Built from micrograin carbide stock, it carries a TiCN (titanium carbonitride) finish that increases surface hardness and wear resistance compared to uncoated tooling. At 0.4531 inches in diameter with a 40-degree helix angle and spiral flute geometry, it delivers aggressive chip evacuation and smooth cutting action. The stub-length configuration keeps deflection low in tight-clearance setups. This is a single-end, centercutting tool, meaning it can plunge directly into a workpiece. Machinists, tool-and-die makers, and CNC operators install this class of end mill in vertical and horizontal machining centers.\u003c\/p\u003e\u003cp\u003eThis end mill suits general-purpose profiling, slotting, and plunging operations in shop and production environments. Its 5\/8-inch length of cut suits shallow-to-medium-depth passes, and the 1\/2-inch shank diameter fits standard ER and side-lock toolholders found on most CNC knee mills and machining centers. The right-hand cut and right-hand flute configuration is consistent with conventional milling setups. It is appropriate for applications in steel, stainless, cast iron, and non-ferrous alloys where a stub overhang and micrograin carbide substrate are preferred for rigidity and tool life.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide substrate for extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003eTiCN coating adds wear resistance and reduces built-up edge\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes efficient chip evacuation and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eStub length type minimizes deflection in short-reach milling setups\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for conventional CNC milling setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard tooling selection for 1\/2-inch shank ER collet chucks, side-lock holders, and shrink-fit toolholders used in CNC machining centers and manual knee mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. The machine spindle must be fully stopped and the machine placed in an e-stop or locked-out state before changing tooling. Torque the toolholder to the toolholder manufacturer specifications using a calibrated torque wrench. Verify runout with a dial indicator after installation and before cutting to confirm acceptable concentricity for the intended operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 29\/64 inch (0.4531 inches)\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: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches (2.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin Grade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\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\u003eLength Type\u003c\/strong\u003e: Stub\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\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\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: 12181684\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51748724310322,"sku":"12181684","price":112.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9fb2250e3c5fb4f30f2f93a055730990.jpg?v=1788897326","url":"https:\/\/voomisupply.com\/products\/accupro-12181684-square-end-mill-29-64-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
