Built to the Series 1035 specification, it features a 3\/4 inch cutting diameter, a 2-1\/4 inch length of cut, and a 0.03 inch corner radius that protects part edges and reduces stress concentrations at the cutting tip. With five flutes, variable helix, and variable index geometry, this tool is suited for both roughing and finishing passes. The nACo (FX1) coating extends tool life when working in abrasive and high-temperature materials. Overall length is 5 inches with a 3\/4 inch straight cylindrical shank held to h6 tolerance.\u003c\/p\u003e\u003cp\u003eThis end mill is engineered for use on steel, stainless steel, cast iron, superalloys, titanium, and hard materials. The centercutting geometry allows plunge entry, making it versatile for slotting, profiling, and pocket milling operations. It is a single-end, right-hand cut tool with right-hand flute direction and is compatible with standard end mill toolholders. Machinists and tool-and-die professionals running CNC mills or machining centers will find this tool well suited to tight-tolerance work in difficult alloys.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.03 inch corner radius reduces edge chipping and stress concentration at the cutting tip\u003c\/li\u003e\n\u003cli\u003eVariable helix and variable index geometry reduce harmonics and chatter during aggressive cuts\u003c\/li\u003e\n\u003cli\u003enACo (FX1) coating improves wear resistance in steel, superalloys, and hard materials\u003c\/li\u003e\n\u003cli\u003eCentercutting design permits direct plunge milling without a pre-drilled entry hole\u003c\/li\u003e\n\u003cli\u003eSubmicron carbide grade delivers fine grain structure for sharp edges and long tool life\u003c\/li\u003e\n\u003cli\u003eFive-flute configuration balances chip evacuation with feed rate capability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard end mill toolholders.

Ensure the machine spindle is fully stopped and the toolholder is clean and free of debris before seating the shank. The h6 shank tolerance is intended for precision collet or hydraulic toolholder systems  -  confirm holder bore size matches the 3\/4 inch shank diameter before clamping. Follow machine tool manufacturer torque specifications for the toolholder style in use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.03 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 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\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees, Variable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Submicron Grade)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: nACo \/ FX1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\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: 1035\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Cast Iron, Superalloys, Titanium, Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: GWS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 120977\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GWS","offers":[{"title":"Default Title","offer_id":51984105439538,"sku":"120977","price":490.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/07ccb27a3bfbf1e9f3933edd6a98bc84_39834fb9-d967-411f-8f79-c4b92f793d89.jpg?v=1789984536","url":"https:\/\/voomisupply.com\/products\/gws-120977-corner-radius-end-mill-3-4-in-5-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
