It features an 11-degree taper angle per side, a 1\/16-inch small end diameter, and a 3-flute helical geometry. The AlTiN (aluminum titanium nitride) PVD coating delivers elevated heat resistance and extended tool life when cutting ferrous and exotic materials. The 1\/4-inch shank diameter and 2.5-inch overall length make it suited for CNC machining centers and manual mills requiring tight-tolerance tapered profiles. Machinists and toolroom professionals are the primary users of this end mill.\u003c\/p\u003e\u003cp\u003eThis tapered end mill is applied in mold-making, die work, and precision part machining where a tapered wall profile is required. With a 0.5-inch length of cut and a 15-degree helix angle, it handles slotting and profiling in steel, stainless steel, cast iron, super alloys, and titanium. It is not center-cutting, so it requires a pre-drilled or pre-milled entry point before plunging. Typical applications include engraving lead-ins, draft-angle milling, and tapered cavity work on CNC equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e11-degree taper angle per side (22-degree included angle) for accurate draft and tapered-wall profiles\u003c\/li\u003e\n\u003cli\u003eAlTiN PVD coating for high-heat resistance when cutting steel, stainless, cast iron, and titanium alloys\u003c\/li\u003e\n\u003cli\u003eSolid micrograin carbide substrate for rigidity and wear resistance in tough workpiece materials\u003c\/li\u003e\n\u003cli\u003e3-flute helical design balances chip evacuation and surface finish in ferrous materials\u003c\/li\u003e\n\u003cli\u003e1\/16-inch small end diameter with a tolerance of +0.0000 \/ -0.0030 inches for precision fitment\u003c\/li\u003e\n\u003cli\u003eNot center-cutting  -  requires pre-milled entry; eliminates plunge-entry misuse\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and manual mills accepting a 1\/4-inch straight shank.

Secure the 1\/4-inch shank in a properly sized collet or end mill holder and verify runout before cutting. Because this tool is not center-cutting, always establish an entry point with a center-cutting tool before engaging the tapered end mill. Follow the machine manufacturer and tooling supplier guidelines for speeds and feeds appropriate to the 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 (0.0620 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLarge End Diameter\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inches (0.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/2 inches (0.5000 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\u003eTaper Angle Per Side\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 22 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: 15 degrees\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\u003eFlute Type\u003c\/strong\u003e: Helical\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\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Classification\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\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\u003eSmall End Diameter Tolerance\u003c\/strong\u003e: +0.0000 \/ -0.0030 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Super Alloys and 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: 0.4 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: INTERNAL TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 69-1105-C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"INTERNAL TOOL","offers":[{"title":"Default Title","offer_id":67907368026418,"sku":"69-1105-C","price":87.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c9d5d93b2f6df132f401d85d60718b89.jpg?v=1791178569","url":"https:\/\/voomisupply.com\/products\/internal-tool-69-1105-c-tapered-end-mill-altin-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
