It carries a 0.109 inch mill diameter, a 0.03 inch corner radius with a tolerance of plus or minus 0.001 inch, and an AlTiN (aluminum titanium nitride) PVD coating that extends tool life in high-heat cutting environments. With four helical flutes in a right-hand cutting direction and a center-cutting design, it handles both roughing and finishing passes in a single tool. Licensed machinists and CNC programmers working in tight-tolerance, small-feature applications will find this tool suited to their requirements.\u003c\/p\u003e\u003cp\u003eThis end mill fits into the Harvey Tool Miniature End Mills - Corner Radius - Stub and Standard series, targeting small-feature milling work on CNC machining centers and manual mills. It is appropriate for residential prototype shops, tool-and-die operations, and production facilities cutting steel, stainless steel, cast iron, composites, and non-ferrous materials. The stub-to-standard length configuration keeps deflection low when reaching into pockets or profiling edges with tight radii. The straight cylindrical shank seats directly into standard collets and toolholders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiN PVD coating for elevated heat resistance in ferrous and stainless steel cutting\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows plunge entry without a pre-drilled start hole\u003c\/li\u003e\n\u003cli\u003eFour helical flutes in right-hand direction for chip evacuation and smooth surface finish\u003c\/li\u003e\n\u003cli\u003eCorner radius tolerance held to plus or minus 0.001 inch for repeatable edge geometry\u003c\/li\u003e\n\u003cli\u003eMill diameter tolerance of plus or minus 0.0005 inch supports tight-tolerance feature work\u003c\/li\u003e\n\u003cli\u003eSingle-end, no chipbreaker configuration for straightforward finishing and light roughing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with standard collet-style toolholders and cylindrical-bore end mill holders accepting a 0.125 inch (1\/8 inch) shank diameter.

Ensure the spindle is fully stopped and the machine is in an e-stop or powered-down state before changing tooling. Seat the shank fully into the collet or toolholder to the recommended engagement depth before torquing the retention mechanism. Verify runout at the cutting diameter with a dial indicator before committing to a production cut, as runout directly affects corner radius accuracy and tool life.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.109 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.03 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: plus 0.001 inch to minus 0.001 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: plus 0.0005 inch to minus 0.0005 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.375 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\u003eOverall Length Tolerance\u003c\/strong\u003e: plus 0.010 inch to minus 0.000 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 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\u003eCenter Cutting\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\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\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: HARVEY TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 937602-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51750504661298,"sku":"937602-C3","price":60.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fe9dfb4bd777927aee3a1c807088ea9b_c700d2df-dd3d-4344-829d-a746fac17202.jpg?v=1788915961","url":"https:\/\/voomisupply.com\/products\/harvey-tool-937602-c3-corner-radius-end-mill-0-109in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
