The 1\/8 inch cutting diameter paired with a 40-degree helix angle and TiCN (Titanium Carbonitride) finish delivers improved chip evacuation and extended tool life in demanding cutting environments. With a 1 inch length of cut and 1-1\/2 inch overall length, this is an extra-long configuration suited for reaching into slots, pockets, and stepped features where shorter tooling falls short. Machinist and tool and die professionals rely on this geometry for finishing passes and tight-tolerance work in CNC mills and machining centers.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in light to medium milling applications on ferrous and non-ferrous workpiece materials. The centercutting design allows plunge entry directly into a workpiece, making it suitable for slot milling, profile milling, and pocket operations. The right-hand cut and right-hand spiral flute configuration is standard for conventional CNC spindle setups. The micrograin carbide substrate provides rigidity at small diameters where high-speed steel tooling loses accuracy under load.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiCN finish for improved surface hardness and wear resistance over uncoated carbide\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes smooth chip flow and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting capable — supports plunge milling without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate maintains dimensional stability at 1\/8 inch diameter\u003c\/li\u003e\n\u003cli\u003eExtra-long length of cut (1 inch) extends reach into deep slots and pockets\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute — compatible with standard CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for CNC machining centers and manual mills using 1\/8 inch collets or ER-style tool holders with 1\/8 inch bore capacity.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully powered down and the machine is in a safe state before changing tooling. Secure the shank in a collet or end mill holder to the full recommended engagement depth to minimize runout and prevent pullout under cutting loads. Do not exceed the tool manufacturer recommended speeds and feeds for the workpiece material and cut depth.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\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 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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Extra Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.0025 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\u003ePackage Weight\u003c\/strong\u003e: 0.04 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: 12178827\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51737565167922,"sku":"12178827","price":46.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b5e14471de32f40267a54d4721768140.jpg?v=1788790491","url":"https:\/\/voomisupply.com\/products\/accupro-12178827-square-end-mill-1-8-in-2-flute-carbide-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
