Built from micrograin solid carbide and coated with AlTiN, it delivers heat resistance and wear life needed when cutting hard ferrous alloys and stainless steels at elevated speeds. The cutter measures 0.6 mm in diameter with a 0.05 mm corner radius, a 0.6 mm length of cut, and a 50 mm overall length. The 4 mm shank diameter and 12 mm reach length make it well suited for tight-clearance work where extended reach is required. Centercutting geometry allows direct plunge entry without a pre-drilled pilot hole.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for CNC machining centers, micro-milling operations, and die and mold work where fine detail and tight tolerances are critical. The right-hand spiral flute design with a 30-degree helix angle promotes efficient chip evacuation in slotting, profiling, and ramp milling. It is a strong fit for tool and die shops, aerospace component machining, and medical device manufacturing where small-diameter, high-precision cutters are routine. The extended reach configuration allows access to deep cavities and stepped pockets not reachable with standard-reach tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.05 mm corner radius protects edge integrity and reduces stress concentration at part corners\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate provides rigidity and dimensional stability at small diameters\u003c\/li\u003e\n\u003cli\u003eAlTiN coating improves oxidation resistance and extends tool life in high-temperature cutting conditions\u003c\/li\u003e\n\u003cli\u003eCentercutting design supports direct plunge milling without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle with right-hand spiral fluting promotes clean chip evacuation\u003c\/li\u003e\n\u003cli\u003eExtended reach with 12 mm reach length for deep-cavity and stepped-pocket access\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a drop-in replacement-style cutter for CNC machining centers and manual mills equipped with a 4 mm collet or matching tool holder accepting a 4 mm shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle and collet are fully powered down and locked out before inserting or removing the tool. Use a collet sized to the 4 mm shank diameter and verify runout with a dial indicator before commencing cuts. At this diameter, excessive overhang beyond the specified reach length significantly increases deflection risk and should be avoided.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.6 mm (0.0236 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.05 mm (0.0020 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.6 mm (0.1181 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 50 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 12 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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\u003eExtended Reach\u003c\/strong\u003e: Yes\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000200 to -0.000800 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0.00100 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.75 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: 12177320\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51751694205234,"sku":"12177320","price":79.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6e5c2a1d8ee287ab1c46d5959e7d087f.jpg?v=1788924112","url":"https:\/\/voomisupply.com\/products\/accupro-12177320-corner-radius-end-mill-0-6-mm-2-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
