This two-flute, single-end tool features a 7\/16 inch cutting diameter with a 1 inch length of cut and a 4 inch overall length, classifying it in the long-length category. The 40-degree helix angle and TiCN coating improve chip evacuation and resist heat buildup, making this end mill suitable for higher-feed passes in ferrous and non-ferrous materials. Micrograin carbide construction provides edge retention and rigidity at the cutting zone. Machinists and toolroom operators working in manual or CNC setups are the primary installers of this tool.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for slotting, profiling, and plunge-capable operations in ferrous metals, aluminum, and similar materials where a long-reach, two-flute geometry is appropriate. The centercutting configuration allows direct plunge entry without a pilot hole, expanding its use in pocketing operations. Its long-length classification makes it useful when additional reach is needed to clear part geometry or fixturing in both vertical and horizontal milling setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/16 inch (0.4375 inch) cutting diameter with mill diameter tolerance of +0.000 \/ -0.002 inches\u003c\/li\u003e\n  \u003cli\u003eTiCN finish for improved wear resistance and reduced built-up edge in metal cutting\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle with spiral flute geometry for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting design supports direct plunge entry into material\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for edge stability in demanding cuts\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute configuration — standard orientation for most milling spindles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style tooling solution for use in standard 7\/16 inch collets or end mill holders on CNC machining centers and manual knee mills requiring a long-length, two-flute square end mill.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis end mill is installed by machinists and toolroom professionals using a compatible collet, end mill holder, or shrink-fit toolholder sized for a 7\/16 inch shank. Confirm the holder is clean and free of debris before seating the tool, and torque retention hardware per the toolholder manufacturer specifications. Shank diameter tolerance is -0.0001 \/ -0.0004 inches, so verify holder fit before use. Always power down and lock out the spindle before changing tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 7\/16 inch (0.4375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7\/16 inch (0.4375 inches)\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, Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\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: Long\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: 0.3 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: 12181819\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738529136946,"sku":"12181819","price":102.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b146b26891ac9ee702aff5c486a2b2f4_2d5546d5-c405-4c74-9cd9-6ed5710015f7.jpg?v=1788800651","url":"https:\/\/voomisupply.com\/products\/accupro-12181819-square-end-mill-7-16-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
