With a 7-degree taper angle per side and a 3-flute spiral configuration, this tool produces clean, accurate cuts in a range of workpiece materials. The small end diameter measures 3\/16 inches, the length of cut is 1-1\/4 inches, and the overall length is 3-1\/4 inches. The 1\/2 inch shank diameter provides a stable interface with standard toolholders. The uncoated micrograin carbide construction is suited for general-purpose machining where tool geometry precision is the priority.\u003c\/p\u003e\u003cp\u003eThis tapered end mill is used in CNC machining centers and manual milling applications where tapered walls, draft angles, or die and mold geometries are required. Typical applications include finishing tapered slots, machining draft angles in mold cavities, and profiling workpieces in ferrous and non-ferrous materials. The square end geometry and center-cutting capability allow it to be used for both plunge entry and peripheral cutting. It is commonly specified by machinists and tool-and-die makers working in job shop, mold shop, and production machining environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7-degree taper angle per side for accurate draft geometry\u003c\/li\u003e\n\u003cli\u003e3\/16 inch small end diameter with 1-1\/4 inch length of cut\u003c\/li\u003e\n\u003cli\u003e3-flute spiral design with 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capability allows direct plunge entry\u003c\/li\u003e\n\u003cli\u003eRight-hand flute direction with square end geometry\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for general-purpose milling applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling selection for CNC machining centers and manual mills accepting a 1\/2 inch shank diameter end mill holder or collet chuck.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the tool changer or spindle is locked out before inserting or removing the end mill. Seat the shank fully in the collet or toolholder to the recommended grip depth and torque the retention mechanism per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning cutting operations to protect both the tool and the workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmall End Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/4 inches (1.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTaper Angle Per Side\u003c\/strong\u003e: 7 degrees\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: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Shape\u003c\/strong\u003e: Square\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\/Finish\u003c\/strong\u003e: Uncoated\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: 12177539\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51740259320114,"sku":"12177539","price":141.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/36de699da9f46c4273500fcff1257477.jpg?v=1788823824","url":"https:\/\/voomisupply.com\/products\/accupro-12177539-tapered-end-mill-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
