It features a 1\/8 inch diameter with a 0.01 inch corner radius and a 1\/2 inch length of cut, making it well suited for finishing passes and contour milling where a sharp corner break is required. The 3-flute geometry with a 35-degree helix angle promotes efficient chip evacuation and smooth surface finishes. A TiCN (titanium carbonitride) coating increases surface hardness and wear resistance compared to uncoated carbide, extending tool life in ferrous and non-ferrous materials. This is a single-end, centercutting tool, so it can be plunged directly into the workpiece.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in CNC machining centers, vertical mills, and manual knee mills for slotting, profiling, and pocket milling. The small diameter and short length of cut make it a practical choice for detail work, die and mold applications, and tight-tolerance features in aluminum, steel, stainless, and cast iron. The right-hand cutting direction and right-hand flute spiral are standard for conventional CNC setups. Machinists and tool-and-die makers working in job shops or production environments are the primary users.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/8 inch cutting diameter with 0.01 inch corner radius for controlled edge break on finished surfaces\u003c\/li\u003e\n  \u003cli\u003eTiCN coating for improved hardness and wear resistance over uncoated carbide\u003c\/li\u003e\n  \u003cli\u003e3-flute design with 35-degree helix angle for balanced chip load and smooth finish\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide construction for rigidity and dimensional stability in demanding cuts\u003c\/li\u003e\n  \u003cli\u003e1\/8 inch shank diameter matches standard collet sizes for straightforward toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard tooling option for CNC machining centers and manual mills accepting a 1\/8 inch shank collet or end mill holder.

Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before inserting or removing the tool from the collet or toolholder. Seat the shank to the recommended insertion depth per the toolholder manufacturer's specification and torque the collet nut with the appropriate spanner wrench. Verify runout with a dial indicator before beginning any cut, as excessive runout accelerates wear and can cause premature tool failure on small-diameter carbide end mills.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.01 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: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch\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\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\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\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\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\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.0001 to -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.25 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 12179659\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51739756527922,"sku":"12179659","price":17.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6e9e569efc37de99c10c8e8a6b062201_f4042491-c587-48e0-9be6-211d148152a0.jpg?v=1788818556","url":"https:\/\/voomisupply.com\/products\/accupro-12179659-corner-radius-end-mill-1-8-in-3-flute-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
