Built with 6 flutes and a 40-degree helix angle, this centercutting tool delivers efficient chip evacuation and smooth surface finishes in a wide range of profiling, slotting, and peripheral milling applications. The micrograin carbide construction provides hardness and wear resistance suited to demanding production environments. With a 3\/8 inch mill diameter and a 1-1\/8 inch length of cut, it fits standard toolholding systems and is well-suited for both CNC machining centers and manual milling machines. Machinists and tool-and-die professionals select this geometry for its balance of rigidity and reach.\u003c\/p\u003e\n\u003cp\u003eThis end mill is classified as a long-length tool with a 3-inch overall length, making it appropriate for applications requiring extended reach into pockets, slots, or stepped features. The bright uncoated finish makes it a practical choice for aluminum, brass, copper, plastics, and other non-ferrous materials where coatings are unnecessary or undesirable. Right-hand cutting and right-hand flute direction are standard for conventional CNC spindle setups. It is sold individually and packaged as a single unit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e6-flute geometry with 40-degree helix angle for improved surface finish and chip flow\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge entry directly into workpiece material\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide construction for hardness and extended tool life\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suited to non-ferrous and non-metallic workpiece materials\u003c\/li\u003e\n  \u003cli\u003eLong-length classification with 3-inch overall length for extended reach applications\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand spiral for use with standard CNC and manual milling spindles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or standard tooling selection for 3\/8 inch diameter collet chucks, end mill holders, and shrink-fit toolholders used in CNC machining centers and conventional vertical milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and tool changes should be performed with the machine spindle fully stopped and the control placed in a safe, locked-out state per applicable shop safety procedures. Ensure the shank is clean and fully seated in the toolholder before tightening. Verify runout with a dial indicator after clamping, particularly for tight-tolerance finishing operations. Follow machine manufacturer and tooling supplier guidelines for speeds and feeds appropriate to the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/8 inches (1.1250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\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: Bright \/ Uncoated\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 Spiral\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\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: 12183878\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730925453618,"sku":"12183878","price":76.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/230c1ceb983d0d0bdffaecbc402c66e0.jpg?v=1788724889","url":"https:\/\/voomisupply.com\/products\/accupro-12183878-square-end-mill-3-8-in-6-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
