The tool features a 7\/16 inch (0.4375 inch) diameter, a 0.030 inch corner radius, and five flutes with a 45-degree high helix angle. An AlTiN PVD coating increases surface hardness and heat resistance, extending tool life in abrasive and high-temperature cutting environments. The single-end, centercutting design allows for both plunge and peripheral cutting. This end mill is built for use in toolholders with a straight-cylindrical shank and is suited to production and job-shop finishing applications on difficult-to-machine workpiece materials.\u003c\/p\u003e\u003cp\u003eThe 17007020 is engineered for finishing cuts in steel, stainless steel, superalloys, titanium, and hard materials. Its short flute length and normal pitch make it well-suited to rigid setups where dimensional accuracy and surface finish are priorities. The 5-flute geometry improves feed rates compared to standard 4-flute tooling, while the right-hand cutting and right-hand spiral flute direction are consistent with conventional CNC milling setups. This tool is used in CNC machining centers across aerospace, medical, die-and-mold, and general precision manufacturing environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eAlTiN PVD coating provides high heat resistance and extended tool life in steel, stainless, and superalloys\u003c\/li\u003e\n\u003cli\u003e5-flute design improves chip clearance and enables higher feed rates during finishing passes\u003c\/li\u003e\n\u003cli\u003e0.030 inch corner radius reduces stress concentrations and improves edge strength on milled profiles\u003c\/li\u003e\n\u003cli\u003e45-degree high helix angle promotes smooth cutting action and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry permits direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eSeries S545R with tight corner radius tolerance of plus or minus 0.001 inch for precision fitment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard toolholders accepting a 7\/16 inch straight-cylindrical shank.

Ensure the toolholder bore and collet are clean and free of debris before seating the shank. Confirm runout does not exceed the rated TIR maximum of 0.0005 inch after installation. Verify spindle speed, feed rate, and depth of cut parameters against the applicable SECO S545R series cutting data before starting the program.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 7\/16 inch (0.4375 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7\/16 inch (0.4375 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0300 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: plus 0.00100 to minus 0.00100 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.0020 \/ 0.0000 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: -0.0600 \/ +0.0600 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR Maximum\u003c\/strong\u003e: 0.0005 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN (PVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Short\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Finishing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys and Titanium, Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: S545R\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: SECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 17007020\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51562720624946,"sku":"17007020","price":153.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bdfd18e2e84f998028308168b3c643a8_77929baf-6b49-44fb-8171-50569e88c0de.jpg?v=1786483053","url":"https:\/\/voomisupply.com\/products\/seco-17007020-corner-radius-end-mill-7-16-in-5-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
