With a 3\/4 inch cutting diameter and a 0.0600 inch corner radius, it delivers a controlled blend between the side wall and floor of a milled feature, reducing stress concentrations in finished parts. The 6-flute, right-hand spiral geometry supports both roughing and finishing operations in a single tool. An AlTiN (PVD) coating provides thermal resistance and surface hardness suited to dry or semi-dry cutting conditions. Licensed machinists and CNC operators in job shop, aerospace, and production machining environments are the primary users of this tool.\u003c\/p\u003e\u003cp\u003eThis end mill is engineered for use in steel, stainless steel, cast iron, superalloys, and titanium — material application codes P, M, K, and S. The stub length profile and straight cylindrical shank make it compatible with standard toolholders used on vertical and horizontal machining centers. The close pitch, 6-flute configuration allows higher feed rates per tooth in materials where chip evacuation is manageable, making it a practical choice for finish-quality floor passes or light profiling cuts in tough alloys.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide micrograin substrate for rigidity and edge retention in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eAlTiN PVD coating enhances heat resistance and tool life in ferrous and superalloy cutting\u003c\/li\u003e\n\u003cli\u003e0.0600 inch corner radius reduces chipping at the cutting edge and improves part surface finish\u003c\/li\u003e\n\u003cli\u003e6-flute close-pitch design supports aggressive feed rates in finishing and light roughing passes\u003c\/li\u003e\n\u003cli\u003e38-degree helix angle provides smooth chip flow and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capability allows plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003eSeries S638R stub-length geometry minimizes deflection in tight-reach applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard straight-bore toolholders on CNC machining centers.

Secure the straight cylindrical shank in a clean, properly sized toolholder bore and torque to the toolholder manufacturer specification. Verify runout against the stated TIR maximum of 0.0005 inches before beginning a cut. Do not exceed the recommended depth of cut or feed rates for the workpiece material, and confirm cutting parameters are appropriate for the coating type before running dry or with coolant.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eLength of Cut\u003c\/strong\u003e: 1-3\/4 inch (1.7500 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: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0600 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN (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\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Close\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\u003eTIR Maximum\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: +0.00100 to -0.00100 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\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001\/-0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: -0.0600\/0.0600 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys and Titanium\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\u003eSeries\u003c\/strong\u003e: S638R\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.8 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 5.5 x 1.1 x 1.1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 03007660\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51563804229938,"sku":"03007660","price":548.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cc6a1594f36b27e868d590530a232022_6526b0cd-928b-4ab3-9bb6-634edeee4c6e.jpg?v=1786503836","url":"https:\/\/voomisupply.com\/products\/seco-03007660-corner-radius-end-mill-3-4-in-6-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
