With a 0.3543-inch (9 mm) mill diameter, a 0.5512-inch length of cut, and a 2-3\/4-inch overall length, this stub-length tool offers rigidity and reduced deflection in tight-clearance applications. The 4-flute, 40-degree helix spiral flute geometry promotes efficient chip evacuation and smooth cutting action. Centercutting capability allows plunge entry directly into the workpiece. The uncoated micrograin carbide construction provides wear resistance and edge retention across a range of materials. Machinists and toolroom operators working on CNC mills or manual knee mills are the primary users of this end mill.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits general-purpose peripheral milling, slotting, and profiling in ferrous and non-ferrous materials. The stub length type keeps overhang minimal, making it well suited for face milling, shallow pocket work, and finishing passes where chatter control matters. Right-hand cut and right-hand flute configuration match standard spindle rotation on conventional machining centers. The 10 mm shank diameter fits standard ER and side-lock toolholders common in production and job-shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.3543-inch (9 mm) mill diameter with a tight tolerance of +0.000 \/ -0.002 inches for dimensional accuracy\u003c\/li\u003e\n  \u003cli\u003e4-flute spiral flute design with 40-degree helix angle for efficient chip flow and surface finish quality\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge milling without a pre-drilled entry hole\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide construction delivers edge sharpness and wear resistance\u003c\/li\u003e\n  \u003cli\u003eStub length (0.5512-inch LOC) minimizes deflection and maximizes rigidity in short-reach applications\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suited for non-ferrous metals, plastics, and general toolroom use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard toolroom end mill compatible with CNC machining centers and manual mills accepting a 10 mm shank diameter via ER collet chucks, milling chucks, or side-lock holders.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians following standard toolholding procedures. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill from the holder. Verify shank seating depth and runout with a dial indicator before commencing cuts. Observe the shank diameter tolerance of -0.0001 \/ -0.0004 inches when selecting collet size to ensure proper grip and minimize runout.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.3543 inches (9 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5512 inches (14 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/4 inches (70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 10 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\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\u003eCoating\u003c\/strong\u003e: Uncoated\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: 0.12 pounds\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: 12182868\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51749211472178,"sku":"12182868","price":77.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/963c08da0fee16aad61a7039f9ab40e1.jpg?v=1788903193","url":"https:\/\/voomisupply.com\/products\/accupro-12182868-square-end-mill-0-3543-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
