{"product_id":"3d内冷钻头钨钢钻头三倍径高硬质合金高硬度打孔涂层定柄麻花钻","title":"3D Carbide Twist Drill Internal Coolant Coated CNC Drill HRC 55","description":"The 3D Solid Carbide Internal Coolant Drill is designed for high-efficiency and stable drilling in steel, stainless steel, and alloy materials. With a length-to-diameter ratio of 3 times the drill diameter, it provides excellent rigidity and stability during CNC machining operations.\u003cbr\u003e\n\u003cbr\u003e\nThe internal coolant (through coolant) design delivers cutting fluid directly to the cutting edge, significantly improving cooling performance and chip evacuation efficiency. This reduces cutting heat, minimizes tool wear, and enhances drilling stability in deep hole applications.\u003cbr\u003e\n\u003cbr\u003e\nManufactured from premium micro-grain solid carbide, the tool ensures high rigidity, wear resistance, and long service life under high-speed machining conditions. The coated surface further improves heat resistance and cutting performance.\u003cbr\u003e\n\u003cbr\u003e\nThis drill is widely used in precision mechanical components, mold manufacturing, automotive parts, and general CNC machining where stable and efficient drilling is required.\n\u003ch2 class=\"PDq2pG_selectionAnchorContainer\" data-end=\"1866\" data-section-id=\"fb2mdy\" data-start=\"1853\"\u003e✔ Features\u003cspan aria-hidden=\"true\" class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\n\u003c\/h2\u003e\n\n\u003cdiv class=\"relative w-full mt-4 mb-1\"\u003e\n\u003cdiv\u003e\n\u003cdiv class=\"contents\"\u003e\n\u003cdiv class=\"relative\"\u003e\n\u003cdiv class=\"h-full min-h-0 min-w-0\"\u003e\n\u003cdiv class=\"h-full min-h-0 min-w-0\"\u003e\n\u003cdiv class=\"border border-token-border-light border-radius-3xl corner-superellipse\/1.1 rounded-3xl\"\u003e\n\u003cdiv class=\"h-full w-full border-radius-3xl bg-token-bg-elevated-secondary corner-superellipse\/1.1 overflow-clip rounded-3xl lxnfua_clipPathFallback\"\u003e\n\u003cdiv class=\"relative\"\u003e\n\u003cdiv class=\"pe-11 pt-3\"\u003e\n\u003cdiv class=\"relative z-0 flex max-w-full\"\u003e\n\u003cdiv class=\"q9tKkq_viewer cm-editor z-10 light:cm-light dark:cm-light flex h-full w-full flex-col items-stretch ͼd ͼr\" dir=\"ltr\" id=\"code-block-viewer\"\u003e\n\u003cdiv class=\"cm-scroller\"\u003e\n\u003cpre class=\"cm-content q9tKkq_readonly m-0\"\u003e\u003ccode\u003e\u003cspan\u003e• Solid carbide construction for high rigidity and long tool life\u003c\/span\u003e\n\u003cspan\u003e• 3D drilling ratio for stable short deep hole machining\u003c\/span\u003e\n\u003cspan\u003e• Internal coolant system for efficient chip evacuation\u003c\/span\u003e\n\u003cspan\u003e• Coated surface for reduced friction and heat resistance\u003c\/span\u003e\n\u003cspan\u003e• Suitable for steel, stainless steel, and alloy materials\u003c\/span\u003e\n\u003cspan\u003e• High precision CNC drilling performance\u003c\/span\u003e\n\u003cspan\u003e• Reduced chip clogging in deep hole machining\u003c\/span\u003e\u003c\/code\u003e\u003c\/pre\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n","brand":"XUHAN Cutting tools","offers":[{"title":"Ф(3.0-3.7)*20*D4*62L","offer_id":47898563379358,"sku":"Ф(3.0-3.7)*20*D4*62L","price":8.89,"currency_code":"USD","in_stock":true},{"title":"Ф(3.8-4.0)*24*D4*62L","offer_id":47898563412126,"sku":"Ф(3.8-4.0)*24*D4*62L","price":8.89,"currency_code":"USD","in_stock":true},{"title":"Ф(4.1-4.7)*24*D6*66L","offer_id":47898563444894,"sku":"Ф(4.1-4.7)*24*D6*66L","price":15.98,"currency_code":"USD","in_stock":true},{"title":"Ф(4.8-6.0)*28*D6*66L","offer_id":47898563477662,"sku":"Ф(4.8-6.0)*28*D6*66L","price":15.98,"currency_code":"USD","in_stock":true},{"title":"Ф(6.1-7.0)*34*D8*79L","offer_id":47898563510430,"sku":"Ф(6.1-7.0)*34*D8*79L","price":28.87,"currency_code":"USD","in_stock":true},{"title":"Ф(7.1-8.0)*41*D8*79L","offer_id":47898563543198,"sku":"Ф(7.1-8.0)*41*D8*79L","price":28.87,"currency_code":"USD","in_stock":true},{"title":"Ф(8.1-10.0)*47*D10*89L","offer_id":47898563575966,"sku":"Ф(8.1-10.0)*47*D10*89L","price":44.76,"currency_code":"USD","in_stock":true},{"title":"Ф(10.1-12.0)*55*D12*102L","offer_id":47898563608734,"sku":"Ф(10.1-12.0)*55*D12*102L","price":68.34,"currency_code":"USD","in_stock":true},{"title":"Ф(12.1-14.0)*60*D14*107L","offer_id":47898563641502,"sku":"Ф(12.1-14.0)*60*D14*107L","price":92.72,"currency_code":"USD","in_stock":true},{"title":"Ф(14.1-16.0)*65*D16*115L","offer_id":47898563674270,"sku":"Ф(14.1-16.0)*65*D16*115L","price":125.29,"currency_code":"USD","in_stock":true},{"title":"Ф(16.1-18.0)*73*D18*123L","offer_id":47898563707038,"sku":"Ф(16.1-18.0)*73*D18*123L","price":163.66,"currency_code":"USD","in_stock":true},{"title":"Ф(18.1-20.0)*79*D20*131L","offer_id":47898563739806,"sku":"Ф(18.1-20.0)*79*D20*131L","price":211.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0562\/2264\/6430\/files\/1582864d1c4c72618112d9b71d855f2c.jpg?v=1782284841","url":"https:\/\/www.cnctool.store\/products\/3d%e5%86%85%e5%86%b7%e9%92%bb%e5%a4%b4%e9%92%a8%e9%92%a2%e9%92%bb%e5%a4%b4%e4%b8%89%e5%80%8d%e5%be%84%e9%ab%98%e7%a1%ac%e8%b4%a8%e5%90%88%e9%87%91%e9%ab%98%e7%a1%ac%e5%ba%a6%e6%89%93%e5%ad%94%e6%b6%82%e5%b1%82%e5%ae%9a%e6%9f%84%e9%ba%bb%e8%8a%b1%e9%92%bb","provider":"XUHAN Cutting tools","version":"1.0","type":"link"}
