It features a 3\/4 inch cutting diameter, a 2-1\/4 inch length of cut, and a 5 inch overall length with a matching 3\/4 inch shank. Seven spiral flutes with a 37.5-degree helix angle and an nACRo finish allow aggressive metal removal rates while resisting built-up edge and heat at the cutting zone. The micrograin carbide substrate provides the hardness and toughness required for demanding cutting conditions in production and job-shop environments. Licensed machinists and CNC programmers running vertical or horizontal machining centers will find this tool well suited to finishing and semi-finishing passes.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling slots, profiles, and pockets on a CNC machining center or manual knee mill where a right-hand cut, right-hand spiral configuration is required. The centercutting geometry allows direct plunge entry, eliminating the need for a pre-drilled start hole in many applications. The extended 2-1\/4 inch length of cut accommodates deeper pocket work without requiring a long-reach variant. The nACRo PVD coating improves performance in alloy steels, stainless steels, and hardened materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003e7 flutes with a 37.5-degree helix angle for efficient chip evacuation and smooth finish\u003c\/li\u003e\n\u003cli\u003enACRo finish coating extends tool life in ferrous and hardened materials\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling without a pilot hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard CNC spindle rotation\u003c\/li\u003e\n\u003cli\u003eMill diameter tolerance of +0.000 \/ -0.002 inches ensures precise fit and accurate cuts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 3\/4 inch shank square end mill compatible with ER, CAT, BT, and straight-collet toolholders used on CNC vertical machining centers and manual knee mills that accept 3\/4 inch shank tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle and toolholder are completely powered down and locked out before loading or changing the end mill. Seat the shank to the minimum recommended engagement depth in the toolholder collet and torque the retention nut per the toolholder manufacturer specifications. Inspect the cutting edges for chips or coating damage before initiating a new program run.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 7\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: nACRo\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2-1\/4 inches (2.2500 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\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 37.5 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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 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\u003eWeight\u003c\/strong\u003e: 1.153 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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12180832\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51731071729970,"sku":"12180832","price":396.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/77041931bec9b6edec5780f3757979ab.jpg?v=1788726597","url":"https:\/\/voomisupply.com\/products\/accupro-12180832-square-end-mill-3-4-in-7-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
