With a 5\/64 inch (0.078 inch decimal) cutting diameter and a 0.117 inch length of cut, this tool is built for tight-tolerance work where dimensional accuracy matters. The AlTiN coating improves heat resistance and extends tool life in ferrous and hardened materials. Four right-hand flutes with a 30-degree helix angle provide efficient chip evacuation and a clean finish on the workpiece. This end mill is installed and operated by machinists in CNC and manual milling environments.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for small-feature milling in steel, stainless steel, and other hard alloys where a fine-diameter tool is required. The extended reach design, with a 0.625 inch reach length, allows access to deeper pockets and slots without interference from the shank. It is a single-end tool intended for right-hand cutting direction. Typical applications include profiling, slotting, and finishing passes on close-tolerance features in production and prototype machining environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiN coating for elevated heat resistance and extended tool life in hard materials\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and dimensional stability\u003c\/li\u003e\n\u003cli\u003e4 right-hand flutes with 30-degree helix for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eExtended reach design with 0.625 inch reach length for deeper pocket access\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for standard CNC spindle compatibility\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration for straightforward toolholder setup\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard-fitment square end mill for CNC machining centers and manual mills using a 1\/8 inch shank collet or toolholder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop-standard toolholder torque procedures. Ensure the spindle is fully stopped and locked out before changing tooling. Verify collet size matches the 1\/8 inch shank diameter before seating the tool. Do not exceed manufacturer-recommended feed and speed parameters for the workpiece material and coating type.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/64 inch (0.078 inches decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.117 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\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.125 inches decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.625 inches\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfiguration\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 874178-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51744666550578,"sku":"874178-C3","price":81.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/48693790ec4e97f05d5a09a1389fd32c_c46e639d-81fd-423f-923a-fb79ffacef0b.jpg?v=1788859766","url":"https:\/\/voomisupply.com\/products\/harvey-tool-874178-c3-square-end-mill-5-64-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
