It features a 1-inch cutting diameter, a 2-inch length of cut, and a 0.045-inch corner radius that reduces stress concentrations at the base of milled features and extends tool life in high-cycle applications. With 4 right-hand spiral flutes and a bright uncoated finish, this single-end, centercutting tool handles both plunge and peripheral cuts. The micrograin carbide substrate provides hardness and wear resistance suited to demanding production environments. Machinists and CNC operators in job shops and manufacturing facilities are the primary users.\u003c\/p\u003e\u003cp\u003eThis end mill is well suited for finishing and semi-finishing passes in ferrous and non-ferrous materials where a radiused bottom corner is required. The long-length body with a 6-inch overall length and 1-inch shank diameter makes it appropriate for setups requiring additional reach into deep pockets or stepped features. It is a single-end tool intended for standard spindle holders and collet chucks compatible with a 1-inch shank.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-inch cutting diameter with a 0.045-inch corner radius for reduced corner chipping and improved surface finish\u003c\/li\u003e\n\u003cli\u003e4 right-hand spiral flutes for efficient chip evacuation and smooth cutting action\u003c\/li\u003e\n\u003cli\u003eSolid micrograin carbide construction for hardness and wear resistance in demanding machining applications\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for a wide range of ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eLong-length configuration with 6-inch overall length for extended reach into deep pockets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct substitute corner radius end mill for use in standard 1-inch shank collet chucks, end mill holders, and hydraulic toolholders on CNC machining centers and manual knee mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following the toolholder manufacturer specifications for runout and clamping torque. Ensure the machine spindle is fully stopped and locked out before mounting or removing the end mill. Confirm shank engagement depth meets the toolholder minimum grip length to prevent pull-out under cutting loads. Verify that the selected spindle speed and feed rate are appropriate for the workpiece material before initiating a cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2 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: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.045 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\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\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: Long\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\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0.00150 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.51 pounds\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: 12183426\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51731912655154,"sku":"12183426","price":707.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eeacaef8fda675cdc0e750667c1b519c_9a964586-4671-4091-9e0f-00f8484a394b.jpg?v=1788736493","url":"https:\/\/voomisupply.com\/products\/accupro-12183426-corner-radius-end-mill-1-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
