It features a 15-degree taper angle per side, a small end diameter of 0.1250 inches, and a 0.4670-inch length of cut. The three-flute, right-hand helical configuration provides efficient chip evacuation while maintaining surface finish quality. Built from micrograin solid carbide, this tool delivers the rigidity and edge retention required when working through tough workpiece materials. It ships in a bright, uncoated finish and is suited for machinists, toolroom operators, and CNC programmers who need a reliable tapered profile cutter.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for milling tapered slots, die cavities, engraving paths, and angled wall features in ferrous and high-strength materials. Primary workpiece material compatibility includes steel, stainless steel, cast iron, super alloys, and titanium. The 3\/8-inch shank diameter fits standard ER and side-lock toolholders common on vertical machining centers and CNC mills. With a 2.5-inch overall length, it offers adequate reach for moderate-depth tapered features without sacrificing stiffness.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e15-degree taper angle per side (30-degree included angle) for accurate tapered wall geometry\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide construction for superior hardness and edge retention\u003c\/li\u003e\n  \u003cli\u003eThree right-hand helical flutes for balanced cutting and chip removal\u003c\/li\u003e\n  \u003cli\u003eSmall end diameter of 0.1250 inches for fine tapered slot entry\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for use with or without coolant on compatible materials\u003c\/li\u003e\n  \u003cli\u003eNon-centercutting design  -  requires a pre-drilled or pre-milled entry point\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on steel, stainless steel, cast iron, super alloys, and titanium workpieces.

Secure the 3\/8-inch shank in a clean, properly sized collet or toolholder and verify runout before cutting. This tool is not centercutting  -  always begin in a pre-machined pocket or use a plunge-capable tool to establish the entry point before engaging the tapered end mill. Follow machine manufacturer guidelines for spindle speed and feed rate based on workpiece material and depth of cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSmall End Diameter\u003c\/strong\u003e: 0.1250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLarge End Diameter\u003c\/strong\u003e: 0.3750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTaper Angle Per Side\u003c\/strong\u003e: 15 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.4670 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3750 inches\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: Helical\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: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Micrograin Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 15 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Super Alloys, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 69\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.45 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: INTERNAL TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 69-4060\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"INTERNAL TOOL","offers":[{"title":"Default Title","offer_id":67909752652082,"sku":"69-4060","price":131.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c9d5d93b2f6df132f401d85d60718b89_b94d2f76-cf63-416d-a4a2-fd5ea5967d3d.jpg?v=1791191273","url":"https:\/\/voomisupply.com\/products\/internal-tool-69-4060-tapered-end-mill-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
