With a 3\/4-inch cutting diameter, 5-flute spiral geometry, and a 38-degree helix angle, this tool delivers efficient chip evacuation and a superior surface finish. The AlTiCrN coating provides thermal resistance and extended tool life when cutting hardened steels, stainless alloys, and other abrasive materials. At 6 inches overall length with a 3-1\/4-inch length of cut, it handles deep-pocket and side-milling operations that shorter tools cannot reach. It is installed by CNC machinists and toolroom professionals working on vertical and horizontal machining centers.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits general and high-speed milling operations in job shop, aerospace, and precision manufacturing environments. The single-end, right-hand cutting configuration makes it compatible with standard ER and side-lock toolholders accepting a 3\/4-inch shank. The variable index geometry helps reduce harmonic chatter during aggressive cuts, making it well suited for both roughing and semi-finishing passes in ferrous and non-ferrous materials. The centercutting design also allows plunge entry when required by the machining program.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide micrograin substrate for rigidity and wear resistance at elevated cutting speeds\u003c\/li\u003e\n  \u003cli\u003eAlTiCrN coating extends tool life in high-heat, high-speed applications involving hardened and stainless materials\u003c\/li\u003e\n  \u003cli\u003e5-flute spiral geometry with 38-degree helix angle for efficient chip evacuation and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eVariable index flute spacing reduces chatter and vibration during aggressive roughing passes\u003c\/li\u003e\n  \u003cli\u003eCentercutting design permits plunge milling without a pre-drilled entry hole\u003c\/li\u003e\n  \u003cli\u003e3-1\/4-inch length of cut enables deep-cavity and side-wall milling in a single setup\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard-production cutting tool for CNC machining centers and manual milling machines accepting a 3\/4-inch straight shank.

Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the toolholder collet or side-lock holder to the recommended gauge-line depth before torquing the retention hardware. Verify runout with a dial indicator after assembly and before initiating any cutting program to avoid premature tool wear or workpiece damage.\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 inches (0.7500 inches \/ 19.05 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3-1\/4 inches (3.2500 inches \/ 82.55 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 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\u003c\/strong\u003e: AlTiCrN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\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\u003eSeries\u003c\/strong\u003e: HS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 311833\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51749728452914,"sku":"311833","price":398.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5444340eb392d0b9219bd2b0d894eb91.jpg?v=1788909658","url":"https:\/\/voomisupply.com\/products\/accupro-311833-square-end-mill-3-4-in-5-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
