It features a 15.00 mm (0.6102 inches) cutting diameter and a 142-degree drill point angle, making it well suited for stable entry and clean hole formation. The tip is manufactured from solid carbide with a fine grain microstructure and carries an AlTiCrN coating applied via PVD process. This combination delivers strong wear resistance and thermal stability under demanding cutting conditions. Licensed HVAC, plumbing, and mechanical contractors as well as machining professionals install these tips in production and maintenance drilling operations on stainless steel, superalloys, and titanium workpieces.\u003c\/p\u003e\u003cp\u003eThis replaceable drill tip is designed for solid drilling applications in industrial and manufacturing environments. Its helical flute geometry and regular spiral type promote chip evacuation during through-hole and blind-hole operations. The clamp-based insert holding method ensures repeatable seating at seat size 15. Primary workpiece materials include stainless steel, superalloys, and titanium, corresponding to ISO material groups M and S. The MM insert geometry and 870-1550-15-MM 2334 ISO designation identify the exact seat and tip configuration required when ordering or cross-referencing replacement tips for CoroDrill 870 tool bodies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with fine grain microstructure for edge integrity under high cutting loads\u003c\/li\u003e\n\u003cli\u003eAlTiCrN PVD coating provides oxidation resistance and extended tool life on hard-to-machine alloys\u003c\/li\u003e\n\u003cli\u003e142-degree point angle supports stable drill entry and reduced thrust force\u003c\/li\u003e\n\u003cli\u003eHelical, regular-spiral flute design aids chip flow during stainless steel and superalloy drilling\u003c\/li\u003e\n\u003cli\u003eClamp-type insert holding at seat size 15 ensures consistent tip positioning and quick changeover\u003c\/li\u003e\n\u003cli\u003eDesigned for CoroDrill 870 modular system, enabling tip replacement without discarding the drill body\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eThis tip is compatible with CoroDrill 870 series modular drill bodies accepting seat size 15.

Before replacing the tip, ensure the machine spindle is fully stopped and the tool is secured in a fixture or tool holder per shop safety procedures. Use the appropriate clamping torx or hex key as specified by the drill body manufacturer for the seat size 15 interface. Inspect the insert seat for chips or debris before seating the new tip to ensure full contact and accurate runout.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 15.00 mm (0.6102 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 142 degrees\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: 2334\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\u003eInsert Geometry\u003c\/strong\u003e: MM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 15\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\u003eFlute Length\u003c\/strong\u003e: 7.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunctional Length\u003c\/strong\u003e: 0.2728 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.3661 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 9.00 mm\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\u003eSeries\u003c\/strong\u003e: CoroDrill 870\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Number\u003c\/strong\u003e: 870-1550-15-MM 2334\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Solid Drilling\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.018 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 7357779\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51755131633970,"sku":"7357779","price":393.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e03f774baad9444ed6c434b95a22595c_f0703e65-6be8-4da2-a463-b8981854dee5.jpg?v=1788951451","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7357779-replaceable-drill-tip-15mm-grade-2334","provider":"Voomi Supply","version":"1.0","type":"link"}
