Part of the Runner Cutters series, it features a 45-degree taper angle per side and a 0.03-inch small end diameter with a 1\/64-inch nose radius, making it well-suited for fine detail work in hardened materials. The AlTiN coating improves heat resistance and tool life at elevated cutting temperatures. With 2 flutes and a 12-degree helix angle, this mill provides clean chip evacuation in tight geometries. It is installed and run by machinists and tool-and-die professionals on CNC milling equipment.\u003c\/p\u003e\u003cp\u003eThis tapered end mill is used in mold making, die machining, and precision part manufacturing where angled walls and tight radii must be held to close tolerances. The 0.119-inch length of cut allows controlled engagement in shallow-to-moderate pockets, while the 2.5-inch overall length provides adequate reach for most cavity work. It is suited for use in vertical and horizontal CNC machining centers on ferrous and non-ferrous materials where an AlTiN coating provides the most benefit, including hardened steels and alloys.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e45-degree taper angle per side for angled wall and draft-angle milling\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for extended tool life in hardened and abrasive materials\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003e1\/64-inch nose radius ball end for fine detail and contour work\u003c\/li\u003e\n\u003cli\u003e12-degree helix angle supports efficient chip flow in tapered geometries\u003c\/li\u003e\n\u003cli\u003e1\/4-inch shank diameter fits standard CNC collets and toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and precision cutting tool compatible with CNC machining centers accepting a 1\/4-inch shank end mill in standard ER or precision collet toolholding systems.

Secure the 1\/4-inch shank in a precision collet or toolholder to the manufacturer-specified runout tolerance before operation. Verify spindle speed and feed rate parameters against the material being cut and the tool manufacturer's recommendations before engaging the workpiece. Do not exceed the listed length of cut during full-engagement passes.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmall End Diameter\u003c\/strong\u003e: 0.03 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 0.119 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.0156 inches (1\/64 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTaper Angle Per Side\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 12 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Shape\u003c\/strong\u003e: Ball\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Runner Cutters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: HARVEY TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 856500-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51740478570802,"sku":"856500-C3","price":122.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ce692f37cfc4380870c8d44f9cf01a61_631c13ff-49de-4f0f-861b-401cdccd587e.jpg?v=1788825276","url":"https:\/\/voomisupply.com\/products\/harvey-tool-856500-c3-tapered-ball-end-mill-altin-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
