It carries a 0.093-inch cutting diameter with a 0.03-inch corner radius and runs three right-hand helical flutes at a 30-degree helix angle. The extended-reach design places the cutting zone at the end of a long, slim neck, enabling access to deep pockets and slots that standard-length tools cannot reach. At 2.5 inches overall length with a 0.125-inch straight shank, this single-end mill is center-cutting and suited for both roughing and finishing passes in one tool. It ships uncoated and is part of Harvey Tool's Miniature End Mills Long Reach Stub Flute series.\u003c\/p\u003e\u003cp\u003eThis end mill is engineered for precision machining operations where a small-diameter, long-reach tool is required. Typical applications include deep pocket milling, profile work, and corner radius generation on dies, molds, and tight-geometry workpiece features. The stub flute length of 0.139 inches limits deflection at the cutting edge while the 0.75-inch reach length provides clearance from the shank. It is appropriate for use in CNC machining centers and manual mills equipped with a compatible toolholder. Primary workpiece materials include steel, stainless steel, cast iron, aluminum, composites, and wood.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.03-inch corner radius with a tolerance of plus 0.001 to minus 0.001 inch for consistent edge geometry\u003c\/li\u003e\n\u003cli\u003e0.093-inch cutting diameter held to plus 0.0005 to minus 0.0005 inch tolerance\u003c\/li\u003e\n\u003cli\u003eExtended reach of 0.75 inches enables deep pocket access with a short 0.139-inch length of cut\u003c\/li\u003e\n\u003cli\u003eThree right-hand flutes with 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction delivers rigidity and wear resistance across ferrous and non-ferrous materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard straight-shank toolholders accepting a 0.125-inch shank diameter.

Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the 0.125-inch shank fully into a clean, properly sized collet or toolholder and torque the retention mechanism per the toolholder manufacturer's specification. Inspect the corner radius and cutting edges for chips or damage before each use, as carbide is brittle and sensitive to improper handling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.093 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\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut (Flute Length)\u003c\/strong\u003e: 0.139 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\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.75 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 Type\u003c\/strong\u003e: Corner Radius\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\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated (Bright)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single End\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: plus 0.0005 to minus 0.0005 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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Aluminum, Non-Ferrous Metal, Composite, Wood\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 42393\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51737248137522,"sku":"42393","price":79.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6aa536101e5e90c004fe39f0183f1c97_32b2ad74-9ff3-4b4e-b924-29ed655faf0b.jpg?v=1788786087","url":"https:\/\/voomisupply.com\/products\/harvey-tool-42393-corner-radius-end-mill-0-093-in-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
