With a 0.085-inch cutting diameter and a 0.127-inch length of cut, this stub-length tool delivers tight-tolerance profiling and finishing passes in confined workspaces. The 4-flute, right-hand helical configuration with a 30-degree helix angle promotes efficient chip evacuation while maintaining surface finish quality. An AlTiN PVD coating increases surface hardness and oxidation resistance, extending tool life in steel, stainless steel, and cast iron applications. Licensed machinists and CNC programmers working in tool-and-die, mold making, and precision component manufacturing will find this end mill suited to demanding small-feature work.\u003c\/p\u003e\u003cp\u003eThis end mill is built for steel, stainless steel, and cast iron workpiece materials, covering material grades P, M, and K. Its stub length and 0.125-inch straight cylindrical shank make it a direct fit for standard 1\/8-inch collet toolholders on VMCs, HMCs, and CNC router setups. It is suited to both roughing and finishing operations on small part features, slots, and contoured surfaces where tool rigidity and minimal deflection are critical. Single-end construction allows for precise tool-length offset management in automated machining environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.085-inch ball end cutting diameter with a 0.0425-inch nose radius for accurate small-radius profiling\u003c\/li\u003e\n\u003cli\u003eAlTiN PVD coating for elevated hardness and heat resistance in steel and stainless steel cutting\u003c\/li\u003e\n\u003cli\u003e4-flute, right-hand helical design at 30 degrees for improved chip flow and surface finish\u003c\/li\u003e\n\u003cli\u003eStub length of cut at 0.127 inches provides enhanced rigidity and reduced deflection\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction delivers consistent dimensional accuracy throughout tool life\u003c\/li\u003e\n\u003cli\u003eCompatible with roughing and finishing operations across P, M, and K material grades\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in 1\/8-inch collet toolholders.

Ensure the machine spindle is fully stopped and the toolholder is clean and free of debris before seating the shank. Verify collet runout with a dial indicator before first use, as miniature-diameter tools are sensitive to runout-induced breakage. Follow the machine tool manufacturer and ANSI safety guidelines for tool clamping torque and minimum shank engagement depth.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.085 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.0425 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut (Reach)\u003c\/strong\u003e: 0.127 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN (PVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0005 \/ -0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 24685-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51734325952818,"sku":"24685-C3","price":57.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4554b3f94a5d0cb64c40eb2d2d45cdda_9250044d-bc97-4226-adfe-6aa08fc2a704.jpg?v=1788762515","url":"https:\/\/voomisupply.com\/products\/harvey-tool-24685-c3-ball-end-mill-0-085-in-4-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
