Built from micrograin solid carbide and coated with AlTiN (aluminum titanium nitride), it delivers hardness and heat resistance needed for cutting ferrous and hardened materials. The tool features a 3\/4-inch mill diameter, a 1-5\/8-inch length of cut (1.875 inches actual), and a 0.03-inch corner radius that reduces edge chipping and extends tool life in interrupted cuts. With a 35-degree helix angle and three right-hand flutes, it provides efficient chip evacuation and a smooth finish in roughing and semi-finishing passes.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for vertical machining centers, CNC mills, and manual knee mills running ferrous alloys, stainless steel, titanium, and hardened steels. The centercutting geometry allows for plunge entry, giving machinists flexibility in toolpath programming. It is a standard-reach, regular-length tool appropriate for production shops, tool rooms, and job shops where corner radius geometry is specified to reduce stress concentrations on finished workpiece edges.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating provides high-temperature hardness and oxidation resistance\u003c\/li\u003e\n  \u003cli\u003e0.03-inch corner radius reduces edge breakout and extends tool life\u003c\/li\u003e\n  \u003cli\u003e35-degree helix angle promotes efficient chip evacuation and smooth cutting action\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry into workpiece\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute spiral for standard CNC spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 3\/4-inch shank corner radius end mill compatible with ER, CAT, BT, and HSK toolholders accepting a 3\/4-inch straight shank.

Ensure the toolholder bore is clean and free of chips before seating the shank, and confirm runout with a dial indicator before beginning a cut. Verify spindle speed and feed rate are appropriate for the workpiece material and tool diameter before engaging the cut. Thermal shrink-fit and set-screw holders should meet the shank diameter tolerance range of -0.0001 to -0.0004 inches for proper grip.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-5\/8 inch (1.875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.03 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 35 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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\u003eEnd Configuration\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Micrograin Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 to -0.002500 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0.00150 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\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\u003eLength Type\u003c\/strong\u003e: Regular\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: 12179692\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51755635048754,"sku":"12179692","price":241.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2c884e8431e9f81f40e952caad0f95cc.jpg?v=1788957344","url":"https:\/\/voomisupply.com\/products\/accupro-12179692-corner-radius-end-mill-3-4-in-3-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
