With a 3\/4-inch mill diameter, six flutes, and a 2.25-inch length of cut, it delivers material removal rates suited to aggressive toolpaths. The AlTiN+ coating provides thermal resistance and wear protection, making this tool well-suited for cutting high-temperature alloys (ISO workpiece material code S). Variable helix and variable index geometry reduce harmonic chatter and improve surface finish at elevated feed rates. Centercutting capability allows plunge entry. Installed by CNC machinists and toolroom operators in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for milling high-temp alloys such as nickel-based superalloys, titanium, and cobalt-chrome. It fits standard 3\/4-inch collet chucks, hydraulic toolholders, and shrink-fit holders with a 3\/4-inch bore. The 5-inch overall length suits standard vertical machining center spindles with adequate Z-axis clearance. This is a right-hand cutting, right-hand flute tool from the ACCUPRO HS series, appropriate for finish and semi-finish milling passes where edge integrity and thermal stability are critical.\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 workpiece materials\u003c\/li\u003e\n\u003cli\u003eAlTiN+ coating provides high-temperature oxidation resistance suited to dry or minimal-lubricant cutting of superalloys\u003c\/li\u003e\n\u003cli\u003eVariable helix and variable index design reduces chatter and improves surface finish\u003c\/li\u003e\n\u003cli\u003eSix-flute configuration supports higher feed rates and improved chip load per tooth\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003e0.12-inch corner radius (3.05 mm) reduces stress concentration at the cutting edge and improves corner life\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in 3\/4-inch bore toolholders including collet chucks, hydraulic holders, and shrink-fit systems on CNC vertical or horizontal machining centers.

Confirm toolholder bore cleanliness and proper runout before tightening. Follow the toolholder manufacturer's torque specifications for set screws or clamping nuts. Do not exceed the tool manufacturer's recommended cutting data for the target workpiece material and machine spindle power rating.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2.25 inches (57.15 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches (127 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\u003eCorner Radius\u003c\/strong\u003e: 0.12 inches (3.05 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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\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\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\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: 0.96 pounds\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: 72029762\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732123975986,"sku":"72029762","price":423.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_8f5b779b-460a-4e14-af62-f24e0f979b69.jpg?v=1788739466","url":"https:\/\/voomisupply.com\/products\/accupro-72029762-corner-radius-end-mill-3-4-in-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
