It features a 0.75 inch mill diameter, a 1.5 inch length of cut, and a 4 inch overall length, making it well suited for general-purpose profiling, slotting, and peripheral milling operations. The four-flute spiral configuration with a 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. An AlTiN coating provides thermal resistance and extended tool life when cutting hardened steels, stainless alloys, and other demanding materials. The micrograin carbide substrate adds wear resistance at elevated cutting speeds. This tool is installed by machinists and CNC operators in job shop and production environments.\u003c\/p\u003e\u003cp\u003eThis end mill fits standard CNC machining centers, vertical mills, and manual knee mills that accept a 0.75 inch shank. It is appropriate for dry or near-dry cutting of ferrous metals, hardened steels, and cast iron where the AlTiN finish provides heat resistance without coolant. Centercutting capability allows direct plunge entry into the workpiece, adding flexibility for pocket milling and ramping operations in both roughing and finishing passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for high rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for thermal protection in high-speed and dry cutting conditions\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes efficient chip evacuation and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry for pocket and ramp milling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with right-hand spiral flute for compatibility with standard CNC spindle rotation\u003c\/li\u003e\n\u003cli\u003eMill diameter tolerance of +0.001\/-0.000 inches ensures consistent dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or new-install solid carbide square end mill for any machine tool spindle accepting a 0.75 inch straight shank, including standard CNC machining centers and manual vertical mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist or CNC operator. Power down and lock out the machine spindle before inserting or removing the tool from the holder. Seat the shank fully into the collet or end mill holder and torque to the tool holder manufacturer specification. Verify runout with a dial indicator before beginning a cut. Follow applicable shop safety procedures and machine manufacturer guidelines for spindle speed and feed rate selection.\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\u003eLength of Cut\u003c\/strong\u003e: 1.5 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\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.001\/-0.000 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\u003eWeight\u003c\/strong\u003e: 0.835 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: 12177095\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51742177394994,"sku":"12177095","price":316.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e664c4acea0d3b6343c8fbc6cd8c919f.jpg?v=1788835795","url":"https:\/\/voomisupply.com\/products\/accupro-12177095-square-end-mill-3-4-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
