Built from micrograin solid carbide, it delivers the rigidity and edge retention required for demanding contouring, profiling, and 3D surfacing work. The 1 inch diameter cutting head has a 1-1\/4 inch length of cut and a 37-degree helix angle that promotes efficient chip evacuation and smooth cutting action. A zirconium nitride (ZrN) coating adds surface hardness and heat resistance, extending tool life in abrasive materials. This end mill is a standard tool for machinists and tool-and-die professionals working on CNC mills and machining centers.\u003c\/p\u003e\u003cp\u003eThe 315340 is suited for profiling, slotting, and contouring applications in shop environments running CNC vertical or horizontal machining centers. Its 1 inch shank diameter fits standard toolholders used in production and job-shop settings. The right-hand cutting and right-hand spiral flute direction make it compatible with conventional milling setups. With a 5 inch overall length, it provides adequate reach for most standard workpiece geometries without introducing excess overhang.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for high rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eZrN coating improves hardness and reduces heat buildup at the cutting edge\u003c\/li\u003e\n\u003cli\u003e37-degree helix angle promotes chip flow and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003e3-flute design balances chip clearance with cutting edge strength\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand spiral flute direction for standard CNC setups\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with consistent mill diameter tolerance of +0.000 \/ -0.002 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tooling option for CNC machining centers and vertical mills accepting a 1 inch shank diameter in standard toolholders.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the end mill from the toolholder. Use the appropriate collet or end mill holder rated for a 1 inch shank and torque the retention fastener to the toolholder manufacturer specification. Verify runout with a dial indicator before beginning a cut to avoid premature edge wear or tool failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 37 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\/Finish\u003c\/strong\u003e: ZrN (Zirconium Nitride)\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\u003eSingle or Double End\u003c\/strong\u003e: Single\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\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\u003eWeight\u003c\/strong\u003e: 1 pound\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: 315340\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51753402990898,"sku":"315340","price":684.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4855a23de2ead4a84ef540027b5c7195.jpg?v=1788936369","url":"https:\/\/voomisupply.com\/products\/accupro-315340-ball-end-mill-1-in-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
