It features a 0.8 mm mill diameter with a 0.1 mm corner radius and a 2-flute, right-hand spiral configuration with a 30-degree helix angle. The single-end, centercutting design allows plunging and slotting in tight geometries. Built from micrograin solid carbide with a bright uncoated finish, this tool is suited for machinists and tool and die professionals working in high-precision, small-feature applications where dimensional accuracy and edge integrity are critical.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in CNC machining centers and manual mills where fine detail work, small-pocket milling, or contour finishing is required. The extended reach configuration, with a 5 mm reach length and 4 mm shank diameter, allows access to features with restricted clearance. The 0.8 mm length of cut is optimized for shallow passes in hardened or abrasive materials where micrograin carbide substrates provide wear resistance and edge stability.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.8 mm mill diameter with 0.1 mm corner radius for precise edge blending and reduced stress concentration\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide construction for superior hardness and wear resistance at small diameters\u003c\/li\u003e\n  \u003cli\u003e2-flute, right-hand cut, right-hand spiral design with 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting capability allows direct plunge entry into workpiece material\u003c\/li\u003e\n  \u003cli\u003eExtended reach with 5 mm reach length for access to recessed or deep-pocket features\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for a broad range of materials without coating compatibility concerns\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use end mill for CNC machining centers and manual mills accepting a 4 mm straight shank.

Ensure the spindle is fully stopped and locked before inserting or removing the tool from the holder. Verify collet size matches the 4 mm shank diameter and that runout is minimized to protect the tool at this diameter. Avoid excessive overhang beyond the specified reach length, as small-diameter carbide tools are brittle and susceptible to breakage under lateral loading.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.8 mm (0.0315 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.1 mm (0.0039 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.8 mm (0.1575 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: 5 mm\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: Micrograin 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\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\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eSingle or Double End\u003c\/strong\u003e: Single\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\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 12177321\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51744642269490,"sku":"12177321","price":59.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/19c3ba306d241c82c1593a7255d1755b.jpg?v=1788859360","url":"https:\/\/voomisupply.com\/products\/accupro-12177321-corner-radius-end-mill-0-8-mm-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
