It features a 3\/8 inch cutting diameter, a 3\/8 inch length of cut, and a 38-degree helix angle with AlTiN coating applied via PVD process. The micrograin carbide substrate and AlTiN finish deliver thermal resistance and hardness retention at elevated cutting temperatures. Variable index geometry reduces chatter and improves surface finish. This tool is suited for machinists and CNC operators running steel, stainless steel, cast iron, and high-temperature alloys.\u003c\/p\u003e\n\u003cp\u003eThe 03115946 is configured as a single-end, right-hand cutting, right-hand flute tool with a straight cylindrical shank and stub-length profile. It is intended for roughing operations in ferrous and exotic alloy materials. The 2 inch overall length and compact stub geometry make it well suited for applications requiring rigidity with limited stick-out. It fits standard 3\/8 inch tool holders and collet chucks common in CNC machining centers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e6-flute design increases feed rate capability and material removal in roughing operations\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating (PVD process) provides high heat resistance for dry and semi-dry cutting in hard materials\u003c\/li\u003e\n  \u003cli\u003e38-degree medium helix angle balances chip evacuation and cutting force\u003c\/li\u003e\n  \u003cli\u003eVariable index flute spacing reduces harmonic vibration and chatter\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate maintains edge integrity in steel, stainless steel, cast iron, and high-temp alloys\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capable; right-hand cut and flute direction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in steel (P), stainless steel (M), cast iron (K), and high-temperature alloys (S) per ISO material codes.

Ensure the spindle is fully stopped and the machine is in a safe state before loading or unloading the tool. Verify runout does not exceed the specified TIR maximum of 0.0005 inches using a dial indicator at setup. Follow the machine manufacturer and tooling guidelines for appropriate speeds, feeds, and clamping torque for 3\/8 inch carbide end mills.\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 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\u003eNose Radius\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 \/ -0.0020 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\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR Maximum\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SB638\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\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: 03115946\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51562550624562,"sku":"03115946","price":136.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a744921c3bc61c61d17e061d72edc43b_f25bb2e3-0e37-4d26-8737-7242d934e46b.jpg?v=1786479491","url":"https:\/\/voomisupply.com\/products\/seco-03115946-ball-end-mill-3-8-in-6-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
