Built to the HS series specification, it carries an AlTiN+ coating that extends tool life when cutting high-temperature alloys and other abrasive workpiece materials. The 0.75 inch diameter, 6-flute geometry with variable helix and variable index design reduces chatter and improves surface finish at aggressive feed rates. With a 0.09 inch corner radius, this tool blends strength at the cutting edge with smooth transitions on milled profiles. It is a single-end, right-hand cut, centercutting tool — suited for plunge entries and full-slot or peripheral milling operations performed by machinists and tool-and-die professionals.\u003c\/p\u003e\n\u003cp\u003eThis end mill is targeted at shops machining high-temperature alloys (UNSPSC material code S), including nickel-based superalloys, titanium, and similar aerospace and power-generation materials. The AlTiN+ coating and variable helix geometry are well-matched to the heat and tool pressure generated in these applications. With a 2.75 inch length of cut and a 5 inch overall length on a 0.75 inch straight shank, the tool fits standard 3\/4 inch collets and end mill holders on vertical machining centers and CNC mills used in production and job-shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlTiN+ coating for extended tool life in high-temperature alloy and abrasive material applications\u003c\/li\u003e\n  \u003cli\u003eVariable helix and variable index geometry reduces harmonic vibration and improves surface finish\u003c\/li\u003e\n  \u003cli\u003e6-flute design increases feed-per-tooth capacity and productivity compared to lower-flute-count tools\u003c\/li\u003e\n  \u003cli\u003e0.09 inch corner radius protects the cutting edge and produces a controlled radius at part transitions\u003c\/li\u003e\n  \u003cli\u003eCentercutting construction enables direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eSolid carbide substrate delivers rigidity and heat resistance required for difficult-to-machine alloys\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in 3\/4 inch collet chucks, hydraulic holders, or shrink-fit end mill holders on CNC vertical and horizontal machining centers. Primary workpiece material classification is high-temperature alloy (code S).

Seat the 0.75 inch shank fully into the holder to the recommended gauge-line depth before torquing the retention mechanism. Verify runout at the tool tip with a dial indicator before first cut — excessive runout accelerates edge wear on carbide tools. Follow the tool manufacturer and machine builder recommendations for speeds, feeds, and coolant strategy when cutting high-temperature alloys.\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\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2.75 inches (69.85 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: 0.09 inches (2.28 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\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\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\u003eSingle or Double End\u003c\/strong\u003e: Single\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\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\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: 72100449\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730410930482,"sku":"72100449","price":378.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_6a08a0d6-5620-44cb-9ae0-b3a00817a940.jpg?v=1788716993","url":"https:\/\/voomisupply.com\/products\/accupro-72100449-corner-radius-end-mill-3-4-in-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
