Built with four flutes, a 40-degree helix angle, and an integrated chipbreaker geometry, it breaks chips efficiently to reduce heat and tool pressure during cut. The square end profile produces flat-bottomed features and sharp shoulder transitions. At 0.25 inches in diameter with a 0.375-inch length of cut and a 2-inch overall length, this is a stub-length tool optimized for rigidity in tight-clearance milling applications. Micrograin carbide substrate provides wear resistance and edge retention on a wide range of materials. The bright, uncoated finish suits general-purpose use where coating compatibility or cost is a factor.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for CNC machining centers and manual knee mills where operators need a single tool to rough and finish in one pass or in sequential light passes. The stub length and straight shank make it a reliable choice for shallow-pocket milling, slotting, and profiling operations in ferrous and non-ferrous metals, plastics, and composites. It is centercutting, allowing plunge entry without a pre-drilled pilot hole. Right-hand flute direction and right-hand cutting orientation are standard for conventional and climb milling setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eChipbreaker geometry reduces chip load and heat buildup during roughing passes\u003c\/li\u003e\n\u003cli\u003eFour-flute, 40-degree helix angle for efficient chip evacuation and smooth finish\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for edge retention and wear resistance\u003c\/li\u003e\n\u003cli\u003eStub-length construction improves rigidity and reduces deflection in short-reach applications\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish for general-purpose compatibility across a broad range of workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose replacement or stock end mill for CNC machining and manual milling applications requiring a 1\/4-inch straight shank, square-end, four-flute roughing and finishing tool.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or CNC operators using a compatible collet, end mill holder, or set-screw tool holder sized for a 1\/4-inch straight shank. Confirm runout and holder concentricity before use to protect the cutting edge. Always power down and lock out the spindle before changing tooling. Follow machine manufacturer feed and speed recommendations for the workpiece material; do not exceed the tool's stated length of cut of 0.375 inches to avoid deflection or breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 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\u003eLength of Cut\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.051 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: 12185422\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51729679319346,"sku":"12185422","price":55.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7783145f5d37432152066b8edf6007b0.jpg?v=1788707689","url":"https:\/\/voomisupply.com\/products\/accupro-12185422-1-4-in-4-flute-carbide-end-mill","provider":"Voomi Supply","version":"1.0","type":"link"}
