It is ground from micrograin solid carbide for rigidity and edge retention, and carries a ZrN (zirconium nitride) coating that reduces friction and extends tool life in ferrous and non-ferrous materials. The mill measures 1 inch in diameter with a 2 inch length of cut and a 5 inch overall length. The 37-degree helix angle promotes efficient chip evacuation, and the three-flute geometry balances material removal rate with surface finish quality. Installed by machinists and CNC operators on vertical and horizontal machining centers.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for medium to high-speed finishing and semi-finishing passes on molds, dies, and complex contoured parts. The 1 inch shank diameter provides a secure grip in standard ER or side-lock toolholders. The right-hand cut and right-hand spiral flute direction are standard for the majority of CNC milling setups. The ZrN coating makes this tool a practical choice when running aluminum, stainless, alloy steels, and hardened materials where heat and built-up edge are concerns.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for superior hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eZrN coating reduces friction and extends tool life across a range of workpiece materials\u003c\/li\u003e\n\u003cli\u003e37-degree helix angle promotes aggressive chip evacuation and smooth cutting action\u003c\/li\u003e\n\u003cli\u003e3-flute design balances cutting efficiency with finish quality on contoured surfaces\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with right-hand cut and right-hand spiral\u003c\/li\u003e\n\u003cli\u003eMill diameter tolerance of +0.000 \/ -0.002 inches for consistent fit and dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1 inch shank ball end mill compatible with ER collet chucks, side-lock holders, and shrink-fit toolholders sized for 1 inch straight shanks on CNC vertical and horizontal machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Always power down and lock out the spindle before changing tooling. Ensure the shank is fully seated to the recommended gauge line in the toolholder and that holder runout is verified before cutting. Consult the machine tool manufacturer specifications and applicable shop safety procedures when setting speeds and feeds for carbide tooling.\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: 2 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 (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\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 315346\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51729847812402,"sku":"315346","price":659.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c2200e7e1b0c193f966a4890e2cbce31.jpg?v=1788709553","url":"https:\/\/voomisupply.com\/products\/accupro-315346-ball-end-mill-1-in-3-flute-solid-carbide-zrn","provider":"Voomi Supply","version":"1.0","type":"link"}
