The tip measures 11.11mm (0.4374 inch) in cutting diameter and features a 142-degree drill point angle with a TiAlN coating applied via PVD process. It carries manufacturer grade 4334 with a fine grain carbide substrate, delivering consistent hole quality and tool life across a broad range of workpiece materials. Licensed machinists and CNC operators install this insert as a precision-fit replacement in compatible CoroDrill 870 holders.\u003c\/p\u003e\n\u003cp\u003eThis replaceable tip is suited for solid drilling applications in both horizontal and vertical machining centers, as well as turning centers with driven tooling. Primary workpiece material compatibility spans steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium, corresponding to ISO material codes P, M, K, N, and S. The PM insert geometry and regular helical flute design support stable chip evacuation in through-hole and blind-hole operations at production feed rates.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e11.11mm (0.4374 inch) cutting diameter with 7\/16 inch fractional equivalent\u003c\/li\u003e\n  \u003cli\u003e142-degree drill point angle for standard point geometry entry\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating via PVD process for elevated heat resistance and extended wear life\u003c\/li\u003e\n  \u003cli\u003eFine grain solid carbide substrate, manufacturer grade 4334\u003c\/li\u003e\n  \u003cli\u003e2-flute helical design with PM geometry for consistent chip control\u003c\/li\u003e\n  \u003cli\u003eClamp-style insert holding in insert seat size 8 CoroDrill 870 holders\u003c\/li\u003e\n  \u003cli\u003eCompatible with ISO material groups P, M, K, N, and S workpieces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with CoroDrill 870 series replaceable tip drill holders accepting insert seat size 8.

The machine spindle must be fully stopped and the tool holder secured before tip removal or installation. Use the manufacturer-specified clamping key or torque tool for the insert clamp; do not overtighten by hand. Inspect the insert seat for chips or contamination before seating the new tip to ensure proper contact and runout accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 11.11mm (0.4374 inch \/ 7\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 142 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Fine Grain\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 4334\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroDrill 870\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Geometry\u003c\/strong\u003e: PM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFunctional Length\u003c\/strong\u003e: 0.2047 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\/Projection\u003c\/strong\u003e: 0.2716 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 5.00mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 7.00mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Material Codes\u003c\/strong\u003e: P, M, K, N, S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Solid Drilling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Number\u003c\/strong\u003e: 870-1111-8-PM 4334\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.028 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: 7357599\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51731064914226,"sku":"7357599","price":332.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a1c60e42b88dae248ccf037a21b2e074_dec34df1-9d5d-4045-bbcc-bd390b10c735.jpg?v=1788726496","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7357599-corodrill-870-replaceable-tip-drill","provider":"Voomi Supply","version":"1.0","type":"link"}
