Built from M42 cobalt high-speed steel, it delivers heat resistance and edge retention that standard HSS tooling cannot match. The cutter measures 1 inch in diameter with a 6 inch length of cut, a 1 inch shank diameter, and an 8.5 inch overall length. Four right-hand spiral flutes with a 30-degree helix angle provide efficient chip evacuation and smooth cutting action. The bright uncoated finish makes it well suited for applications where coatings are not required or where regrinding is anticipated. Centercutting geometry allows for plunge entry directly into the workpiece.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling operations on steel, stainless steel, cast iron, aluminum and non-ferrous metals, and high-temperature alloys. The regular-length profile and 1 inch shank make it compatible with standard end mill holders and collet chucks found on vertical machining centers, knee mills, and CNC milling machines across job shop and production environments. It belongs to SECO Series SPC408 and is sized for heavier roughing and finishing passes where a full-inch cutter is appropriate.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction for improved heat and wear resistance over standard HSS\u003c\/li\u003e\n\u003cli\u003e4 right-hand spiral flutes with 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge milling without a pre-drilled entry hole\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for regrinding and dry or lubricated cutting\u003c\/li\u003e\n\u003cli\u003e1 inch shank diameter fits standard end mill holders and collet chucks\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute geometry for conventional milling machine spindles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 1 inch end mill holders, side-lock holders, and collet chucks on vertical machining centers and manual knee mills.

Ensure the spindle is fully stopped and the machine is in an e-stop or locked-out state before changing tooling. Secure the shank to the full recommended gauge-line depth in the holder to maintain rigidity and minimize runout. Verify TIR at the tool tip after installation before running the first cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8.5 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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\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\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\u003eSeries\u003c\/strong\u003e: SPC408\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 17011831\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51562858938674,"sku":"17011831","price":223.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/45e003f1f7c442eaf4a97369cd791473_8feb4c58-cde2-4ab9-ad6b-ad9eefc73949.jpg?v=1786485989","url":"https:\/\/voomisupply.com\/products\/seco-17011831-square-end-mill-1in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
