It features a 0.5-inch cutting diameter, a 1.25-inch length of cut, and a 3-inch overall length with a 0.5-inch shank diameter. The micrograin carbide substrate delivers hardness and edge retention well beyond standard carbide grades. An AlTiN coating provides thermal resistance and oxidation protection, making this end mill suitable for dry or near-dry cutting in ferrous and exotic materials. Machinists and tool room technicians are the primary installers and operators of this tool.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for slotting, profiling, and peripheral milling on CNC machining centers and manual knee mills. The 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces in both shallow and moderate-depth passes. The centercutting geometry allows direct plunge entry into workpiece material. It is well matched to applications involving hardened steels, stainless, titanium, and similar difficult-to-machine alloys where heat buildup is a concern.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for superior hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlTiN finish for high-temperature oxidation resistance in ferrous and exotic alloy cutting\u003c\/li\u003e\n\u003cli\u003e40-degree spiral flute helix for aggressive chip evacuation and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting design enables direct plunge milling without a pre-drilled entry hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute configuration for standard CNC spindle compatibility\u003c\/li\u003e\n\u003cli\u003eMill diameter tolerance of +0.000 \/ -0.002 inches for close-tolerance work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard tooling choice for any CNC machining center or manual mill accepting a 0.5-inch straight shank end mill with ER, set-screw, or collet-style toolholders.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully stopped and locked before inserting or removing the tool from the holder. Verify shank seating depth and holder torque per the toolholder manufacturer specifications before initiating a cut. Confirm spindle speed and feed rate settings are appropriate for the workpiece material and cut depth before engaging the tool.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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: AlTiN\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\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\u003eWeight\u003c\/strong\u003e: 0.5 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: 12180451\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51734512337202,"sku":"12180451","price":141.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2d08b9f654e380c8b1b7c8d42e07acfc.jpg?v=1788763293","url":"https:\/\/voomisupply.com\/products\/accupro-12180451-square-end-mill-0-5-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
