It features a 3\/4 inch mill diameter, a 2-1\/4 inch length of cut, and a 5 inch overall length with a 3\/4 inch straight cylindrical shank. The tool carries an APLUS PVD coating engineered for wear resistance in ferrous materials. A variable index flute geometry reduces harmonic vibration during aggressive cuts, making it suitable for both roughing and finishing passes. This end mill is intended for use by machinists and tool-and-die professionals operating CNC machining centers.\u003c\/p\u003e\n\u003cp\u003eThis end mill is well-suited for milling steel alloys, tool steels, stainless steel, and cast iron in production or job-shop environments. The single-end, right-hand cutting configuration is standard for CNC vertical and horizontal machining centers. The 2-1\/4 inch reach length supports moderate-depth cavity work, profiling, and contouring operations where a ball nose profile is required. It is classified under ISO material groups P, M, and K, covering a broad range of ferrous workpiece materials encountered in industrial machining.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and heat resistance in ferrous machining\u003c\/li\u003e\n  \u003cli\u003eAPLUS PVD coating improves lubricity and extends tool life in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eVariable index flute spacing reduces chatter and vibration during cutting\u003c\/li\u003e\n  \u003cli\u003eBall nose profile with 0.375 inch nose radius for profiling and contouring\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand spiral, compatible with standard CNC spindle rotation\u003c\/li\u003e\n  \u003cli\u003eRated for both roughing and finishing material removal in a single tool\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on CNC machining centers with standard straight-bore tool holders accepting a 3\/4 inch shank.

Ensure the machine spindle is fully stopped and the tool changer is in a safe state before installing or removing the end mill. Seat the shank fully into the tool holder to the recommended gauge-line depth and verify TIR does not exceed 0.0005 inches as specified. Follow all applicable shop safety procedures and machine-builder guidelines when setting tool offsets and feeds.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 2.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches (5.0000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.3750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: APLUS (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron (ISO P, M, K)\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 \/ -0.0020 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.0620 \/ -0.0620 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum TIR\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.928 pounds\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: HELICAL SOLUTIONS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 56677\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51747391930674,"sku":"56677","price":433.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e9c8bc55c4f31badf2181f4032989dca_945f3932-c384-4a1c-847a-038e06900f06.jpg?v=1788879350","url":"https:\/\/voomisupply.com\/products\/helical-solutions-56677-ball-end-mill-3-4-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
