Built from micrograin solid carbide with a TiCN (Titanium Carbonitride) coating, it delivers extended tool life and improved wear resistance in ferrous and non-ferrous materials. The 0.2188-inch cutting diameter and 0.0200-inch corner radius reduce stress concentrations at part edges, producing clean, radiused transitions without secondary operations. A 35-degree helix angle promotes efficient chip evacuation and smoother cutting action. This tool is sold as a single-end, centercutting end mill, meaning it can be plunged directly into workpiece material.\u003c\/p\u003e\u003cp\u003eThis end mill fits standard CNC machining centers, vertical mills, and manual milling machines equipped with a 1\/4-inch collet or toolholder. The stub-length geometry, with a 3\/8-inch length of cut and 2-inch overall length, provides rigidity for finish milling, contouring, slotting, and profiling in tight-clearance setups. It is suited for shops and toolrooms performing precision detail work in steel, stainless, cast iron, and similar materials where corner integrity and dimensional accuracy are critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eTiCN coating improves surface hardness and reduces friction at the cutting edge\u003c\/li\u003e\n\u003cli\u003e0.0200-inch corner radius reduces edge chipping and stress at workpiece corners\u003c\/li\u003e\n\u003cli\u003e35-degree helix angle promotes smooth cutting and efficient chip flow\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry into workpiece material\u003c\/li\u003e\n\u003cli\u003eRight-hand flute direction and right-hand cutting for standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in any milling machine or CNC machining center equipped with a 1\/4-inch collet, end mill holder, or compatible toolholder accepting a 1\/4-inch shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the collet or toolholder to the minimum insertion depth recommended by the toolholder manufacturer, and verify runout with a dial indicator before beginning cuts. Follow applicable shop safety procedures for high-speed rotating cutting tools.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.2188 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 to -0.002000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0200 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.3750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2500 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\u003eHelix Angle\u003c\/strong\u003e: 35 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: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\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\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\u003eWeight\u003c\/strong\u003e: 0.25 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: 12176675\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51743302091058,"sku":"12176675","price":22.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/28b5b608e4da113cc0dc04cfc5329cd2.jpg?v=1788845334","url":"https:\/\/voomisupply.com\/products\/accupro-12176675-corner-radius-end-mill-0-2188-in-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
