Built on an HM90 E90A-10 toolholder platform with a 90-degree lead angle, it accepts AP..1003.. and HM90 AP..1003.. insert styles secured by screw clamping. The cutter body is constructed from solid carbide and features a Weldon flat shank for positive drive and minimal pullout risk. With a 1-inch cutting diameter, 4-flute configuration, and a maximum depth of cut of 0.394 inches, this toolholder is suited for aggressive shoulder milling passes in ferrous and non-ferrous materials. Licensed machinists, CNC operators, and toolroom technicians are the primary users.\u003c\/p\u003e\n\u003cp\u003eThe ISCAR 3101933 is intended for square-shoulder milling applications where a true 90-degree wall angle is required. Its 3\/4-inch Weldon flat shank is compatible with standard Weldon-style end mill holders used on vertical machining centers, horizontal mills, and CNC milling machines. The Heli2000 series is engineered for general-purpose milling in production and job-shop environments. A maximum ramping angle of 2.5 degrees allows for limited helical interpolation entry where direct plunging is not feasible. The toolholder does not feature through-coolant capability, so external coolant delivery or flood cooling should be planned at setup.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e90-degree lead angle produces true square shoulders in a single pass\u003c\/li\u003e\n  \u003cli\u003e4-flute, 4-insert indexable design with screw-clamp insert retention\u003c\/li\u003e\n  \u003cli\u003eAccepts AP..1003.. and HM90 AP..1003.. insert styles for broad insert availability\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank provides positive torque transfer and pullout resistance\u003c\/li\u003e\n  \u003cli\u003eMaximum ramping angle of 2.5 degrees supports helical interpolation entry\u003c\/li\u003e\n  \u003cli\u003eCertified to AS 9100, ISO 9001:2008, and ISO 14001:2004 quality standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with AP..1003.. and HM90 AP..1003.. insert styles.

Secure the toolholder in a Weldon-style end mill holder, tightening the set screw against the flat to the machine tool manufacturer's specification. Inspect insert seats for chips or debris before seating inserts, and confirm screw torque with a calibrated torque driver per the insert manufacturer's guidelines. Verify runout with a dial indicator before commencing a production cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 1 inch\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\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutter Inserts\u003c\/strong\u003e: 4\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: 2.5 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.750 inches (3\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 1.000 inches\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\u003eTool Material\u003c\/strong\u003e: Solid Carbide\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\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\u003eManufacturer Catalog Number\u003c\/strong\u003e: HM90 E90A-D1.00-4-W.75\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Milling\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\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: 3101933\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51727371370802,"sku":"3101933","price":517.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b3b2fb24e4ced66727c3739dc8da277a.jpg?v=1788676887","url":"https:\/\/voomisupply.com\/products\/iscar-3101933-indexable-square-shoulder-end-mill","provider":"Voomi Supply","version":"1.0","type":"link"}
