It features a 3\/4 inch cutting diameter, a 4 inch length of cut, and a 45-degree helix angle that promotes efficient chip evacuation in soft and gummy materials. The micrograin carbide substrate provides hardness and edge retention without coatings, keeping the cutting edge sharp on materials where built-up edge is a concern. This is a single-end, centercutting tool, meaning it can plunge as well as peripheral mill. Machinists and CNC operators running aluminum, brass, copper, or similar non-ferrous alloys will find this tool suited to finish and semi-finish passes at aggressive feeds.\u003c\/p\u003e\n\u003cp\u003eThe 17003172 belongs to SECO Series A345 and is configured for right-hand cut with right-hand spiral flutes, a straight shank, and regular length geometry. It fits standard ER collet chucks, end mill holders, or hydraulic toolholders accepting a 3\/4 inch straight shank. The 6.5 inch overall length provides moderate reach for workpieces requiring tool clearance beyond a standard stub-length end mill without sacrificing rigidity. Typical applications include pocket milling, slotting, contouring, and profiling operations on aluminum plate, extrusions, castings, and bar stock in job shop and production CNC environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for superior edge retention on non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003e45-degree helix angle promotes aggressive chip evacuation in aluminum and similar alloys\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish eliminates coating adhesion risk on sticky non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003e3 flutes balance chip clearance and cutting contact for aluminum-optimized performance\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute configuration suits standard CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and manual mills equipped with toolholders accepting a 3\/4 inch straight shank.

Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool from its holder. Seat the shank to the recommended gauge-line depth in the collet or end mill holder and torque the retention system per the toolholder manufacturer specification. Verify tool runout does not exceed the 0.0005 inch TIR maximum before starting the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 4 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\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\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\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum and Non-Ferrous\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0020 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.0600 to -0.0600 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR Maximum\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A345\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.12 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 17003172\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51557412012338,"sku":"17003172","price":693.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e39ffcef59c3778b0674908b95ca55de.jpg?v=1786387568","url":"https:\/\/voomisupply.com\/products\/seco-17003172-square-end-mill-3-4-in-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
