With a 1 inch cutting diameter, a 1-3\/4 inch length of cut, and a 0.03 inch corner radius, this tool produces smooth corner transitions while reducing stress concentrations at part edges. The AlTiN coating provides heat resistance and extended tool life in high-temperature cutting environments. A 40-degree helix angle promotes efficient chip evacuation. This end mill is used by machinists and tool and die professionals in CNC milling centers for roughing and finishing passes on steel, stainless, and hardened workpiece materials.\u003c\/p\u003e\u003cp\u003eThis end mill suits production and job shop environments where tight corner radii and consistent surface finish are required. The single-end, centercutting design allows plunge entry as well as conventional side milling. The right-hand flute direction and right-hand cutting orientation match standard CNC spindle configurations. With a 1 inch shank diameter matching the cutting diameter, it seats directly in standard ER or side-lock holders without a reducer. Typical applications include mold and die work, aerospace component profiling, and general steel machining where a corner radius is specified on the finished part.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1 inch cutting diameter with matching 1 inch shank diameter for direct collet or holder fit\u003c\/li\u003e\n\u003cli\u003e0.03 inch corner radius reduces edge chipping and stress risers on finished parts\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for elevated heat resistance and extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003e4-flute, 40-degree helix design for efficient chip evacuation and smooth finish\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows plunge milling entry\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces harmonic chatter at higher feed rates\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use tool compatible with CNC vertical and horizontal milling machines accepting a 1 inch straight shank end mill held in standard ER collet chucks, Weldon side-lock holders, or hydraulic toolholders.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank to the full recommended insertion depth in the holder and torque set screws or collet nuts to the toolholder manufacturer specification. Verify runout with a dial indicator before beginning a cut, as excessive runout accelerates edge wear on carbide end mills.\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: 1-3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 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: 0.03 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 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: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\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: 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: 12180628\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728589553970,"sku":"12180628","price":508.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/660113b215b8626e7a5f25d6275b7da1_7364a455-e15b-461c-a4bd-bf69a3e8c6d6.jpg?v=1788693707","url":"https:\/\/voomisupply.com\/products\/accupro-12180628-corner-radius-end-mill-1-in-4-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
