Built from solid carbide with an M42 material grade designation, this tool features 3 spiral flutes with a coarse pitch geometry and a 30-degree maximum helix angle. The 45-degree chamfer angle aids in entry cuts and edge breaking. At 0.75 inches in diameter with a 1.625-inch length of cut and 4-inch overall length, it is sized for standard vertical and horizontal milling setups. A bright, uncoated finish means it ships ready to use without additional surface treatment. This cutter is installed by machinists and toolroom technicians working in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis roughing end mill is suited for high-speed stock removal passes in ferrous and non-ferrous materials where surface finish is secondary to material removal rate. The coarse pitch flute design breaks chips aggressively, reducing heat buildup and re-cutting of chips during deep passes. The straight-cylindrical shank at 0.75 inches diameter fits standard ER and side-lock collet systems. It is a right-hand cut, right-hand flute configuration. Centercutting capability allows plunge entry without a pre-drilled pilot hole, supporting ramping and helical interpolation strategies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction, M42 material grade, for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003e3 spiral flutes, coarse pitch, right-hand cut and right-hand flute direction\u003c\/li\u003e\n\u003cli\u003eCentercutting design supports plunge, ramp, and helical entry\u003c\/li\u003e\n\u003cli\u003e30-degree maximum helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003e45-degree chamfer angle at 0.025 inches chamfer width for edge transition cuts\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish — no coating removal required before use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use roughing end mill compatible with standard straight-cylindrical collet and side-lock toolholders accepting a 0.75-inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Secure the shank fully within the toolholder to the minimum insertion depth recommended by the toolholder manufacturer, and verify runout before cutting. Confirm spindle speed and feed rate are set per the material and depth-of-cut requirements before engaging the workpiece. Inspect the cutting edges for chips or damage before each use — carbide end mills should not be used if edge integrity is compromised.\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\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42\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\u003eHelix Angle (Maximum)\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Width\u003c\/strong\u003e: 0.025 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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: 0.060 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: AR330\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.72 pounds\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: 17004691\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558062555442,"sku":"17004691","price":355.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3a94a226cf10e7eae2ccd6fa9dd0b4a2.jpg?v=1786402301","url":"https:\/\/voomisupply.com\/products\/seco-17004691-roughing-end-mill-3-4-in-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
