The tool measures 1 inch in diameter with a 2-inch length of cut, a 5-inch overall length, and a 0.0600-inch corner radius. The 6-flute, right-hand spiral geometry runs at a medium 38-degree helix angle and is finished with an AlTiN (aluminum titanium nitride) PVD coating for extended tool life at elevated cutting temperatures. This end mill is center-cutting and rated for both roughing and finishing operations, making it a versatile choice for machinists working in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for CNC milling centers and manual mills where close-pitch, multi-flute tooling is required to achieve fine surface finishes on ferrous and exotic workpiece materials. The straight-cylindrical 1-inch shank seats directly into standard toolholders. The S638R series designation indicates a stub-length configuration, which improves rigidity and reduces deflection in deep-pocketing and shoulder-milling applications on steel and superalloy components. It is intended for use by machinists and tool-and-die professionals working on precision parts in aerospace, energy, and general manufacturing applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide micrograin substrate provides hardness and wear resistance in difficult-to-machine alloys\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating supports high-speed dry and semi-dry cutting in steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003e6-flute close-pitch design increases feed rates and improves surface finish compared to 4-flute equivalents\u003c\/li\u003e\n  \u003cli\u003e0.0600-inch corner radius reduces stress concentration and chipping at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting geometry allows direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute spiral with medium 38-degree helix balances chip evacuation and radial forces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard straight-bore toolholders accepting a 1-inch cylindrical shank. Compatible workpiece materials include steel, stainless steel, cast iron, superalloys, and titanium (material codes P, M, K, and S).\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following the toolholder manufacturer's runout and clamping torque specifications. Verify TIR at setup — the maximum specified TIR for this tool is 0.0005 inches; excess runout accelerates edge wear and degrades corner radius geometry. Ensure the shank is fully seated and clean before clamping. Confirm spindle speed, feed rate, and depth of cut against SECO published cutting data for the S638R series before first use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\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\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\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\u003eCenter Cutting\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\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\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\u003eSeries\u003c\/strong\u003e: S638R\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.7 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 03007666\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559614611762,"sku":"03007666","price":688.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cc6a1594f36b27e868d590530a232022_dcda6fa0-e102-49cf-9dd9-8d87796f07ab.jpg?v=1786436489","url":"https:\/\/voomisupply.com\/products\/seco-03007666-corner-radius-end-mill-1in-6-flute-altin-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
