Built from micrograin carbide, it delivers consistent edge integrity at higher speeds and feeds than high-speed steel alternatives. The 40-degree spiral helix promotes efficient chip evacuation and reduces cutting forces. At 0.3125 inches in diameter with a 0.625-inch length of cut, this is a single-end, uncoated tool with a right-hand cut and right-hand flute orientation. It is centercutting, which allows plunge entry without a pre-drilled pilot hole. Licensed machinists, toolroom operators, and CNC programmers will recognize this as a straightforward long-reach finishing and slotting tool.\u003c\/p\u003e\u003cp\u003eThe 12177158 is suited for precision slot milling, profiling, and pocketing operations on CNC machining centers and manual mills. The long overall length of 4 inches and an extended reach of 2-5\/8 inches make it appropriate for reaching into deep cavities or past fixtures where a standard-length end mill cannot clear. The uncoated micrograin carbide construction works well in applications where post-processing or re-coating is part of the shop workflow, or where coating compatibility with the workpiece material is a concern.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for edge retention and wear resistance\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes efficient chip flow and reduces heat buildup at the cutting edge\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry into workpiece material\u003c\/li\u003e\n\u003cli\u003eExtended reach of 2-5\/8 inches enables access to deep pockets and obstructed features\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand spiral flute — standard orientation for CNC and manual milling\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for dry cutting or wet coolant applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide square end mill for use in standard 5\/16-inch collets or end mill holders on CNC machining centers, manual knee mills, and toolroom machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician familiar with proper end mill holding practices. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before inserting or removing tooling. Use a properly sized collet or end mill holder that matches the 0.3125-inch shank diameter and torque the retention mechanism to the machine manufacturer's specification. Inspect the cutting edges for chips or wear before each use; carbide end mills are brittle and should not be dropped or used with excessive runout in the holder.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut Range\u003c\/strong\u003e: 0.6000 - 0.7000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 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\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 2-5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.75 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: 12177158\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738313621810,"sku":"12177158","price":89.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a652710355dceedf8320e36e573dc937.jpg?v=1788798142","url":"https:\/\/voomisupply.com\/products\/accupro-12177158-square-end-mill-5-16-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
