Built from solid carbide and finished with an amorphous diamond (PVD diamond) coating, this tool delivers the hardness and edge retention required in demanding cutting environments. The 1\/32 inch (0.0310 inch) cutting diameter pairs with a 3\/32 inch (0.0930 inch) length of cut and a 30-degree helix angle, making it well-suited for light, controlled passes in hard and abrasive workpiece materials. Licensed machinists and toolroom technicians are the primary users of this type of miniature end mill.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in CNC machining centers and manual mills where miniature features, slots, or profiles require tight dimensional control. It is rated for use in steel, stainless steel, cast iron, aluminum and other non-ferrous metals, and CFRP (carbon fiber reinforced polymer) materials. The stub and standard flute geometry in the miniature series makes this tool appropriate for shallow-pocket and slot milling where rigidity is critical and deflection must be minimized. Right-hand cut and right-hand flute direction are standard for conventional spindle setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003eAmorphous diamond PVD coating extends tool life in abrasive and high-hardness workpieces\u003c\/li\u003e\n\u003cli\u003e4-flute design improves surface finish and material removal rate over 2-flute alternatives\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle balances cutting force and chip evacuation across multiple material types\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable, allowing plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with 1\/8 inch shank diameter for standard collet compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for use in steel, stainless steel, cast iron, aluminum and non-ferrous metals, and CFRP materials (material codes P, M, K, N, C).

Secure the 1\/8 inch shank in a matching precision collet or end mill holder; avoid side-loading or over-tightening that could fracture the carbide shank at this diameter. At 1\/32 inch cutting diameter, feed and speed parameters must be carefully calculated to avoid tool breakage — consult the manufacturer published speeds and feeds chart for this series. This tool is not designed for coolant-through delivery; direct flood or mist coolant at the cutting zone externally if coolant is used.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/32 inch (0.0310 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/32 inch (0.0930 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inch)\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Amorphous Diamond (PVD Diamond)\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\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\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Aluminum and Non-Ferrous, CFRP\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: 73031-C4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51730071093554,"sku":"73031-C4","price":65.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9184774782667b791afe87d92ba49005_c459d01c-f3c8-4211-bab1-d2610a9a2328.jpg?v=1788711209","url":"https:\/\/voomisupply.com\/products\/harvey-tool-73031-c4-square-end-mill-1-32-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
