The 0.2188 inch (7\/32 inch) cutting diameter, combined with an AlTiN coating and micrograin carbide substrate, makes this tool suitable for high-speed dry machining and interrupted cuts where heat resistance and edge retention are critical. Four flutes with a variable helix geometry improve chip evacuation and reduce chatter, supporting consistent surface finishes across steel, stainless, cast iron, and high-temperature alloys. This end mill is centercutting, allowing plunge entry when the application requires it.\u003c\/p\u003e\u003cp\u003eThis corner chamfer end mill is applied in CNC machining centers and manual mills where controlled chamfer geometry is required at part edges, countersink lead-ins, or deburring operations. The 45-degree chamfer angle and 0.0100 inch chamfer width produce consistent, repeatable edge breaks on close-tolerance workpieces. It is a single-end tool with a 1\/4 inch straight shank, fitting standard ER collets and end mill holders common in production and job shop environments. Machinists and toolroom technicians working in aerospace, automotive, and general metalworking applications are the primary users.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for wear resistance and long tool life in hard materials\u003c\/li\u003e\n\u003cli\u003eAlTiN coating provides high-temperature oxidation resistance for dry and high-speed cutting\u003c\/li\u003e\n\u003cli\u003eVariable helix flute geometry reduces harmonics and chatter during cutting\u003c\/li\u003e\n\u003cli\u003e45-degree chamfer angle with 0.0100 inch chamfer width for precise edge preparation\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand spiral with single-end configuration for versatile CNC use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard single-end corner chamfer end mill with a 1\/4 inch shank, compatible with ER collet chucks and end mill holders accepting 1\/4 inch straight shanks 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 or CNC tooling technician. Ensure the spindle is fully stopped and the machine is powered down or in a safe tool-change state before inserting or removing the end mill. Seat the shank fully within the collet or holder to the recommended minimum engagement depth for the holder type in use. Verify runout with a dial indicator before initiating a cutting cycle to protect both the tool and the workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.2188 inches (7\/32 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.002 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: 0.7500 inches (3\/4 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches (2-1\/2 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 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\u003eChamfer Width\u003c\/strong\u003e: 0.0100 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Angle\u003c\/strong\u003e: 45 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: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: Variable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: 95168525\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51729308123442,"sku":"95168525","price":79.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e071a9846fc01c014be8be91defa1d06.jpg?v=1788702714","url":"https:\/\/voomisupply.com\/products\/accupro-95168525-corner-chamfer-end-mill-4-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
