With a 0.04-inch cutting diameter and four flutes, it is built for fine-detail work where tight tolerances and clean finishes matter. The AlTiN (aluminum titanium nitride) coating extends tool life in high-heat cutting environments by reducing friction and improving wear resistance. At 1.5 inches overall length with a 0.12-inch length of cut, this is a small-diameter tool suited for CNC machining centers running hardened steels, stainless, and high-temp alloys. Micrograin carbide substrate supports the edge integrity needed at this diameter range.\u003c\/p\u003e\u003cp\u003eThis end mill is used in CNC milling applications where small-feature work is required, including slots, pockets, and profiling on ferrous and non-ferrous materials. The 30-degree helix angle promotes smooth chip evacuation in right-hand cutting and right-hand flute configurations. The extended reach geometry and 0.36-inch reach length allow access into deeper features without excessive tool deflection. Typical users include CNC machinists, tool and die shops, and precision machine shops running production or prototype work on VMCs or HMCs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.04-inch cutting diameter with micrograin solid carbide substrate for edge stability at small diameters\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for improved heat resistance and extended tool life in ferrous machining\u003c\/li\u003e\n\u003cli\u003e4-flute spiral configuration with 30-degree helix angle for efficient chip flow\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows plunge entry without a pre-drilled start hole\u003c\/li\u003e\n\u003cli\u003eExtended reach with 0.36-inch reach length for accessing deeper features\u003c\/li\u003e\n\u003cli\u003eMill diameter tolerance of +0.0000\/-0.0010 inches for consistent fit in tight-tolerance work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC milling machines accepting a 0.125-inch round shank.

Ensure the spindle and tool holder are fully de-energized and at rest before loading or changing tooling. Verify shank seating depth and runout with a dial indicator before beginning a cut, as runout at this diameter range directly affects surface finish and tool life. Follow machine manufacturer guidelines for feed rate, spindle speed, and depth of cut when programming for this diameter.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.04 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.36 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 (Micrograin)\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000\/-0.0010 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001\/-0.0003 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 14899833\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51735841898802,"sku":"14899833","price":53.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5b82f5875115947985c987bb61ba9a2d.jpg?v=1788774479","url":"https:\/\/voomisupply.com\/products\/accupro-14899833-square-end-mill-0-04-in-4-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
