Built on the HEV-7 series platform, it features a 0.5 inch mill diameter, a 1.625-inch length of cut, and a 0.0300-inch corner radius with a tight tolerance of -0.0020 to 0.0020 inches. The Tplus PVD coating enhances wear resistance and thermal stability. Variable pitch geometry reduces harmonic vibration during aggressive cuts. This tool is engineered for machinists running stainless steel, high-temperature alloys, and hardened steel on CNC machining centers where both roughing and finishing passes are required.\u003c\/p\u003e\u003cp\u003eThe 59958 is suited for precision CNC milling applications in aerospace, medical, die and mold, and general precision machining shops. It excels in materials classified under ISO material groups M (stainless steel), S (high-temperature alloy), and H (hard material), with secondary capability in P (steel) and K (cast iron). The single-end design and straight cylindrical shank pair well with high-precision toolholders such as shrink-fit or hydraulic chuck systems. The 4-inch overall length provides adequate reach for most standard fixturing setups without compromising rigidity.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7-flute geometry supports both roughing and finishing in a single tool\u003c\/li\u003e\n\u003cli\u003eVariable pitch eliminates chatter and reduces harmonics at aggressive feed rates\u003c\/li\u003e\n\u003cli\u003eTplus PVD coating for extended tool life in abrasive and hard materials\u003c\/li\u003e\n\u003cli\u003e0.0300-inch corner radius reduces stress concentration at the cutting edge\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand spiral flute direction for standard CNC setups\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for stiffness and thermal resistance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with high-precision toolholders.

Secure the shank in a high-precision toolholder to the toolholder manufacturer's specified runout requirements — TIR maximum for this tool is 0.0005 inches. Confirm spindle orientation and cut direction match the right-hand configuration of this end mill before initiating the program. Do not exceed the tool manufacturer's recommended speeds and feeds for the target workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5000 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: 1.6250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0300 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\u003eOverall Length\u003c\/strong\u003e: 4.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5000 inches\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\u003eSingle or Double End\u003c\/strong\u003e: Single\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: Tplus (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\u003eCentercutting\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR Maximum\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.0020\/0.0000 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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel; High-Temperature Alloy; Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Steel; Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HEV-7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.357 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: HELICAL SOLUTIONS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 59958\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51738575733042,"sku":"59958","price":227.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c51691bcd97ee5e467395a9a5211e64d_0af568f9-66cd-4da5-ac09-c38dde3b87a1.jpg?v=1788801206","url":"https:\/\/voomisupply.com\/products\/helical-solutions-59958-corner-radius-end-mill-1-2-in-7-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
