With a 0.109-inch cutting diameter and a 0.010-inch corner radius, it delivers a controlled edge break on part features without sacrificing dimensional accuracy. The four-flute, right-hand helical design at a 30-degree helix angle promotes efficient chip evacuation and stable cutting action. An AlTiN (aluminum titanium nitride) PVD coating improves heat resistance and extends tool life when machining ferrous and hard materials. This tool is single-end, centercutting, and suited for both roughing and finishing passes in tight geometries.\u003c\/p\u003e\u003cp\u003eThis end mill is built for precision machining applications where small-diameter tooling is required. It fits standard straight-shank toolholders with a 1\/8-inch (0.125-inch) shank diameter. Typical applications include die and mold work, medical component machining, aerospace detail parts, and other operations involving steel, stainless steel, cast iron, non-ferrous metals, and composite materials. The stub and standard series designation means it is optimized for rigidity in short-reach, high-accuracy cuts where tool deflection must be minimized.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.010-inch corner radius with a tolerance of plus or minus 0.001 inches for precise edge geometry\u003c\/li\u003e\n\u003cli\u003eAlTiN PVD coating for elevated heat resistance in ferrous and hard-material applications\u003c\/li\u003e\n\u003cli\u003eFour right-hand helical flutes at 30-degree helix angle for smooth chip flow\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows plunge and ramp entry moves\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and wear resistance in miniature tooling applications\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank compatible with standard collet-style toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard straight-shank collet toolholders accepting a 1\/8-inch shank.

Ensure the toolholder is clean and free of chips or debris before seating the shank, and torque collet nuts to the toolholder manufacturer specification. Verify spindle runout is within acceptable limits before beginning a cut, as excessive runout will accelerate wear and compromise corner radius accuracy on a tool of this diameter. Follow machine guarding and PPE requirements appropriate to the milling operation.\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: plus 0.0005 to minus 0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.010 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: plus 0.001 to minus 0.001 inches\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: 0.327 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 to minus 0.000 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\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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: Helical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN (PVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\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\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: 75802-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51728517169458,"sku":"75802-C3","price":60.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fe9dfb4bd777927aee3a1c807088ea9b_aa9b35a2-9ec8-4ae6-9dcb-cc1435a45dc0.jpg?v=1788692551","url":"https:\/\/voomisupply.com\/products\/harvey-tool-75802-c3-corner-radius-end-mill-0-109in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
