It features a 3\/8-inch cutting diameter, a 1\/2-inch length of cut, and a 3-flute configuration with a 45-degree right-hand spiral flute geometry. The micrograin carbide construction delivers edge retention and dimensional accuracy in high-speed operations. This is a single-end, centercutting tool, allowing plunge entry in addition to peripheral and slot milling. The bright uncoated finish suits applications where coating interaction with workpiece material is a concern. Licensed machinists and CNC programmers specify this tool for finishing and semi-finishing passes on aluminum, brass, copper, and similar non-ferrous materials.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use in CNC machining centers and manual mills handling aluminum, non-ferrous alloys, and similar low-abrasion materials. The stub-length profile limits overhang and improves rigidity during short-reach operations. The 3\/8-inch straight shank fits standard ER collets and end mill holders common to most vertical machining center setups. Right-hand cut and right-hand flute orientation match conventional milling spindle rotation. The Series A345 designation identifies it within the SECO fractional-inch solid carbide end mill line.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3-flute solid carbide construction with micrograin substrate for edge durability\u003c\/li\u003e\n\u003cli\u003e45-degree right-hand spiral flute promotes efficient chip evacuation in non-ferrous cuts\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows plunge milling without a pilot hole\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish optimized for aluminum and non-ferrous workpiece materials\u003c\/li\u003e\n\u003cli\u003eStub-length body reduces deflection in short-reach applications\u003c\/li\u003e\n\u003cli\u003eStraight shank compatible with standard ER collets and end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with aluminum and non-ferrous materials (Primary Workpiece Material Code: N) as specified in the SECO Series A345 solid carbide end mill line.

Verify collet or toolholder bore size matches the 3\/8-inch shank before clamping. Inspect runout after installation — maximum specified TIR is 0.0005 inches — and re-seat the tool if runout exceeds this value. Do not exceed the tool manufacturer's recommended feed and speed parameters for the target workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches (2.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\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\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\u003eShank Type\u003c\/strong\u003e: Straight\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\u003eLength Type\u003c\/strong\u003e: Stub\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 \/ -0.0020 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.0015 \/ -0.0015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum TIR\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: 0.25 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: 17003151\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51560868380978,"sku":"17003151","price":80.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e39ffcef59c3778b0674908b95ca55de_b3bdcf76-68c1-4468-80fd-32c66449889b.jpg?v=1786458906","url":"https:\/\/voomisupply.com\/products\/seco-17003151-square-end-mill-3-8-inch-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
