Built for the stub and standard series, it features a 0.109-inch mill diameter, a 0.005-inch corner radius, and an AlTiN (aluminum titanium nitride) PVD coating that extends tool life when cutting ferrous and hard materials. With 4 helical flutes in a right-hand cutting direction and a center-cutting geometry, this end mill handles both roughing and finishing passes. It is suited for machinists and tool-and-die professionals running CNC mills where tight tolerances and small-diameter tooling are required.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in applications requiring fine detail work and tight corner radii in a range of workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, and composites. Its short flute length and stub-profile geometry make it well suited for rigid setups with minimal tool overhang. The 1\/8-inch straight cylindrical shank fits standard collet toolholders commonly found in vertical machining centers and CNC routers handling miniature or precision work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.005-inch corner radius with a tolerance of +0.0010 to -0.0010 inches for controlled edge geometry\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating for heat resistance and extended tool life in ferrous and hard materials\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in precision applications\u003c\/li\u003e\n  \u003cli\u003e4 right-hand helical flutes with center-cutting capability for plunge and contour operations\u003c\/li\u003e\n  \u003cli\u003eShort flute length profile reduces deflection in tight or deep-pocket setups\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard straight-bore collet toolholders via 1\/8-inch cylindrical shank\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard collet-style toolholders accepting a 1\/8-inch straight cylindrical shank.

Ensure the machine spindle is fully stopped and the toolholder is clean and free of debris before seating the shank. Torque collet nuts to toolholder manufacturer specifications. Verify runout at the tool tip with a dial indicator before cutting, especially critical at this diameter range where small runout values have a proportionally large effect on tool life and part accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 0.005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 0.164 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\u003eMaterial\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Short\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0005 to -0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: +0.0010 to -0.0010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.0100 to -0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 941402-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51743918686514,"sku":"941402-C3","price":60.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fe9dfb4bd777927aee3a1c807088ea9b_da018f80-80d9-41ab-9f16-581b4e96e200.jpg?v=1788851268","url":"https:\/\/voomisupply.com\/products\/harvey-tool-941402-c3-corner-radius-end-mill-0-109-in-4-fl","provider":"Voomi Supply","version":"1.0","type":"link"}
