Built from M42 cobalt high-speed steel, it delivers good wear resistance and toughness compared to standard HSS tooling. The cutter features a 0.75-inch diameter, a 2-inch length of cut, and a 0.75-inch straight shank, giving it a total overall length of 4.25 inches. Its 4-flute, spiral-flute geometry with a 30-degree helix angle promotes smooth chip evacuation and consistent surface finish. The bright uncoated finish keeps tooling costs low where coatings are not required. Licensed machinists and CNC programmers use this tool in vertical and horizontal milling operations across job shops and production environments.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for slotting, profiling, and peripheral milling on ferrous and non-ferrous workpiece materials. Rated workpiece material categories include steel, stainless steel, cast iron, aluminum and non-ferrous alloys, and high-temperature alloys. The right-hand cut and right-hand flute configuration is compatible with standard CNC machining centers and manual milling machines. Centercutting capability allows plunge entry into the workpiece without pre-drilling, which adds flexibility to the machining process. The SPC408 series is a general-purpose cobalt offering appropriate for both prototype and production runs where tool life and dimensional accuracy matter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for improved heat and wear resistance over standard HSS\u003c\/li\u003e\n\u003cli\u003e4-flute spiral geometry with 30-degree helix for balanced chip evacuation and finish quality\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for general-purpose milling without coating surcharge\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute — standard configuration for conventional CNC setups\u003c\/li\u003e\n\u003cli\u003eNo chipbreaker, extended reach, or coolant-through features, keeping geometry straightforward for standard applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose replacement or production end mill compatible with standard 0.75-inch collet chucks, end mill holders, and hydraulic toolholders used in CNC machining centers and manual vertical mills.

Ensure the spindle is fully stopped and the machine is in an e-stop or locked-out state before seating or removing the tool from the holder. Verify proper runout (TIR maximum 0.0010 inches) after tool installation using a dial indicator before beginning the cut. Follow shop-standard feeds-and-speeds practice for the target workpiece material and consult the applicable cutting data for cobalt tooling when programming spindle speeds and feed rates.\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: 2 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\u003eOverall Length\u003c\/strong\u003e: 4.25 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 HSS)\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\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: 0.0010 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Aluminum and Non-Ferrous, High-Temp Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SPC408\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 17011788\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51562501046578,"sku":"17011788","price":108.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/45e003f1f7c442eaf4a97369cd791473_5b5804b0-970a-44b3-b9f2-e4cdd574bd05.jpg?v=1786478170","url":"https:\/\/voomisupply.com\/products\/seco-17011788-square-end-mill-0-75in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
