With a 0.5000 inch (1\/2 inch) mill diameter and 6 helical flutes, this single-end tool delivers efficient material removal and superior surface finish in difficult-to-machine workpiece materials. The AlTiN+ coating enhances heat resistance and tool life, making it well-suited for high-temperature alloy machining. A variable helix angle (36 and 40 degrees) combined with variable index geometry reduces chatter and vibration, improving finish quality and dimensional consistency in the cut. The tool features a straight shank at 0.5000 inch diameter, right-hand cutting direction, and centercutting capability for plunge entry.\u003c\/p\u003e\u003cp\u003eThis end mill is designed for professional machinists and CNC operators working with high-temp alloys (Material Code S), including nickel-based, titanium, and cobalt superalloys commonly found in aerospace, medical, and power generation applications. The 2.5000 inch length of cut and 5.0000 inch overall length provide substantial reach for deep-cavity milling, slotting, profiling, and contouring operations. Its centercutting design allows direct plunge milling without a pre-drilled hole.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eAlTiN+ coating for elevated heat resistance and extended tool life in high-temp alloy applications\u003c\/li\u003e\n\u003cli\u003eVariable helix (36 and 40 degrees) and variable index design reduce vibration and chatter\u003c\/li\u003e\n\u003cli\u003e6-flute configuration improves surface finish and feed rate capability\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry enables plunge entry without a starter hole\u003c\/li\u003e\n\u003cli\u003eSingle-end design with right-hand flute and cutting direction for standard CNC spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit solid carbide ball end mill in the ACCUPRO HS Series, optimized for high-temperature alloy (S-class material code) milling on CNC machining centers using 1\/2 inch toolholders.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Secure the straight shank in a compatible 1\/2 inch collet chuck, end mill holder, or hydraulic holder and torque to the toolholder manufacturer specification. Verify runout with a dial indicator before the first cut. Coolant-through is not supported on this tool; external coolant or minimum quantity lubrication (MQL) is recommended for high-temp alloy applications.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5000 inches (1\/2 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN+\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2.5000 inches (2-1\/2 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5000 inches (1\/2 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 36 and 40 degrees (variable)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: High-Temp Alloy (Material Code S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\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: 0.44 pounds\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: 72089659\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51748697375026,"sku":"72089659","price":189.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_c8c8e887-28cc-4769-a0d2-6e7825dc9f22.jpg?v=1788896912","url":"https:\/\/voomisupply.com\/products\/accupro-72089659-ball-end-mill-1-2-in-6-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
