Built from micrograin carbide and coated with AlTiN (aluminum titanium nitride), it handles high-heat cutting environments where tool life and edge integrity matter. The 0.06-inch corner radius reduces stress concentration at the cutting edge and produces a controlled radius on workpiece corners. With a 1-inch diameter, 1.75-inch length of cut, and a 40-degree helix angle, this end mill delivers efficient chip evacuation and smooth surface finishes in demanding production and tool-and-die applications. Licensed machinists and CNC operators are the primary installers and users.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for CNC milling centers running high-speed or conventional milling passes in steel, stainless steel, cast iron, and similar hard materials. The single-end, centercutting configuration allows both peripheral and plunge cutting. The right-hand flute direction and right-hand cutting geometry are standard for conventional vertical and horizontal machining center spindles. The 1-inch shank diameter fits standard toolholders, collets, and end mill holders sized for 1-inch shanks. It is commonly used in mold and die work, fixture machining, and precision part production.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiN coating provides high heat resistance and extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003e0.06-inch corner radius reduces edge chipping and produces consistent corner geometry\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes efficient chip evacuation and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting design enables plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eSingle-end construction with right-hand cut and right-hand spiral flutes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard CNC milling machines and machining centers accepting a 1-inch shank diameter end mill holder, collet chuck, or hydraulic toolholder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and operation of this end mill should be performed by qualified machinists or CNC operators. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before loading or removing the tool from the toolholder. Verify that the toolholder bore and collet are clean and free of chips before seating the shank. Follow machine manufacturer torque specifications for drawbar or set-screw retention — do not overtighten or undertighten the retention mechanism.\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\u003eShank 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\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.06 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\u003c\/strong\u003e: AlTiN\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\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\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\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 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: 12182371\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51736014422322,"sku":"12182371","price":382.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/037e2aae291780587b0ae4e4429db8ed.jpg?v=1788775422","url":"https:\/\/voomisupply.com\/products\/accupro-12182371-corner-radius-end-mill-1-in-4-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
