Built from solid carbide with an AlTiN (aluminum titanium nitride) PVD coating, it handles steel, stainless steel, cast iron, and non-ferrous metals. The 0.5 mm cutting diameter pairs with a 0.0050-inch corner radius to produce clean, repeatable edge breaks and floor transitions. With a 30-degree helix angle and 3-flute geometry, it supports both roughing and finishing passes. The extended reach design — 2.5 inches overall length on a 1\/8-inch shank — gives access to recessed features and deep pockets where standard-length tools cannot reach.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for precision CNC milling operations on machining centers and mill-turn platforms. The stub flute configuration keeps the cutting zone rigid while the long-reach shank clears workholding and fixture obstructions. Typical applications include micro-mold detail work, medical component machining, and fine-feature aerospace part production where consistent corner geometry and surface finish are critical. It is right-hand cut, right-hand flute, single-end, and centercutting, making it capable of plunge entry as well as peripheral and face milling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating extends tool life in steel and stainless steel cutting\u003c\/li\u003e\n  \u003cli\u003e0.0050-inch corner radius with tolerance of plus or minus 0.0010 inches for consistent edge geometry\u003c\/li\u003e\n  \u003cli\u003eExtended reach design with 1\/8-inch straight-cylindrical shank for deep-feature access\u003c\/li\u003e\n  \u003cli\u003e3-flute spiral geometry supports both roughing and finishing in a single tool\u003c\/li\u003e\n  \u003cli\u003eCentercutting capability allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard CNC toolholders accepting a 1\/8-inch straight-cylindrical shank.

Ensure the toolholder collet or chuck is clean and properly torqued before use, and verify runout with a dial indicator prior to cutting. Confirm spindle speed and feed rate programming matches the tool diameter — at 0.5 mm, cutting parameters are extremely sensitive to programming errors. Never exceed the rated depth of cut or apply side loads beyond what the extended-reach geometry supports, as carbide is brittle and can fracture without warning under shock loading.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 mm (0.0200 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0050 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: plus or minus 0.0010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: plus or minus 0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.0300 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.1600 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\u003eOverall Length Tolerance\u003c\/strong\u003e: plus 0.0100 \/ minus 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1250 inches (1\/8 inches)\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 (PVD)\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eCoolant Through\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\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Composite\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Miniature End Mills - Corner Radius - Long Reach, Stub Flute\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: HARVEY TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 38320-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51728450453810,"sku":"38320-C3","price":102.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6aa536101e5e90c004fe39f0183f1c97_b9291edf-6d11-4e2f-8220-e5cd1dc8296f.jpg?v=1788691370","url":"https:\/\/voomisupply.com\/products\/harvey-tool-38320-c3-corner-radius-end-mill-0-5mm-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
