Ground from micrograin solid carbide, it delivers rigidity and wear resistance that high-speed steel tooling cannot match. The 0.5 inch diameter cutting head carries four right-hand spiral flutes with a 40-degree helix angle, promoting efficient chip evacuation and reducing cutting forces. An nACRo physical vapor deposition coating provides thermal resistance and lubricity, extending tool life in dry or minimal-lubrication machining environments. Machinists and CNC operators in job shops, aerospace fabrication, and general manufacturing use this tool for finish and semi-finish passes.\u003c\/p\u003e\u003cp\u003eThis end mill suits CNC machining center applications requiring a 0.5 inch diameter ball nose profile with a 1 inch length of cut and a 4 inch overall length. The 0.5 inch shank diameter fits standard ER, Weldon, and shrink-fit toolholders commonly found in vertical and horizontal machining centers. The right-hand cutting direction and spiral flute geometry make it appropriate for conventional and climb milling of steel, stainless steel, cast iron, and similar materials where the nACRo coating provides a performance advantage over uncoated or TiN-coated alternatives.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for superior hardness and edge retention\u003c\/li\u003e\n\u003cli\u003enACRo coating provides high-temperature resistance and reduced friction in cutting applications\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes smooth chip flow and reduces heat buildup at the cutting edge\u003c\/li\u003e\n\u003cli\u003eFour flutes deliver a balance of chip clearance and surface finish quality\u003c\/li\u003e\n\u003cli\u003eSingle-end ball nose geometry suited for contouring, profiling, and 3D surface milling\u003c\/li\u003e\n\u003cli\u003eMill diameter tolerance of +0.000 to -0.002 inches ensures dimensional accuracy on finished passes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills accepting a 0.5 inch shank diameter with ER, Weldon, or shrink-fit toolholding systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the control is in an e-stop or locked-out state before inserting or removing tooling. Clean the toolholder bore and shank before assembly to prevent runout caused by chips or contamination. Confirm tool projection and reach requirements in the CAM program before beginning a cutting cycle to avoid toolholder interference with the workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: nACRo\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\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 to -0.002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 12179302\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51748249207090,"sku":"12179302","price":166.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ee82fc6eb7f8370f036a4008b5538dc4_2097aef9-a4ca-4818-971a-eba3eac7441c.jpg?v=1788891087","url":"https:\/\/voomisupply.com\/products\/accupro-12179302-ball-end-mill-0-5in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
