It features a 9\/32 inch (0.2812 inch) cutting diameter, a 1-1\/4 inch length of cut, and a 5\/16 inch shank diameter, with an overall length of 3 inches. The micrograin carbide substrate provides hardness and edge retention, while the TiCN coating adds surface hardness and lubricity to reduce heat buildup at the cutting edge. The 40-degree helix angle promotes efficient chip evacuation during cutting. Classified as an extra-long length type, this end mill suits setups requiring additional reach into deep pockets or stepped features.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for machining operations where tight tolerances and clean finishes are required. It is centercutting, allowing direct plunge entry into the workpiece. Right-hand cut and right-hand spiral flute geometry make it compatible with standard CNC machining centers and manual mills running conventional spindle rotation. Machinists working on tool and die, mold making, aerospace components, and general metalworking will find the four-flute configuration appropriate for finishing passes and light-to-moderate roughing in harder materials. The spiral flute design supports continuous chip flow away from the cutting zone.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for high hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces friction and extends tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle improves chip evacuation and cutting efficiency\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge and ramp entry\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand spiral flute for use on standard spindle-direction equipment\u003c\/li\u003e\n  \u003cli\u003eExtra-long length type provides reach for deeper pocket and step milling applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide square end mill compatible with standard ER collet systems, end mill holders, and shrink-fit toolholders accepting a 5\/16 inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the holder to the minimum engagement depth recommended by the toolholder manufacturer. Verify runout with a dial indicator after clamping, as excessive runout will reduce tool life and surface finish quality. Do not exceed the tool manufacturer recommended speeds and feeds for the workpiece material and depth of cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 9\/32 inch (0.2812 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/4 inches (1.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 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: TiCN\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: Extra 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\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: 12183406\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51729181802802,"sku":"12183406","price":72.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ed29b40706015d0480d1a21b40dea443.jpg?v=1788701545","url":"https:\/\/voomisupply.com\/products\/accupro-12183406-square-end-mill-9-32-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
