Built from M42 cobalt high-speed steel, it delivers heat resistance and edge retention when cutting steel, stainless steel, cast iron, aluminum and other non-ferrous materials, and high-temperature alloys. The 0.75 inch diameter cutter runs a 3 inch length of cut and a 5.25 inch overall length, making it a long-series tool suited for deeper pockets and extended-reach work. A 30-degree helix spiral flute geometry promotes chip evacuation and smooth cutting action across a wide range of workpiece materials.\u003c\/p\u003e\u003cp\u003eThis end mill fits general-purpose milling operations in job shop and production environments. The SPC408 long series designation means it is built for applications where standard-length tools cannot reach the full depth of cut. It is well suited for milling steel and stainless steel components, cast iron housings, aluminum fixtures, and high-temp alloy parts on manual mills and CNC machining centers. The bright uncoated finish makes it a practical choice when re-sharpening is part of the tool maintenance program.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction provides superior heat and wear resistance compared to standard HSS\u003c\/li\u003e\n\u003cli\u003e4-flute geometry balances material removal rate with chip clearance for ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eLong series SPC408 with 3 inch length of cut for deep pocket and extended-reach milling\u003c\/li\u003e\n\u003cli\u003e30-degree helix spiral flute promotes smooth cutting and efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge milling capability\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute, single end configuration\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish simplifies re-sharpening and supports use across multiple material types\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose long-series square end mill compatible with standard 0.75 inch tool holders, collet chucks, and end mill adapters on manual mills and CNC machining centers.

Secure the 0.75 inch shank in a properly sized collet or end mill holder and verify runout does not exceed 0.001 inches TIR before cutting. Power down and lock out the machine spindle before changing or setting the tool. Follow the machine manufacturer feed, speed, and depth-of-cut recommendations for cobalt tooling on the intended workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SPC408\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0010 \/ -0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.0620 \/ 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR Maximum\u003c\/strong\u003e: 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\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: 17011789\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559466762546,"sku":"17011789","price":106.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/45e003f1f7c442eaf4a97369cd791473_20b49b9d-d8b9-499e-b45f-7bc69e08d4d3.jpg?v=1786433271","url":"https:\/\/voomisupply.com\/products\/seco-17011789-square-end-mill-0-75in-4-flute-cobalt-spc408","provider":"Voomi Supply","version":"1.0","type":"link"}
