It features an 18.00 mm (0.7087 inch) cutting diameter with a 142-degree point angle and is manufactured from solid carbide with a fine grain material grade. The AlTiCrN coating is applied via a PVD process, delivering heat and wear resistance suited to demanding cutting conditions. This tip uses a clamp-style insert holding method with a seat size of 18, and is intended for solid drilling applications where repeatable tip replacement reduces downtime and tooling cost.\u003c\/p\u003e\u003cp\u003eThis drill tip is engineered for machining stainless steel, superalloys, and titanium — material codes M and S — making it appropriate for aerospace, medical, energy, and general precision manufacturing environments. It is used in CNC machining centers where the CoroDrill 870 body is already mounted. The helical, regular spiral flute configuration with two flutes provides controlled chip evacuation during through-hole and blind-hole solid drilling operations. Coolant-through capability is not supported on this tip.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e18.00 mm cutting diameter with 142-degree standard point angle for accurate entry and reduced thrust force\u003c\/li\u003e\n\u003cli\u003eSolid carbide fine grain substrate for rigidity and edge integrity in tough workpiece materials\u003c\/li\u003e\n\u003cli\u003eAlTiCrN PVD coating for high-temperature wear resistance when cutting stainless steel, superalloys, and titanium\u003c\/li\u003e\n\u003cli\u003eTwo helical flutes with regular spiral for consistent chip flow in solid drilling operations\u003c\/li\u003e\n\u003cli\u003eClamp-type insert holding with seat size 18 for secure, repeatable tip indexing on CoroDrill 870 bodies\u003c\/li\u003e\n\u003cli\u003eISO number 870-1800-18-MM 2334 for straightforward cross-reference and ordering\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with SANDVIK COROMANT CoroDrill 870 series modular drill bodies accepting insert seat size 18.

The machine spindle must be fully stopped and the tool assembly secured before tip removal or installation. Use the correct clamping key or torx driver specified for the CoroDrill 870 seat to avoid seat damage — do not use improvised tooling. Inspect the insert seat for debris or damage before seating the new tip to ensure proper contact and runout performance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Number\u003c\/strong\u003e: 870-1800-18-MM 2334\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroDrill 870\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 18.00 mm (0.7087 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\u003ePoint Type\u003c\/strong\u003e: Standard\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: 18\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, Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 9.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunctional Length\u003c\/strong\u003e: 0.3378 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length \/ Projection\u003c\/strong\u003e: 0.4449 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 11.00 mm (5.51 inches per package dimension)\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 \/ Finish\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\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\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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.029 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: 7357893\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51729363206450,"sku":"7357893","price":218.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f5aab03d00ff712ae1c2a8848bd42ff6_b64060d9-3b08-447b-a33b-5ced743e7548.jpg?v=1788703570","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7357893-replaceable-drill-tip-18mm","provider":"Voomi Supply","version":"1.0","type":"link"}
