Built from micrograin solid carbide, this tool delivers the rigidity and wear resistance needed for tight-tolerance work in ferrous and non-ferrous materials. It features a 3-degree taper per side, a 1\/8 inch small end diameter, and a 1\/16 inch nose radius. With 3 spiral flutes in a right-hand cut direction and a 30-degree helix angle, it provides efficient chip evacuation and smooth surface finishes. This tool is centercutting, enabling plunge entry and ramp milling without a pre-drilled start hole.\u003c\/p\u003e\u003cp\u003eThe 12177620 is suited for die and mold work, engraving, 3D contouring, and detail finishing passes where a tapered profile is required to reach restricted geometries. The 1-1\/4 inch length of cut provides adequate reach for moderate-depth cavities while maintaining tool rigidity. The 1\/4 inch shank fits standard collets and tool holders common to CNC machining centers and manual mills. The uncoated finish makes it appropriate for use in applications where coatings are not required or where re-sharpening is anticipated.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for hardness and dimensional stability\u003c\/li\u003e\n\u003cli\u003e3-degree taper per side for tapered wall milling and draft-angle profiling\u003c\/li\u003e\n\u003cli\u003eBall end with 1\/16 inch nose radius for 3D contouring and blending operations\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge and ramp entry\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle with right-hand spiral flutes promotes efficient chip flow\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for non-ferrous materials and applications requiring re-sharpening\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1\/4 inch shank tapered ball end mill compatible with CNC machining centers, vertical mills, and similar equipment using ER collet systems or other 1\/4 inch tool holders.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool should be installed by a qualified machinist or CNC setup technician familiar with cutting tool runout tolerances and collet torque procedures. Ensure the machine spindle is fully stopped and locked before changing tooling. Verify tool holder cleanliness and proper collet seating to minimize runout, which directly affects tool life and surface finish on tapered and ball-end operations. Always confirm feed rates and spindle speeds are appropriate for the workpiece material before initiating a cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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\u003eEnd Shape\u003c\/strong\u003e: Ball\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmall End Diameter\u003c\/strong\u003e: 1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 1\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTaper Angle Per Side\u003c\/strong\u003e: 3 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\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: 12177620\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51727858204978,"sku":"12177620","price":137.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b2cac41cb948b1d4fef64a5376eb2678.jpg?v=1788683589","url":"https:\/\/voomisupply.com\/products\/accupro-12177620-tapered-ball-end-mill-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
