It features a 3\/4 inch mill diameter, a 1 inch length of cut, and a 0.0300 inch corner radius that reduces stress concentrations at the cutting edge. The 4-flute, right-hand spiral configuration and 38-degree helix angle promote efficient chip evacuation and smooth finishes. An AlCrTiN coating extends tool life in high-heat, high-speed cutting environments. This is a centercutting tool, meaning it can plunge directly into the workpiece. Machinists and toolroom professionals install this type of end mill on CNC machining centers and manual knee mills.\u003c\/p\u003e\u003cp\u003eThis end mill is well suited for finishing and semi-finishing passes in ferrous and exotic alloy materials where edge quality and dimensional accuracy are critical. The 3\/4 inch Smart-Weldon shank provides secure, repeatable toolholding in compatible holders. The extended reach design and stub-length classification make it appropriate for pockets and shoulders where access depth must be balanced against rigidity. The 4 inch overall length suits standard toolholding setups on vertical machining centers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.0300 inch corner radius reduces edge chipping and extends tool life in profiling operations\u003c\/li\u003e\n\u003cli\u003eAlCrTiN coating provides thermal and oxidation resistance for high-speed dry or near-dry cutting\u003c\/li\u003e\n\u003cli\u003e4-flute right-hand spiral with 38-degree helix for efficient chip flow and surface finish quality\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eUltra fine micrograin solid carbide substrate for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eSmart-Weldon shank for enhanced gripping and reduced runout in compatible toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and milling machines equipped with toolholders accepting a 3\/4 inch Smart-Weldon or standard round shank.

Power down and lock out the spindle before inserting or removing tooling. Ensure the shank is fully seated and the toolholder collet or set screw is torqued according to the toolholder manufacturer specifications. Confirm runout is within acceptable limits using a dial indicator before beginning a cut; the maximum TIR for this tool is 0.0004 inches.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch (1.0000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches (4.0000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0300 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: +0.00000 to -0.00100 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 \/ -0.001000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch (19.05 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Ultra Fine Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlCrTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Smart-Weldon\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\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\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum TIR\u003c\/strong\u003e: 0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: ST\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: 95139143\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738801602866,"sku":"95139143","price":409.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/635573341b1d98769d7835b6b76b4de4.jpg?v=1788804700","url":"https:\/\/voomisupply.com\/products\/accupro-95139143-corner-radius-end-mill-3-4in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
