It carries a 3\/8-inch cutting diameter and a 0.0150-inch corner radius, with a 1-inch length of cut and a 2.5-inch overall length. The tool is coated with AlTiN via a PVD process, providing thermal resistance and extended tool life at elevated cutting speeds. A 38-degree medium helix and close-pitch flute geometry support both roughing and finishing passes. Centercutting capability allows plunge entry. The straight cylindrical shank measures 3\/8 inch in diameter, fitting standard toolholders used in CNC milling operations.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for machining steel, stainless steel, cast iron, superalloys, and titanium in professional shop and production environments. Its stub-length profile and right-hand cutting and flute direction make it appropriate for rigid setups where tool deflection must be minimized. It is a single-end tool from the SECO S638R series, intended for use with standard toolholders in vertical and horizontal machining centers. Machinists working on aerospace, die-and-mold, and general metalworking applications will find this geometry well matched to tight-tolerance finishing and controlled roughing in hard and abrasion-resistant materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlTiN PVD coating provides heat resistance for dry and high-speed cutting in ferrous and hard materials\u003c\/li\u003e\n  \u003cli\u003e6-flute, close-pitch design increases feed rates and surface finish quality compared to lower flute counts\u003c\/li\u003e\n  \u003cli\u003e0.0150-inch corner radius reduces stress concentration at cutting corners and extends tool life on hardened materials\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge milling without pre-drilled entry holes\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide construction provides rigidity and wear resistance in abrasive workpiece materials\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flutes with medium helix angle balance chip evacuation and cutting stability\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 3\/8-inch cylindrical shank.

Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the toolholder. Confirm shank seating depth and toolholder runout before initiating cuts; maximum TIR for this tool is 0.0005 inch. Do not exceed the toolholder manufacturer's recommended clamping torque specifications, and verify coolant-through is not required, as this tool does not support through-spindle coolant.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch (1.0000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0150 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\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, Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\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\u003ePitch\u003c\/strong\u003e: Close\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 Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys and Titanium\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: 0.14 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.5 x 0.7 x 0.7 inches\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: 03007643\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51563971674418,"sku":"03007643","price":137.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cc6a1594f36b27e868d590530a232022_92a81bec-7852-489b-b021-d591b104ba96.jpg?v=1786508319","url":"https:\/\/voomisupply.com\/products\/seco-03007643-corner-radius-end-mill-3-8-in-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
