It measures 0.1110 inches in diameter with a 140-degree drill point angle and features a TiAlN Lite coating for extended tool life in abrasive and heat-intensive applications. The straight-cylindrical shank diameter of 0.1181 inches fits standard collet and drill chuck setups. With through-tool coolant capability and a spiral flute design, this bit is built for controlled chip evacuation in tight, deep-hole work. Machinists and tool-room operators working in CNC machining centers and precision drilling operations are the primary users.\u003c\/p\u003e\n\u003cp\u003eThe CoroDrill 862 series is suited for drilling steel and stainless steel in high-volume production and precision job-shop environments. The 9xD flute-to-diameter ratio supports a maximum drilling depth of 0.9921 inches, making it appropriate for deep micro-hole applications where chip packing and heat buildup are concerns. Right-hand cutting direction is standard for conventional spindle rotation. This bit is a fit for applications requiring tight diameter tolerances and consistent hole quality in P and M material groups per ISO classification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.1110 inch drill diameter with 140-degree split point for accurate entry and reduced thrust\u003c\/li\u003e\n  \u003cli\u003eTiAlN Lite coating improves wear resistance and heat tolerance in steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003eThrough-tool coolant compatible for effective heat management and chip evacuation in deep holes\u003c\/li\u003e\n  \u003cli\u003eSpiral flute design with 9xD ratio supports maximum drilling depth of 0.9921 inches\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank at 0.1181 inches diameter for standard collet compatibility\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction for standard CNC and manual spindle operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with steel (ISO material group P) and stainless steel (ISO material group M) workpieces.

Ensure the spindle and workpiece are fully secured before engaging the drill. Verify coolant line pressure and flow rate are appropriate for through-tool coolant operation before running the cycle. Inspect the cutting edge under magnification before each use, as micro drill bits at this diameter are sensitive to edge chipping and runout.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1110 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.4016 inches (60.96 mm equivalent per decimal; supplier-stated 2.40 mm OAL refers to flute region — see flute length below)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.10 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.9921 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1181 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 9xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN Lite\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (ISO Code P)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Stainless Steel (ISO Code M)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroDrill 862\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SANDVIK COROMANT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 8173244\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51750366249266,"sku":"8173244","price":244.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cb2d73140549b5e77256736a1d722016_fbadbc51-abb6-4268-839a-0c099f03576c.jpg?v=1788915086","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-8173244-micro-drill-bit-0-111in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
