Built from solid carbide and finished with an amorphous diamond coating, it delivers wear resistance and edge retention in demanding materials. The 2-flute configuration provides efficient chip evacuation in confined cuts. With a cutting diameter of 0.031 inches and a 3\/32-inch length of cut, this tool is suited for micro-slot milling, profiling, and detail work where larger tooling cannot reach. It is installed and run by machinists and tool-and-die professionals using CNC mills and high-speed machining centers.\u003c\/p\u003e\n\u003cp\u003eThis end mill fits applications requiring extremely fine detail in metals, composites, and engineered plastics. The 30-degree helix angle balances cutting forces and chip flow at small diameters. Centercutting geometry allows plunge entry, adding flexibility in programming. The 1\/8-inch shank diameter is a common size for small-diameter collet systems on CNC machining centers, making this a practical drop-in for micro-milling operations in toolrooms, moldmaking shops, and precision manufacturing environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and edge retention at small diameters\u003c\/li\u003e\n  \u003cli\u003eAmorphous diamond finish reduces friction and extends tool life in abrasive materials\u003c\/li\u003e\n  \u003cli\u003e2-flute design promotes chip clearance in narrow slots and deep pockets\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle balances axial cutting forces for stable micro-milling\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry permits direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute — standard configuration for conventional CNC setups\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 mills equipped with 1\/8-inch collet holders or ER-series collet systems.

Ensure the collet and collet nut are clean and free of debris before seating the 1\/8-inch shank, as runout at this diameter significantly affects tool life and surface finish. Always verify spindle speed and feed rate are appropriate for the 0.031-inch diameter before engaging the cut. Do not exceed the rated length of cut, and inspect the tool under magnification before reuse to detect edge chipping invisible to the naked eye.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/32 inch (0.031 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/32 inch (0.093 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.125 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Amorphous Diamond\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 72031-C4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51727535145266,"sku":"72031-C4","price":65.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9184774782667b791afe87d92ba49005_d14ee335-46e0-4f87-82ef-be2fa698b820.jpg?v=1788678983","url":"https:\/\/voomisupply.com\/products\/harvey-tool-72031-c4-square-end-mill-1-32-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
