With a 0.0400-inch cutting diameter, 4-flute geometry, and a 30-degree helix angle, this tool delivers both roughing and finishing capability in a single pass. The stub flute design paired with an extended long-reach configuration — 2.5 inches overall length with a 0.1250-inch straight-cylindrical shank — makes it well suited for deep-reach work in confined pockets and contoured surfaces. A licensed machinist or CNC tooling professional installs and qualifies this tool in a precision collet or end mill holder.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use on steel, stainless steel, cast iron, and non-ferrous metals, covering ISO material codes P, M, K, and N. Its miniature footprint and long-reach stub-flute configuration make it a strong fit for CNC milling centers running detailed 3D contour work, die and mold finishing, and micro-feature machining where tool clearance in deep cavities is a priority. Single-end construction keeps the tool simple and consistent for high-repeatability production runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.0400-inch ball end cutting diameter with a 0.0200-inch nose radius for fine contour work\u003c\/li\u003e\n  \u003cli\u003e4-flute spiral geometry supports both roughing and finishing material removal\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle balances chip evacuation and cutting stability in ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eExtended long-reach design with 0.2030-inch reach length and 0.1430-inch neck length for deep-pocket access\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated solid carbide construction — no coating to flake or delaminate in precision cuts\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction; straight-cylindrical shank fits standard collet toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style miniature ball end mill for CNC machining centers and manual mills equipped with 1\/8-inch collet or end mill holder tooling.

Secure the 0.1250-inch straight-cylindrical shank in a precision collet or shrink-fit holder rated for the intended spindle speed and runout tolerance — miniature-diameter tools are particularly sensitive to runout, which can cause premature breakage. Confirm tool projection and reach clearance before initiating the program. Never exceed the manufacturer-recommended feed and speed parameters for the workpiece material and depth of cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.0400 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0005 \/ -0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.0200 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 0.0600 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.2030 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.1430 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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting 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 \/ Finish\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Miniature End Mills - Ball - Long Reach, Stub Flute\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.03 inches L x 0.32 inches W x 0.32 inches H\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: 803140\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51732623327538,"sku":"803140","price":80.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1e4ff98ba6be0b1540b7890f100b3662.jpg?v=1788745132","url":"https:\/\/voomisupply.com\/products\/harvey-tool-803140-ball-end-mill-0-04in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
