It carries a 0.030 inch corner radius, a 0.5 inch mill diameter, and a 1.25 inch length of cut. The Tplus PVD coating provides elevated wear resistance and thermal protection during aggressive cutting cycles. Variable pitch geometry reduces harmonic chatter, which is critical when machining difficult materials at high spindle speeds. This tool is suited for machinists and CNC operators working in precision manufacturing, aerospace, medical, and general job shop environments.\u003c\/p\u003e\u003cp\u003eThe 59957 is built for both roughing and finishing passes in a single tool, reducing the need to change tools mid-operation. With a 3 inch overall length and a 0.5 inch straight cylindrical shank, it seats directly in high-precision toolholders such as shrink-fit, hydraulic, or high-accuracy collet chucks. Primary workpiece materials are stainless steel, high-temperature alloys, and hardened steels. Secondary workpiece materials include general steel and cast iron. The single-end, right-hand cutting geometry is standard for conventional CNC vertical and horizontal machining center setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7-flute variable pitch design reduces chatter and vibration in hard and exotic materials\u003c\/li\u003e\n\u003cli\u003eTplus PVD coating rated for stainless steel, high-temperature alloy, and hardened steel applications\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction delivers rigidity and dimensional stability under high cutting loads\u003c\/li\u003e\n\u003cli\u003e0.030 inch corner radius extends tool life and improves surface finish at workpiece corners\u003c\/li\u003e\n\u003cli\u003eRated for both roughing and finishing material removal in a single tool\u003c\/li\u003e\n\u003cli\u003e0.0005 inch maximum TIR ensures repeatable accuracy in high-precision toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with high-precision toolholders including shrink-fit, hydraulic, and high-accuracy collet chuck systems.

The shank diameter tolerance is h6, so toolholder bore cleanliness and runout verification are required before seating. Confirm toolholder TIR meets or exceeds the 0.0005 inch maximum TIR specification for this tool. Power down the spindle and follow lockout\/tagout procedures before inserting or removing the end mill from the holder.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 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: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 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\u003eMaximum TIR\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: 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\u003eFlute Type\u003c\/strong\u003e: Spiral\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\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\u003eExtended Reach\u003c\/strong\u003e: No\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\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: 0.267 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: 59957\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51743406489906,"sku":"59957","price":191.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c51691bcd97ee5e467395a9a5211e64d_ed7404eb-6513-45dc-bda2-65735990d9e3.jpg?v=1788846714","url":"https:\/\/voomisupply.com\/products\/helical-solutions-59957-corner-radius-end-mill-7-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
