Built from micrograin solid carbide and coated with AlTiN (Aluminum Titanium Nitride), it handles high-heat cutting environments where tool life and surface finish matter. The 1 inch cutting diameter, 1.75 inch length of cut, and 0.015 inch corner radius make it well-suited for profiling, slotting, and contouring operations that require a controlled edge break. The 40-degree helix angle improves chip evacuation and reduces cutting forces. This tool is installed by machinists and CNC operators in job shop and production environments.\u003c\/p\u003e\u003cp\u003eThis end mill is used in vertical and horizontal machining centers for medium to finishing passes on hardened steels, stainless alloys, and titanium. The centercutting geometry allows plunge entry into the workpiece. The right-hand flute direction and right-hand cutting direction are standard for conventional CNC setups. With a 1 inch shank diameter and 4 inch overall length, it fits standard collet and side-lock toolholders without an extension.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide substrate for rigidity and wear resistance in high-temp alloys\u003c\/li\u003e\n\u003cli\u003eAlTiN coating extends tool life in dry and semi-dry cutting of ferrous materials\u003c\/li\u003e\n\u003cli\u003e0.015 inch corner radius reduces chipping at the cutting edge and improves part finish\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes efficient chip evacuation and smooth cutting action\u003c\/li\u003e\n\u003cli\u003eCentercutting design permits direct plunge milling without a pre-drilled entry hole\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with right-hand cut and right-hand spiral flute direction\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use end mill for CNC machining centers accepting a 1 inch straight shank in standard collet, Weldon, or milling chuck toolholders.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes must be performed with the machine spindle fully stopped and the control in a safe state per shop lockout\/tagout procedures. Ensure the shank is seated to the full recommended grip depth in the toolholder and that runout is verified with a dial indicator before the first cut. Consult the toolholder manufacturer's torque specifications for set screws or collet nuts. Do not exceed the tool's rated depth of cut or feed rate for the workpiece material.\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: 1.75 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\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: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0.0015 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\u003eWeight\u003c\/strong\u003e: 2 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: 12176838\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51739483898162,"sku":"12176838","price":464.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/895a7d242358373d314ebb950df7c39c.jpg?v=1788815096","url":"https:\/\/voomisupply.com\/products\/accupro-12176838-corner-radius-end-mill-1-in-2-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
