Built from solid carbide and coated with AlTiN (aluminum titanium nitride), it delivers hardness and heat resistance suited for cutting ferrous alloys, hardened steels, and abrasive materials. The 4-flute design with a 30-degree helix angle promotes chip evacuation and surface finish quality at small scales. With a cutter diameter of 0.031 inches and a length of cut of 0.093 inches, this tool is built for micro-milling applications where accuracy and tool rigidity are non-negotiable. It is installed and run by machinists and CNC operators working in precision manufacturing environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for precision contouring, slotting, and profiling operations in CNC machining centers handling small-feature work. Its centercutting capability allows plunge entry, adding flexibility in complex toolpath strategies. The 0.125-inch shank diameter accommodates standard miniature toolholders, and the 1.5-inch overall length keeps overhang minimal for improved rigidity. Typical applications include mold and die work, aerospace component machining, and medical device manufacturing where tight tolerances on small features are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating provides thermal resistance and extended tool life in ferrous and hardened stock\u003c\/li\u003e\n  \u003cli\u003e4-flute geometry with 30-degree helix angle for balanced chip load and surface finish\u003c\/li\u003e\n  \u003cli\u003eCentercutting design enables direct plunge entry without pre-drilled pilot holes\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute configuration for standard CNC spindle operation\u003c\/li\u003e\n  \u003cli\u003eMiniature 0.031-inch diameter for micro-feature and fine-detail milling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and high-speed spindles accepting a 0.125-inch shank diameter.

Ensure the spindle is fully stopped and the machine is in a safe state before loading or unloading. Use a properly sized collet or toolholder rated for a 0.125-inch shank to prevent runout, which is especially critical at this diameter. Handle miniature carbide end mills with care to avoid chipping the cutting edges prior to use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Diameter\u003c\/strong\u003e: 0.031 inches (1\/32 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.093 inches (3\/32 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches (1-1\/2 inch)\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 (Aluminum Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\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: HARVEY TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 73031-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51731068682546,"sku":"73031-C3","price":51.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b439e4d9750d2d519b94c7aaf8826d59_c7dddc04-d22c-44a5-8be1-20b42e08538c.jpg?v=1788726558","url":"https:\/\/voomisupply.com\/products\/harvey-tool-73031-c3-square-end-mill-1-32-inch-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
