It features a 1\/16 inch small end diameter, a 10-degree taper angle per side, and a 3\/4 inch length of cut. The micrograin carbide substrate and 3-flute spiral geometry support clean chip evacuation and consistent edge integrity in demanding machining environments. This tool is intended for use by machinists, toolmakers, and CNC programmers running finish and semi-finish passes on tight-tolerance work.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for die and mold work, aerospace component finishing, and general precision machining where tapered wall geometry or fine-radius ball profiles are required. The 10-degree taper per side makes it appropriate for draft angle milling and rib machining in cavities where clearance is limited. The 3\/8 inch shank diameter fits standard ER and end mill holders found on vertical machining centers and 5-axis platforms.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e10-degree taper angle per side for draft and tapered wall milling\u003c\/li\u003e\n\u003cli\u003e1\/32 inch nose radius ball end for fine-detail contouring\u003c\/li\u003e\n\u003cli\u003e3-flute spiral design with right-hand flute direction for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eCentercutting capable  -  supports plunge and ramp entry moves\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for use with cutting fluids in ferrous and non-ferrous applications\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle balances cutting forces on light radial passes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-shank tapered ball end mill with a 3\/8 inch shank diameter, compatible with ER collet chucks, shrink-fit holders, and end mill holders sized for 3\/8 inch tooling on CNC vertical and horizontal machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop toolholding procedures. Ensure the spindle is fully stopped and the machine is in an e-stop or lockout state before changing tooling. Confirm proper runout with a dial indicator after seating the tool in the holder, as excessive runout will degrade edge life and surface finish. Consult the machine manufacturer and tooling supplier documentation for recommended speeds and feeds based on workpiece material and depth of cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmall End Diameter\u003c\/strong\u003e: 1\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTaper Angle Per Side\u003c\/strong\u003e: 10 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 1\/32 inches\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\u003eEnd Shape\u003c\/strong\u003e: Ball\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\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\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: 12177666\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51741571088690,"sku":"12177666","price":169.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0fd13bad579d4054f50500afbb704ab4.jpg?v=1788832257","url":"https:\/\/voomisupply.com\/products\/accupro-12177666-tapered-ball-end-mill-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
