It runs a 1.5-inch cutting diameter with a 4-inch length of cut, delivering the extended reach needed for deep-pocket and slotting work. The 6-flute geometry with a 30-degree right-hand spiral helix provides a balance of chip evacuation and surface finish across a wide range of workpiece materials. The bright uncoated finish is standard for this cobalt grade. Licensed machinists and toolroom operators use this tool in manual and CNC knee mills, vertical machining centers, and similar setups where a large-diameter, long-reach end mill is required.\u003c\/p\u003e\u003cp\u003eThe 17011892 is designed for milling steel, stainless steel, cast iron, aluminum and non-ferrous metals, and high-temperature alloys. Its centercutting design allows direct plunge entry as well as conventional peripheral and slot milling. The 1.25-inch shank diameter seats in standard ER, R8, CAT, or BT toolholders with the appropriate collet or end mill holder. The 6.5-inch overall length suits setups requiring clearance over fixtures or tall workpiece features. This tool falls within the SECO SPC408 long-series end mill family.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction for elevated heat and wear resistance compared to standard HSS\u003c\/li\u003e\n\u003cli\u003e6 flutes with 30-degree right-hand spiral helix for improved finish and feed capability\u003c\/li\u003e\n\u003cli\u003e4-inch length of cut supports deep-pocket and long-reach milling without extended tooling adapters\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows plunge, slot, and peripheral milling in a single tool\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish compatible with cutting fluids and straight-oil coolants across multiple materials\u003c\/li\u003e\n\u003cli\u003eNo chipbreaker or variable helix — suited to conventional and CNC roughing and finishing passes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a long-series OEM-style end mill within the SECO SPC408 series.

Verify toolholder runout before cutting — the TIR maximum for this tool is 0.001 inches. Torque retention screws or collet nuts to the toolholder manufacturer specification. Confirm spindle speed and feed rate are calculated for the 1.5-inch cutting diameter before engaging the workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.5 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: 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\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR Maximum\u003c\/strong\u003e: 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0030 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -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\u003eSeries\u003c\/strong\u003e: SPC408\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 pounds\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: 17011892\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558894600498,"sku":"17011892","price":299.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/45e003f1f7c442eaf4a97369cd791473_852e0f44-8d2e-4fe2-a7ea-55849592952a.jpg?v=1786422054","url":"https:\/\/voomisupply.com\/products\/seco-17011892-square-end-mill-1-1-2-in-6-flute-cobalt-spc408","provider":"Voomi Supply","version":"1.0","type":"link"}
