The tool features a 5\/8 inch cutting diameter, a maximum depth of cut of 0.303 inches, and a 90-degree lead angle that produces true square shoulders in a single pass. With through-coolant capability, it supports aggressive material removal while managing heat at the cutting zone. Installation and setup are handled by machinists and CNC operators in production and job-shop environments. The HP E90AN-07 toolholder cutter style accepts HP AN.. 0702.. insert style inserts, which are secured via screw-type insert holding.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling operations requiring square-shoulder profiles on ferrous and non-ferrous materials. The Heliplus series targets applications where consistent insert indexing and thermal control are priorities, such as aerospace component machining, mold work, and general production milling. The 3-flute, 3-insert configuration balances cutting forces and chip evacuation across a range of feed rates and depths of cut. The cylindrical shank allows direct mounting in standard ER or side-lock toolholders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e90-degree lead angle for true square-shoulder milling in a single pass\u003c\/li\u003e\n\u003cli\u003eThrough-coolant design channels fluid directly to the cutting zone for improved tool life and chip control\u003c\/li\u003e\n\u003cli\u003e3-flute, 3-insert configuration using HP AN.. 0702.. insert style with screw-type holding\u003c\/li\u003e\n\u003cli\u003eHP E90AN-07 cutter style designation for straightforward toolholder and insert selection\u003c\/li\u003e\n\u003cli\u003eHeliplus series construction meets AS 9100, ISO 9001:2008, ISO 14001:2004, ISO 50001, and OHSAS 18001:2007 standards\u003c\/li\u003e\n\u003cli\u003eCylindrical shank for compatibility with standard toolholding systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with the HP E90AN-07 toolholder cutter style and HP AN.. 0702.. insert style inserts.

Before mounting or removing the tool, ensure the machine spindle is fully stopped and the machine is in a safe state per shop lockout\/tagout procedures. Verify toolholder runout and insert seating before cutting. Coolant supply lines should be confirmed open and at operating pressure before engaging through-coolant mode.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 5\/8 inches (0.625 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.303 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inches (0.625 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 1.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutter Inserts\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: HP AN.. 0702..\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Style\u003c\/strong\u003e: HP E90AN-07\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Heliplus\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Milling\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturers Catalog Number\u003c\/strong\u003e: HP E90AN-D.62-3-C.62-7C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: AS 9100, ISO 9001:2008, ISO 14001:2004, ISO 50001, OHSAS 18001:2007\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 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: ISCAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3181028\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51732897595698,"sku":"3181028","price":445.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5a700c74b33f743ee237f18d9f01b537.jpg?v=1788748348","url":"https:\/\/voomisupply.com\/products\/iscar-3181028-indexable-square-shoulder-end-mill","provider":"Voomi Supply","version":"1.0","type":"link"}
