This HM90 E90A-10 toolholder features a 0.75-inch cutting diameter, a 90-degree lead angle, and a maximum depth of cut of 0.394 inches. Built from solid carbide with a Weldon flat shank, it accepts AP..1003.. series inserts secured by screw clamping. With a 3.38-inch overall length and a 2-flute configuration, it is suited for demanding square-shoulder milling applications requiring tight tolerances and consistent chip evacuation. Installation and use are handled by machinist and toolroom professionals.\u003c\/p\u003e\u003cp\u003eThis end mill is used in production machining and toolroom environments where square-shoulder profiles and precise radial engagement are required. The Heli2000 series is engineered for high-feed milling on steel, stainless, cast iron, and similar materials. The 0.75-inch Weldon flat shank provides secure seating in compatible tool holders, reducing pull-out risk during interrupted cuts or high-feed passes. The 90-degree lead angle promotes clean shoulder formation and minimizes axial forces on the spindle. No coolant-through capability is present on this toolholder.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.75-inch cutting diameter with 0.394-inch maximum depth of cut\u003c\/li\u003e\n\u003cli\u003e90-degree lead angle for true square-shoulder milling\u003c\/li\u003e\n\u003cli\u003eWeldon flat shank for positive anti-pull-out seating in the tool holder\u003c\/li\u003e\n\u003cli\u003eAccepts AP..1003.. and HM90 AP..1003.. insert styles, screw-clamped\u003c\/li\u003e\n\u003cli\u003e2-flute, 2-insert configuration for balanced cutting forces\u003c\/li\u003e\n\u003cli\u003eCertified to AS 9100, ISO 9001:2008, ISO 14001:2004, ISO 50001, and OHSAS 18001:2007\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with AP..1003.. and HM90 AP..1003.. series inserts.

Ensure the machine spindle is fully powered down and locked out before mounting or changing inserts. Secure the Weldon flat shank in the tool holder to the appropriate interface specification using a side-lock set screw. Follow the insert manufacturer torque guidance for screw-clamped inserts when seating AP..1003.. style inserts to avoid over-torquing the clamping screw.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.394 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3.38 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.25 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutter Inserts\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Style\u003c\/strong\u003e: HM90 E90A-10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: AP..1003.., HM90 AP..1003..\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Heli2000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCatalog Number\u003c\/strong\u003e: HM90 E90A-D.75-2-W.75\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\u003eApplication\u003c\/strong\u003e: Milling\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: 3101948\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51736756814130,"sku":"3101948","price":442.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/806ab2f0d55e841f4b20bb2cfb7e5aff.jpg?v=1788779993","url":"https:\/\/voomisupply.com\/products\/iscar-3101948-indexable-square-shoulder-end-mill","provider":"Voomi Supply","version":"1.0","type":"link"}
