With a 5\/8 inch (0.6250 inch) mill diameter, 7\/8 inch (0.8750 inch) length of cut, and 3 inch overall length, this stub-length tool delivers rigidity and reduced deflection in tight setups. The micrograin carbide substrate supports higher cutting speeds and feeds compared to standard carbide grades. The AlTiN coating provides thermal resistance and extended tool life in ferrous and hardened material applications. Four spiral flutes with a 40-degree helix angle promote efficient chip evacuation and smooth surface finishes. Licensed machinists, CNC operators, and tool-and-die professionals are the primary users of this end mill.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for slot milling, peripheral milling, and plunge cutting operations in ferrous metals, stainless steels, and high-temperature alloys. The centercutting geometry allows direct plunge entry without pre-drilling. The stub-length body is well-matched to setups requiring maximum tool rigidity, such as shallow-pocket roughing and finishing passes on rigid CNC machining centers or manual mills. The right-hand cut and right-hand flute configuration is standard for conventional CNC spindle rotation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for high hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlTiN finish for thermal protection and extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle with spiral flutes for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without a pilot hole\u003c\/li\u003e\n\u003cli\u003eStub-length body (3 inch OAL) maximizes rigidity and reduces deflection\u003c\/li\u003e\n\u003cli\u003eMill diameter tolerance of +0.000 \/ -0.002 inches for accurate sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling addition for CNC machining centers and manual mills accepting a 5\/8 inch straight shank with a shank diameter tolerance of -0.0001 \/ -0.0004 inches.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Secure the shank in a properly sized collet or end mill holder, ensuring full engagement depth per the holder manufacturer's specification. Verify spindle speed and feed rate against published cutting data for the target material before starting the cut. Do not exceed the length of cut when engaging workpiece material, as cutting beyond the fluted section risks tool breakage and workpiece damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 7\/8 inch (0.8750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 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\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 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\u003eLength Type\u003c\/strong\u003e: Stub\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\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: 12182960\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51743913148722,"sku":"12182960","price":108.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1ce65bc97b5e6ff0e0d1e088dea59696.jpg?v=1788851180","url":"https:\/\/voomisupply.com\/products\/accupro-12182960-square-end-mill-5-8-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
