Built from micrograin solid carbide, this stub-length tool features a 1\/8 inch cutting diameter, a 1\/4 inch length of cut, and a 3-flute spiral configuration with a 40-degree helix angle. The right-hand cut and right-hand flute geometry promote efficient chip evacuation and smooth surface finishes. At 1-1\/2 inches overall length with a 1\/8 inch shank, this end mill is suited for tight-clearance work and light profiling passes on CNC mills and manual machining centers. It is installed and used by machinists and tool-and-die professionals.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in general-purpose milling operations including slotting, profiling, and contouring on ferrous and non-ferrous materials. The stub length design improves rigidity and reduces deflection during aggressive cuts at shallow depths. The centercutting configuration allows the tool to plunge directly into the workpiece, adding versatility for pocketing operations. The uncoated micrograin carbide substrate is appropriate for applications where a base carbide edge is preferred or where coatings are not required by the material or process specification.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for wear resistance and edge retention\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle spiral flute promotes efficient chip flow and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute configuration for standard CNC and manual spindle use\u003c\/li\u003e\n\u003cli\u003eStub length body improves tool rigidity and minimizes deflection in tight setups\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for applications where coating is not required\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1\/8 inch shank square end mill compatible with collet chucks, end mill holders, and tool holders sized for 1\/8 inch shank diameter on CNC machining centers and manual mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following standard toolholding procedures. Ensure the spindle is fully powered down and the machine is in a safe state before changing tooling. Secure the shank fully within the collet or holder to the recommended gauge-line depth to prevent pullout during cutting. Verify runout with a dial indicator before beginning production cuts, as micrograin carbide tools are sensitive to excessive runout and improper clamping.\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\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: 0.250 inches (1\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.500 inches (1-1\/2 inches)\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\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 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\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\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\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\u003eCoating\u003c\/strong\u003e: Uncoated\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: 12182157\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728198205746,"sku":"12182157","price":18.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6a944aa524f2f35b31e34aaf0bc46d8d.jpg?v=1788689383","url":"https:\/\/voomisupply.com\/products\/accupro-12182157-square-end-mill-1-8-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
