It features a 0.750 inch mill diameter, a 3 inch length of cut, and a 0.1250 inch corner radius that reduces stress concentration at the cutting edge and extends tool life in slotting and profiling operations. The TiCN coating adds surface hardness and lubricity, making it well suited for harder workpiece materials. With a 4-flute, right-hand spiral configuration and centercutting capability, this tool handles both plunge entry and lateral passes. Machinists and toolroom professionals select this end mill for applications that demand tight tolerances and consistent edge geometry on long-reach cuts.\u003c\/p\u003e\n\u003cp\u003eThis end mill is built for shops running CNC machining centers, vertical mills, and similar equipment where extra-long reach is required. The 6 inch overall length and 3\/4 inch shank diameter make it appropriate for deep-cavity milling, mold work, and multi-axis profiling where shorter tooling cannot clear the workpiece or fixture. The micrograin carbide substrate supports the rigidity needed to maintain accuracy across the full 3 inch length of cut. It is a single-end tool intended for production and toolroom environments where repeatable surface finish and dimensional control are priorities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.1250 inch corner radius reduces edge chipping and stress risers on milled profiles\u003c\/li\u003e\n  \u003cli\u003eTiCN coating improves wear resistance and performance in harder alloy steels\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate provides rigidity across the extra-long 3 inch length of cut\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes efficient chip evacuation and smooth cutting action\u003c\/li\u003e\n  \u003cli\u003eRight-hand flute direction and right-hand cutting for standard CNC spindle operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and manual vertical mills with a standard 3\/4 inch collet or end mill holder.

Power down and lock out the spindle before loading or removing tooling. Seat the shank fully in a properly sized collet or end mill holder and torque the retention hardware to the tool holder manufacturer's specification. Verify runout at the cutting end with a dial indicator before beginning production cuts.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.1250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.750 inches\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: 40 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: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\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\u003eLength Type\u003c\/strong\u003e: Extra Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 \/ -0.002500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0.00150 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: 1 pound\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: 12183374\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730106908978,"sku":"12183374","price":420.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd3c1b00cb72750041aa5b3dc6557ca6.jpg?v=1788711847","url":"https:\/\/voomisupply.com\/products\/accupro-12183374-corner-radius-end-mill-3-4-in-4-flute-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
