It features a 3\/4-inch diameter, a 1-5\/8-inch length of cut, and a 4-inch overall length. The cutting end has a 0.090-inch corner radius that blends floor-to-wall transitions and reduces stress concentrations at part edges. A ZrN (zirconium nitride) coating adds surface hardness and heat resistance, extending tool life in demanding cuts. The 37-degree helix angle and three-flute, right-hand spiral geometry promote chip evacuation and smooth cutting action. Centercutting capability allows plunge entry. This tool is used by machinists and tool-and-die professionals in CNC milling applications.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for roughing and finishing operations on ferrous and non-ferrous workpiece materials in production and job-shop CNC machining environments. The micrograin solid carbide substrate supports high-speed cutting parameters and holds tight tolerances over extended run times. The single-end, regular-length configuration fits standard ER and side-lock toolholders with a 3\/4-inch bore. It is appropriate for vertical and horizontal machining centers where controlled corner blending and floor finish are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.090-inch corner radius reduces stress risers and blends floor-to-wall transitions\u003c\/li\u003e\n  \u003cli\u003eZrN coating increases surface hardness and thermal resistance for longer tool life\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate supports tight tolerances at high cutting speeds\u003c\/li\u003e\n  \u003cli\u003eThree-flute, 37-degree right-hand spiral geometry promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eSingle-end, regular-length profile fits standard 3\/4-inch CNC toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-specification solid carbide corner radius end mill for CNC machining centers accepting a 3\/4-inch shank diameter toolholder.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and the tool is de-energized before changing tooling. Seat the shank fully into a clean, undamaged collet or side-lock holder and torque the retention hardware to the toolholder specification. Verify runout with a dial indicator before initiating a cut program.\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 inches (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-5\/8 inches (1.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0900 inches\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: 37 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: ZrN (Zirconium Nitride)\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\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\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: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 \/ -0.002000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.0001 \/ -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.75 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: 314998\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732371243314,"sku":"314998","price":306.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9e65fd014f30a540bb583a61b5c1db08.jpg?v=1788742173","url":"https:\/\/voomisupply.com\/products\/accupro-314998-corner-radius-end-mill-3-4-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
