{"product_id":"5d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":"5D Carbide Twist Drill Internal Coolant Coated CNC Drill HRC 55","description":"The 5D Solid Carbide Internal Coolant Drill is designed for high-efficiency deep hole drilling applications in steel, stainless steel, and alloy materials. With a length-to-diameter ratio of 5 times the drill diameter, this tool is optimized for stable deep hole machining with excellent chip evacuation.\u003cbr\u003e\n\u003cbr\u003e\nThe internal coolant (through coolant) design delivers cutting fluid directly to the cutting edge, significantly improving cooling efficiency, reducing cutting heat, and enhancing chip removal performance. This allows for deeper drilling with higher stability and reduced tool wear.\u003cbr\u003e\n\u003cbr\u003e\nManufactured from premium micro-grain solid carbide, the drill offers superior rigidity, wear resistance, and long tool life under high-speed CNC machining conditions. The coated surface further enhances heat resistance and reduces friction during cutting operations.\u003cbr\u003e\n\u003cbr\u003e\nThis tool is widely used in automotive components, mold manufacturing, aerospace parts, and general mechanical engineering where deep hole precision drilling is required.\n\u003ch2 class=\"PDq2pG_selectionAnchorContainer\" data-end=\"1932\" data-section-id=\"fb2mdy\" data-start=\"1919\"\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 durability\u003c\/span\u003e\n\u003cspan\u003e• 5D deep hole drilling capability for extended reach\u003c\/span\u003e\n\u003cspan\u003e• Internal coolant design for efficient chip evacuation\u003c\/span\u003e\n\u003cspan\u003e• Coated surface for improved wear resistance and tool life\u003c\/span\u003e\n\u003cspan\u003e• Suitable for steel, stainless steel, and alloy materials\u003c\/span\u003e\n\u003cspan\u003e• Stable performance in high-speed CNC machining\u003c\/span\u003e\n\u003cspan\u003e• Reduced heat buildup during deep hole drilling\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)*28*D4*66L","offer_id":47898550206622,"sku":"Ф(3.0-3.7)*28*D4*66L","price":10.46,"currency_code":"USD","in_stock":true},{"title":"Ф(3.8-4.0)*36*D4*66L","offer_id":47898550239390,"sku":"Ф(3.8-4.0)*36*D4*66L","price":10.46,"currency_code":"USD","in_stock":true},{"title":"Ф(4.1-4.7)*36*D6*74L","offer_id":47898550272158,"sku":"Ф(4.1-4.7)*36*D6*74L","price":19.07,"currency_code":"USD","in_stock":true},{"title":"Ф(4.8-6.0)*44*D6*82L","offer_id":47898550304926,"sku":"Ф(4.8-6.0)*44*D6*82L","price":20.99,"currency_code":"USD","in_stock":true},{"title":"Ф(6.1-8.0)*53*D8*91L","offer_id":47898550337694,"sku":"Ф(6.1-8.0)*53*D8*91L","price":35.53,"currency_code":"USD","in_stock":true},{"title":"Ф(8.1-10.0)*61*D10*103L","offer_id":47898550370462,"sku":"Ф(8.1-10.0)*61*D10*103L","price":56.66,"currency_code":"USD","in_stock":true},{"title":"Ф(10.1-12.0)*71*D12*118L","offer_id":47898550403230,"sku":"Ф(10.1-12.0)*71*D12*118L","price":86.39,"currency_code":"USD","in_stock":true},{"title":"Ф(12.1-14.0)*77*D14*124L","offer_id":47898550435998,"sku":"Ф(12.1-14.0)*77*D14*124L","price":119.9,"currency_code":"USD","in_stock":true},{"title":"Ф(14.1-16.0)*83*D16*133L","offer_id":47898550468766,"sku":"Ф(14.1-16.0)*83*D16*133L","price":161.23,"currency_code":"USD","in_stock":true},{"title":"Ф(16.1-18.0)*93*D18*143L","offer_id":47898550501534,"sku":"Ф(16.1-18.0)*93*D18*143L","price":209.25,"currency_code":"USD","in_stock":true},{"title":"Ф(18.1-20.0)*101*D20*153L","offer_id":47898550534302,"sku":"Ф(18.1-20.0)*101*D20*153L","price":276.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0562\/2264\/6430\/files\/1256da59383ab6a9236002ec6bc8f8e6.jpg?v=1782284557","url":"https:\/\/www.cnctool.store\/products\/5d%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"}
