With a 0.04-inch cutting diameter and a 13\/64-inch (0.203-inch) length of cut, this long-flute end mill handles fine detail work where standard-reach tools cannot reach. The AlTiN coating provides thermal resistance and hardness, making it well-suited for dry or semi-dry cutting in demanding materials. Four spiral flutes with a 30-degree helix angle promote efficient chip evacuation and a smooth finish. Right-hand cut and right-hand flute geometry are standard for conventional CNC milling setups. Centercutting geometry allows direct plunge entry. The 1\/8-inch shank and 2.5-inch overall length fit common ER and precision collet systems.\u003c\/p\u003e\n\u003cp\u003eThis end mill is rated for use in steel, stainless steel, cast iron, aluminum and non-ferrous materials, and CFRP composites. It belongs to the Harvey Tool Miniature End Mills - Square - Long Flute series, intended for high-precision work in aerospace, medical, mold and die, and electronics machining where small-diameter, long-reach tooling is required. It is a single-end tool with no chipbreaker and no coolant-through capability, best suited for light radial cuts at elevated spindle speeds typical of miniature toolpaths.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.04-inch cutting diameter with 0.203-inch length of cut for fine detail and slot milling\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance at small diameters\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating for heat resistance in ferrous and high-hardness materials\u003c\/li\u003e\n  \u003cli\u003e4-flute spiral geometry with 30-degree helix for smooth cutting action and chip flow\u003c\/li\u003e\n  \u003cli\u003eCentercutting design permits direct plunge entry\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute  -  compatible with standard CNC spindle rotation\u003c\/li\u003e\n  \u003cli\u003eLong-flute series provides extended reach relative to standard miniature end mill configurations\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 1\/8-inch shank via ER collet, precision collet chuck, or equivalent toolholding system.

Seat the 1\/8-inch shank fully and evenly in a clean, undamaged collet to minimize runout, which is critical at this diameter. At 0.04 inches, deflection and runout tolerances are extremely tight  -  inspect collet condition and holder concentricity before use. Speeds, feeds, and depth-of-cut parameters should be set per the manufacturer's published miniature end mill guidelines for the specific workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.04 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 13\/64 inch (0.203 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: 2.5 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\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\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Miniature End Mills - Square - Long Flute\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 834140-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51743972131122,"sku":"834140-C3","price":72.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4e8812d2b2470bfaa489e415e80bcb36_568a9c26-6c0e-4704-916c-d64047ef0adc.jpg?v=1788852198","url":"https:\/\/voomisupply.com\/products\/harvey-tool-834140-c3-square-end-mill-0-04-in-4-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
