Built on an HM390 ETP-10 toolholder platform with a 1-1\/2 inch cutting diameter and a 90-degree lead angle, this tool delivers true square-shoulder profiles with consistent wall accuracy. The Weldon flat shank measures 1 inch in diameter and 2.75 inches in length, providing positive drive retention in the spindle. Through-coolant capability keeps the cutting zone clear and extends insert life during demanding material removal. The body is constructed from solid carbide and accepts HM390 TPKT 1003 inserts secured by screw clamping. Five helical flutes provide smooth chip evacuation and stable cutting engagement across a range of workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for square-shoulder milling, slotting within its 0.315 inch maximum depth of cut, and light ramping at up to 1.6 degrees. Typical applications include face milling, shoulder milling, and pocket milling on ferrous and non-ferrous metals in aerospace, general machining, and precision job shop environments. The HeliIQMill platform is a common choice in CNC vertical and horizontal machining centers where indexable tooling reduces per-edge cost compared to solid end mills. The tool is compliant with AS 9100 quality standards, making it appropriate for aerospace supply chain work where material and process traceability are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/2 inch cutting diameter with a 90-degree lead angle for true square-shoulder profiles\u003c\/li\u003e\n  \u003cli\u003eFive helical flutes for smooth chip flow and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design directs fluid directly to the cutting edge\u003c\/li\u003e\n  \u003cli\u003eHM390 TPKT 1003 insert compatibility with screw-lock clamping for secure insert retention\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank provides positive anti-pullout drive in the holder\u003c\/li\u003e\n  \u003cli\u003eMaximum ramping angle of 1.6 degrees supports controlled plunge entry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with HM390 TPKT 1003 inserts.

Confirm holder bore condition and Weldon set-screw torque before running. Do not exceed the published maximum depth of cut or ramping angle for this toolholder series, as overloading indexable tooling can cause insert fracture or body damage. Inspect inserts for wear or chipping at regular intervals and replace using the correct Torx or hex key per ISCAR insert seating procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.315 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutter Inserts\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Ramping Angle\u003c\/strong\u003e: 1.6 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Style\u003c\/strong\u003e: HM390 ETP-10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: HM390 TPKT 1003\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HeliIQMill\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.637 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: AS 9100, ISO 14001:2004, ISO 50001, ISO 9001:2008, OHSAS 18001:2007\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: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3106633\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51997855777074,"sku":"3106633","price":624.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2c7fbea51c7535ddf79220b5fcb5e3d1.jpg?v=1789994427","url":"https:\/\/voomisupply.com\/products\/iscar-3106633-indexable-square-shoulder-end-mill","provider":"Voomi Supply","version":"1.0","type":"link"}
