Based on the CoroDrill 870 platform, this insert-style drill accepts a replaceable carbide tip seated in a size 17 insert seat, allowing the body to be reused across multiple tip changes. The tip carries an AlTiCrN PVD coating applied to a fine grain carbide substrate in manufacturer grade 2334, providing heat resistance and edge retention when drilling stainless steel, superalloys, and titanium. The drill point features a 142-degree included angle with a standard point type and regular helical flute geometry across two flutes.\u003c\/p\u003e\n\u003cp\u003eThis drill is intended for solid drilling operations in ferrous and high-temperature alloy applications, classified under ISO material groups M and S. Typical use is in CNC machining centers where the CoroDrill 870 shank body is already in use and only the replaceable tip requires replacement. The 17.46mm cutting diameter makes it well suited for close-tolerance bores in aerospace components, fluid system bodies, and structural parts machined from stainless or titanium alloys. The clamp-style insert holding method secures the tip mechanically without adhesive.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide tip with AlTiCrN PVD coating for heat and wear resistance in M and S material groups\u003c\/li\u003e\n  \u003cli\u003eFine grain carbide substrate in manufacturer grade 2334 for toughness in interrupted and continuous cuts\u003c\/li\u003e\n  \u003cli\u003e142-degree drill point angle optimized for stainless steel and superalloy entry geometry\u003c\/li\u003e\n  \u003cli\u003eReplaceable tip design compatible with CoroDrill 870 series bodies, reducing tooling cost per hole\u003c\/li\u003e\n  \u003cli\u003eTwo helical flutes with regular spiral for chip evacuation in deep-hole solid drilling\u003c\/li\u003e\n  \u003cli\u003eClamp-style mechanical holding for repeatable tip indexing without adhesive or press-fit\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 bodies accepting insert seat size 17.

The machine spindle must be fully stopped and the tool change confirmed safe before seating or removing the carbide tip. Use the manufacturer-specified torx or clamp key for the CoroDrill 870 holding mechanism — do not overtighten by hand or substitute fasteners. Inspect the insert seat for chips or debris before seating a new tip, as contamination affects runout and tip retention.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 17.46mm (0.6874 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 17\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 2334\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Fine Grain\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiCrN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 142 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Geometry\u003c\/strong\u003e: MM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 8.00mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFunctional Length\u003c\/strong\u003e: 0.3126 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length \/ Projection\u003c\/strong\u003e: 0.4173 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 11.00mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Superalloys, Titanium (ISO M, S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Solid Drilling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroDrill 870\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Number\u003c\/strong\u003e: 870-1746-17-MM 2334\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 10.24 inches (L) x 11.81 inches (W) x 5.51 inches (H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.024 pounds\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: 7357869\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51731240911154,"sku":"7357869","price":218.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f5aab03d00ff712ae1c2a8848bd42ff6_1a8d760f-5822-4991-81c8-c474f8f29dbe.jpg?v=1788728727","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7357869-carbide-replaceable-tip-drill","provider":"Voomi Supply","version":"1.0","type":"link"}
