This single-end tool features a 3\/8 inch mill diameter, a 7-flute configuration with variable flute spacing (super close pitch), and a 45-degree chamfer angle with a 0.0050 inch chamfer width. The AlTiN PVD coating provides thermal resistance and extended tool life when cutting hard and abrasive materials. At 3.5 inches overall length with a 1.5 inch length of cut, it is sized for reach-demanding applications. Installation and operation are performed by machinists and CNC programmers in job shop and production environments.\u003c\/p\u003e\u003cp\u003eThis end mill is engineered for use on steel, stainless steel, cast iron, superalloys, and titanium workpiece materials (material codes P, M, K, S). It supports a wide range of machining operations including shouldering, slotting, ramp-down entry, helical interpolation, drill milling, plunging, and recessing. The right-hand cutting direction and right-hand flute orientation make it compatible with standard CNC machining center spindles. The medium helix style and micrograin carbide substrate suit both roughing and finishing passes on difficult-to-machine alloys. This tool belongs to the SECO S738 series.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7-flute variable-index design with super close pitch for improved surface finish and reduced chatter\u003c\/li\u003e\n\u003cli\u003e45-degree chamfer angle with 0.0050 inch chamfer width and 0.0050 inch chamfer length\u003c\/li\u003e\n\u003cli\u003eAlTiN PVD coating for heat resistance in dry and hard-material cutting applications\u003c\/li\u003e\n\u003cli\u003eSolid micrograin carbide substrate supports both roughing and finishing material removal\u003c\/li\u003e\n\u003cli\u003eSupports shouldering, slotting, ramp-down, helical interpolation, drill milling, plunging, and recessing\u003c\/li\u003e\n\u003cli\u003eMaximum TIR of 0.0005 inch ensures precision runout control\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003ePrimary workpiece materials include steel, stainless steel, cast iron, superalloys, and titanium (ISO material codes P, M, K, S).

Verify spindle direction is set to right-hand rotation before use. Confirm toolholder runout is within acceptable limits prior to cutting, as micrograin carbide is sensitive to vibration and improper clamping. Follow machine manufacturer guidelines and applicable shop safety procedures when loading or unloading cutting tools.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.3750 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: 1.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Width\u003c\/strong\u003e: 0.0050 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: Medium\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: Super Close\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Variable\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0020 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\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: S738\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.18 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: 17002327\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51557638111538,"sku":"17002327","price":148.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d2ca06f3aa2194be0afdd2f5edac28dd.jpg?v=1786391763","url":"https:\/\/voomisupply.com\/products\/seco-17002327-corner-chamfer-end-mill-3-8-in-7-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
