The tool measures 0.75 inches in diameter with a 3.25-inch length of cut and a 0.03-inch corner radius, making it well suited for finishing and semi-finishing passes where edge integrity matters. The AlTiN+ coating provides elevated heat resistance and hardness, extending tool life in abrasive and high-temperature workpiece materials. Six flutes with variable helix and variable index geometry reduce harmonic vibration and chatter during deep-cavity cuts. This is a right-hand cut, right-hand flute, single-end tool intended for professional CNC machining environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is designed primarily for milling high-temperature alloys (ANSI material code S), including nickel-based superalloys, titanium, and similar hard-to-machine materials common in aerospace, power generation, and advanced manufacturing work. The centercutting design allows plunge entry, adding versatility on 3-axis and 5-axis CNC machining centers. With a 0.75-inch shank diameter matching the cutting diameter, the tool seats securely in standard ER or side-lock holders. The 6-inch overall length provides reach for deeper pockets without requiring extended-reach toolholders in most setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN+ coating rated for elevated cutting temperatures in high-temp alloys\u003c\/li\u003e\n  \u003cli\u003eVariable helix and variable index flute geometry reduces chatter and vibration\u003c\/li\u003e\n  \u003cli\u003e0.03-inch corner radius protects the cutting edge and improves surface finish at part corners\u003c\/li\u003e\n  \u003cli\u003eCentercutting capable — supports plunge milling operations\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute, single end configuration\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers with 3\/4-inch toolholding systems.

Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the holder to the recommended gauge-line depth and torque the retention mechanism per the toolholder manufacturer specification. Verify runout with a dial indicator before beginning a production cut, particularly given the close corner radius tolerance on this tool.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.75 inches (19.05 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches (19.05 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3.25 inches (82.55 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches (152.4 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.03 inches (0.76 mm)\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\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: Variable\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: High-Temp Alloy (Code S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.21 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 72021777\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732144881970,"sku":"72021777","price":460.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_0e9e3299-1d54-4384-a98f-492d7f668dfc.jpg?v=1788739707","url":"https:\/\/voomisupply.com\/products\/accupro-72021777-corner-radius-end-mill-3-4-in-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
