It features a 3\/8 inch cutting diameter, a 1 inch length of cut, and a 3\/8 inch straight-cylindrical shank with an overall length of 2.5 inches. Six spiral flutes with a 38-degree helix angle and a variable index geometry improve chip evacuation and reduce chatter during aggressive cuts. The AlTiN coating adds thermal resistance and surface hardness, extending tool life in ferrous and high-temp alloy applications. This tool is centercutting, allowing direct plunge entry. It is intended for use by machinists and CNC operators in job shop and production environments.\u003c\/p\u003e\u003cp\u003eThe SECO 03007642 is suited for peripheral and slot milling operations in ferrous metals, hardened steels, stainless, and similar materials where heat generation and tool wear are primary concerns. The single-end, right-hand cut and right-hand flute configuration make it compatible with standard vertical and horizontal CNC milling setups. The micrograin carbide substrate provides the toughness and edge retention needed for high-speed finishing and semi-finishing passes. It carries the Series S638 designation within the SECO solid carbide end mill line.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/8 inch cutting diameter with 1 inch length of cut for controlled radial engagement\u003c\/li\u003e\n\u003cli\u003e6 spiral flutes at a 38-degree helix angle for improved chip flow and surface finish\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces harmonics and chatter in deep cuts\u003c\/li\u003e\n\u003cli\u003eAlTiN coating provides oxidation resistance and extended tool life in high-temp alloys\u003c\/li\u003e\n\u003cli\u003eCentercutting design permits direct plunge milling without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for hardness and wear resistance at elevated cutting speeds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling addition for CNC milling machines and manual mills accepting a 3\/8 inch straight-cylindrical shank with ER, side-lock, or shrink-fit collet systems.

Ensure the spindle is fully stopped and the machine is in an e-stop or powered-down state before changing tooling. Verify collet size and runout tolerance before torquing the tool holder to the spindle per the machine manufacturer specification. Do not exceed the tool overhang length beyond what is needed for the operation, as excess overhang reduces rigidity and accelerates wear.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.060 \/ -0.060 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\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\u003eEnd Type\u003c\/strong\u003e: Single End, Square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: S638\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 pounds\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: 03007642\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558130581810,"sku":"03007642","price":95.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c9e60b8dd76ed78d0de80234cc8705d8_b97fcbc4-6ec8-4f47-a03d-87834de38338.jpg?v=1786404261","url":"https:\/\/voomisupply.com\/products\/seco-03007642-square-end-mill-3-8-in-6-flute-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
