With a 1 mm cutting diameter and a 3-flute geometry, this end mill delivers efficient chip evacuation and a clean finish in hard and abrasive materials. The AlTiN (aluminum titanium nitride) coating increases surface hardness and thermal resistance, extending tool life in high-speed dry or semi-dry cutting conditions. The 30-degree helix angle balances cutting forces and surface finish quality. Right-hand cutting and right-hand flute direction are standard. This tool is intended for use by machinists and tooling professionals working on CNC milling centers.\u003c\/p\u003e\u003cp\u003eThe 888439-C3 is suited for precision profiling, slotting, and contouring operations on ferrous and non-ferrous materials where tight tolerances and fine surface finishes are required. Its sub-2 mm diameter makes it appropriate for micro-milling work, mold and die detail work, and small-feature machining on CNC vertical or horizontal machining centers. The single-end configuration and solid carbide construction make it a standard tooling choice in production and prototype environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1 mm cutting diameter for micro-milling and fine-feature work\u003c\/li\u003e\n\u003cli\u003e3-flute design improves chip flow and finish quality over 2-flute alternatives\u003c\/li\u003e\n\u003cli\u003eAlTiN coating provides elevated heat and wear resistance for extended tool life\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle balances cutting forces and surface quality\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard CNC spindle compatibility\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction delivers rigidity and dimensional stability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers accepting a 0.125 inch (1\/8 inch) shank diameter collet or end mill holder.

Ensure the machine spindle is fully stopped and the tool-change mode is active before inserting or removing the end mill. Use a precision collet or shrink-fit holder rated for the 0.125 inch shank diameter to maintain runout within acceptable tolerances. Avoid side-loading or over-projecting the tool beyond the recommended length of cut to prevent deflection or breakage in this sub-2 mm diameter range.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 mm (0.0390 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/32 inches (0.156 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inches (0.125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches (2.5 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\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\u003eCentercutting\u003c\/strong\u003e: No\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: 888439-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51732420722994,"sku":"888439-C3","price":69.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4e8812d2b2470bfaa489e415e80bcb36_5d8924c1-3936-4081-943f-50d0e10c146a.jpg?v=1788742609","url":"https:\/\/voomisupply.com\/products\/harvey-tool-888439-c3-square-end-mill-1mm-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
