It features a 0.315-inch (8.00 mm) cutting diameter with a 0.7874-inch (20.00 mm) length of cut, supported by 2 spiral flutes at a 40-degree helix angle. The TiCN coating improves surface hardness and wear resistance, extending tool life in demanding cutting environments. Constructed from micrograin solid carbide, this end mill delivers consistent performance in ferrous and non-ferrous materials. The centercutting design allows plunge cutting as well as conventional peripheral milling. Right-hand cut and right-hand flute geometry are standard for conventional CNC and manual mill setups.\u003c\/p\u003e\u003cp\u003eThis end mill suits professional machinists and tool-and-die shops running CNC machining centers, knee mills, or manual vertical mills. The regular-length body and 8.00 mm shank diameter make it a practical choice for general-purpose profiling, slotting, and contouring cuts where a compact, rigid tool is preferred. The 40-degree helix promotes efficient chip evacuation, reducing heat buildup during continuous passes in steel, aluminum, and similar workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.315-inch (8.00 mm) cutting diameter with tight mill diameter tolerance of +0.000 \/ -0.002 inches\u003c\/li\u003e\n\u003cli\u003e2 spiral flutes at 40-degree helix angle for improved chip evacuation\u003c\/li\u003e\n\u003cli\u003eTiCN coating for enhanced wear resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eCentercutting design supports both plunge and peripheral milling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute geometry compatible with standard CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose solid carbide square end mill suitable for use in standard CNC machining centers and manual vertical mills accepting an 8.00 mm shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes must be performed by a qualified machinist with the spindle fully stopped and machine power isolated. Use a calibrated tool holder and torque the collet or set screw to the machine manufacturer's specification. Verify runout with a dial indicator before cutting to confirm the shank is seated within tolerance. Follow applicable shop safety standards and machine manufacturer guidelines for speeds and feeds when commissioning a new tool.\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: 2.480 inches (63.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\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\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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\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: 12181390\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51744121553202,"sku":"12181390","price":69.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/77f5407da16b4f381ac06a1f1ff3fde5.jpg?v=1788854437","url":"https:\/\/voomisupply.com\/products\/accupro-12181390-square-end-mill-0-315-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
