It features a 0.125 inch diameter with a 0.25 inch length of cut and a 1.5 inch overall length. The three-flute geometry with a 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. An AlTiN coating provides heat resistance and extended tool life in ferrous and hardened materials. The micrograin carbide substrate adds toughness and edge retention at high cutting speeds. This tool is installed and operated by machinists and CNC programmers working with vertical machining centers and manual mills.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for stub-length milling operations where rigidity is critical and deflection must be minimized. The right-hand cut and right-hand spiral flute configuration is standard for conventional and climb milling on CNC machining centers. The centercutting design allows plunge cuts as well as peripheral and slot milling. It is commonly used in job shop, toolroom, and production environments on steel, stainless steel, cast iron, and similar ferrous alloys where an AlTiN coating delivers performance advantages over uncoated carbide.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.125 inch mill diameter with plus 0.000 inch and minus 0.002 inch diameter tolerance\u003c\/li\u003e\n\u003cli\u003eThree-flute spiral geometry with 40-degree helix for efficient chip flow\u003c\/li\u003e\n\u003cli\u003eAlTiN finish for elevated heat resistance and extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and sharp edge retention\u003c\/li\u003e\n\u003cli\u003eCentercutting design enables plunge entry without a pilot hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for standard CNC and manual mill spindle rotation\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 1\/8 inch collets or end mill holders on CNC machining centers and manual vertical mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety protocols. Secure the shank in a clean, properly sized collet or end mill holder and torque to the tool holder manufacturer specification. Confirm spindle rotation direction matches the right-hand cut orientation before engaging the workpiece. Inspect the cutting edges for chips or wear before each use and replace the tool when edge condition degrades to avoid poor surface finish or workpiece damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\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: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: plus 0.000 inches \/ minus 0.002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: minus 0.0001 inches \/ minus 0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 12182159\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730542428466,"sku":"12182159","price":22.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/148771e6a16232a0dd657f9b9fa1592e.jpg?v=1788719284","url":"https:\/\/voomisupply.com\/products\/accupro-12182159-square-end-mill-1-8-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
