With a cutter diameter of 3\/32 inches (0.0930 inches decimal) and a 9\/64-inch length of cut, this single-end tool delivers controlled material removal in tight geometries. The 42-degree variable helix and three-flute design reduce chatter and improve chip evacuation. A Titanium Diboride (TiB2) coating increases surface hardness and reduces friction, extending tool life in abrasive or difficult-to-machine materials. The downcut flute configuration pushes chips downward, making it well suited for applications where surface finish and edge quality on the top face of the workpiece are critical.\u003c\/p\u003e\u003cp\u003eThis end mill is used in CNC milling operations across industries requiring fine detail work, including moldmaking, aerospace component machining, and precision part production. The 1\/8-inch shank diameter fits standard collet systems on vertical machining centers and CNC routers. The 1-1\/2-inch overall length provides sufficient reach for most shallow-pocket and profiling operations without sacrificing rigidity. Machinists working with composites, hardwoods, plastics, and non-ferrous metals will find the downcut geometry especially useful for minimizing delamination and surface tearout.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/32-inch cutter diameter with 9\/64-inch length of cut for fine detail milling\u003c\/li\u003e\n\u003cli\u003e42-degree variable helix reduces vibration and improves surface finish\u003c\/li\u003e\n\u003cli\u003eThree-flute downcut design promotes top-surface finish quality and controlled chip flow\u003c\/li\u003e\n\u003cli\u003eTiB2 (Titanium Diboride) coating for increased hardness and reduced tool wear\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and heat resistance\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with right-hand cutting direction\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and routers equipped with standard 1\/8-inch collets or tool holders.

Ensure the spindle is fully powered down and the machine is locked out before changing tooling. Seat the 1\/8-inch shank fully into the collet and torque the collet nut according to the collet manufacturer's specifications. Verify runout with a dial indicator before beginning a production run to avoid premature tool wear or workpiece damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Diameter\u003c\/strong\u003e: 3\/32 inches (0.0930 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 9\/64 inches (0.1400 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-1\/2 inches (1.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inches (0.1250 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: 42 degrees variable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Downcut\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Titanium Diboride (TiB2)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 858593-C8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51753207103794,"sku":"858593-C8","price":75.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bef6cb198ab5673d704f084edb9d3cc2_583f5b17-c4f2-437c-ac5b-60cc307d6324.jpg?v=1788933881","url":"https:\/\/voomisupply.com\/products\/harvey-tool-858593-c8-square-end-mill-3-32-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
