutting forces.\n      <\/p>\n      <p>\n        A practical machinability rating for D2 is around 45 percent, compared with 100 percent for a\n        1 percent carbon water-hardening tool steel such as W1. In practice this means lower cutting\n        speeds, stronger cutting tools, rigid workholding, and careful heat control.\n      <\/p>\n      <p>\n        The steel condition has the biggest effect on parameter selection. Annealed D2 is much easier\n        to machine because its spheroidized carbides sit in a softer matrix. Hardened D2, normally\n        about 58-60 HRC in cold-work tooling, requires PCBN, ceramic tools, grinding, or EDM for\n        final finishing. For this reason, most stock removal should be completed before heat treatment,\n        and post-hardening machining should be limited to final dimensional correction and surface\n        finishing. The full hardening cycle is covered in our\n        <a href=\"https:\/\/aobosteel.com\/pt\/d2-tool-steel-heat-treatment-guide\/\">Guia de tratamento t\u00e9rmico de a\u00e7o para ferramentas D2<\/a>.\n      <\/p>\n\n      <h2>Par\u00e2metros de torneamento para a\u00e7o ferramenta D2 recozido<\/h2>\n      <p>\n        D2 is normally turned in the annealed condition before hardening.
