Built on the HEV-C-7 series platform, it features a variable-pitch flute geometry and integrated chipbreaker design that reduce harmonic vibration and improve chip evacuation during aggressive material removal. The 0.03-inch corner radius protects the cutting edge at entry and exit while maintaining a consistent profile in the workpiece. APLUS PVD coating provides thermal and wear resistance suited for dry or semi-dry cutting environments. This tool is intended for use in professional CNC machining operations.\u003c\/p\u003e\n\u003cp\u003eThis end mill is engineered for roughing operations in steel, stainless steel, cast iron, superalloys, and titanium — material application codes P, M, K, and S. It also handles non-ferrous metals as a secondary application. The single-end, centercutting configuration supports plunge, slot, and peripheral milling. Right-hand flute direction and right-hand cutting orientation are standard. The straight-cylindrical shank is sized for high-precision toolholders and collet systems. It is suited for production environments running tight tolerances on machining centers with rigid setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7-flute variable-pitch geometry reduces chatter and supports higher feed rates in roughing passes\u003c\/li\u003e\n  \u003cli\u003eChipbreaker design promotes chip segmentation and clearance in deep cuts\u003c\/li\u003e\n  \u003cli\u003e0.03-inch corner radius extends edge life and reduces stress concentration at cut entry\u003c\/li\u003e\n  \u003cli\u003eAPLUS PVD coating delivers elevated hardness and oxidation resistance for ferrous machining\u003c\/li\u003e\n  \u003cli\u003eCentercutting capability allows direct plunge entry without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction maintains rigidity and dimensional stability at elevated cutting speeds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with high-precision toolholders. Primary workpiece materials include low-alloy steel, medium alloy steel, tool steel, cast iron, and titanium. Secondary workpiece material compatibility includes non-ferrous metals.

Seat the straight-cylindrical shank fully into a high-precision collet or shrink-fit toolholder and verify runout does not exceed the 0.0005-inch TIR maximum before cutting. Confirm spindle direction matches the right-hand cutting orientation before engaging the workpiece. Do not exceed the rated length of cut of 1.25 inches; extended axial engagement beyond this depth can cause deflection and premature edge failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.030 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: -0.0020 to +0.0020 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.0020 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: -0.0620 to +0.0620 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR Maximum\u003c\/strong\u003e: 0.0005 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\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\u003ePitch\u003c\/strong\u003e: Variable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HEV-C-7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.265 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: 59428\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51752920514866,"sku":"59428","price":188.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2858d4771745ab9247fc82e6a5af2123_89f41033-1067-4bb3-afc6-1f8718bb83ce.jpg?v=1788931123","url":"https:\/\/voomisupply.com\/products\/helical-solutions-59428-corner-radius-end-mill-1-2-in-7-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
