It features a 3\/8 inch diameter, a 1-1\/2 inch length of cut, and a 0.015 inch corner radius that reduces stress concentrations at the cutting edge and extends tool life in demanding cuts. Built from micrograin solid carbide and finished with a TiCN coating, this end mill handles abrasive materials and elevated cutting temperatures better than uncoated tools. The 40-degree helix promotes efficient chip evacuation, and the centercutting geometry allows plunge milling when needed. Machinists and tool-and-die professionals working in job shops, production facilities, and maintenance departments are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling steel, stainless steel, cast iron, and similar ferrous materials where a corner radius profile is required to blend floor-to-wall transitions or meet a part print callout. The extra-long 6 inch overall length gives additional reach for deep-pocket or tall-workpiece setups where a standard-length tool cannot access the feature. Right-hand cutting and right-hand flute direction are standard for conventional CNC milling center spindles. Single-end construction means it is replaced rather than reground when worn, keeping setup times predictable.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide substrate delivers hardness and rigidity for tight-tolerance work\u003c\/li\u003e\n  \u003cli\u003eTiCN coating improves wear resistance and reduces heat buildup at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e0.015 inch corner radius reduces edge chipping and blends floor-to-wall transitions\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes smooth chip flow out of deep pockets\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eExtra-long 6 inch OAL provides reach for deep-pocket and tall-fixture applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use cutting tool for CNC machining centers and manual mills equipped with a 3\/8 inch collet, end mill holder, or compatible toolholder accepting a 3\/8 inch straight shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician familiar with CNC or manual milling equipment. Ensure the machine spindle is fully stopped and the tool change mode is engaged before loading or unloading the end mill. Seat the shank to the full recommended engagement depth in the holder to minimize runout and prevent pull-out under cutting loads. Verify tool projection and runout with a dial indicator before beginning a cut, especially given the extra-long OAL which increases deflection sensitivity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/2 inches (2.2500 inches decimal)\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: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.015 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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 to -0.002500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inches\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: Micrograin Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\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\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\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\u003eExtended Reach\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\u003eLength Type\u003c\/strong\u003e: Extra Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.34 pounds\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: 12183699\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51736806818098,"sku":"12183699","price":158.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2d5702321fcb73c1d329c3cbaaf21c1a_c71aa6de-862a-4e5d-93ed-56fe82651367.jpg?v=1788780587","url":"https:\/\/voomisupply.com\/products\/accupro-12183699-corner-radius-end-mill-3-8-in-4-flute-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
