Built from micrograin carbide stock, it carries a TiCN (Titanium Carbonitride) coating that increases surface hardness and reduces friction during cutting. The 4-flute, right-hand spiral configuration with a 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. At 0.315 inches in diameter with a 0.7874-inch length of cut, this tool is sized for finish milling, slotting, and profiling work on ferrous and non-ferrous materials. It is centercutting, allowing plunge cuts without a pre-drilled pilot hole.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use in CNC machining centers and manual mills in job shop, production, and toolroom environments. The regular-length geometry makes it a standard choice for general-purpose side milling, contouring, and shallow pocket work where rigidity and precision tolerances are the priority. Machinists and CNC operators working with steel, stainless steel, cast iron, and similar materials will find the TiCN finish and micrograin substrate well matched to those cuts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiCN coating for increased hardness and reduced tool wear\u003c\/li\u003e\n\u003cli\u003e4-flute right-hand spiral design with 40-degree helix angle for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry enables direct plunge entry without a pilot hole\u003c\/li\u003e\n\u003cli\u003eMatched shank and mill diameter at 0.315 inches for straightforward collet setup\u003c\/li\u003e\n\u003cli\u003eRight-hand flute direction compatible with standard CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard single-end square end mill for use in CNC machining centers and manual milling machines accepting 0.315-inch (8 mm) collet or end mill holders.\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 clean, properly sized collet or end mill holder and torque the drawbar or clamping mechanism per the machine tool manufacturer specifications. Verify runout with a dial indicator before commencing a cut. Inspect the cutting edges for chips or damage before each use and replace the tool if the TiCN coating shows significant wear or the flutes are compromised.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.315 inches (8.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.7874 inches (20.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 63.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.315 inches (8.00 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\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\u003eCoating\u003c\/strong\u003e: TiCN\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\u003eExtended Reach\u003c\/strong\u003e: No\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\u003eLength Type\u003c\/strong\u003e: Regular\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\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: 12182515\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51742717149490,"sku":"12182515","price":65.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f910ef7ed6fa585ce7b66b3235f19dc5.jpg?v=1788839034","url":"https:\/\/voomisupply.com\/products\/accupro-12182515-square-end-mill-0-315-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
