It carries a 0.025 inch mill diameter, a 0.038 inch length of cut, and a 2.5 inch overall length with extended reach geometry. The AlTiN PVD coating provides thermal and oxidation resistance suited to cutting steel, stainless steel, cast iron, and hard alloys at elevated temperatures. The variable helix design reduces harmonic chatter during both roughing and finishing passes. Three flutes, right-hand cutting and flute direction, and centercutting capability make this tool suitable for plunge entry and full-contour work. Licensed machinists and CNC operators working in aerospace, medical, mold, and precision job shop environments are the primary users.\u003c\/p\u003e\u003cp\u003eThis end mill targets applications where tight corner geometry and extended reach are required in hard and high-temp workpiece materials. The stub flute and long reach configuration allows access into deeper pockets and narrow profiles without sacrificing rigidity at this diameter. Workpiece materials listed by the manufacturer include steel, stainless steel, cast iron, and hard alloy. The 0.004 inch corner radius and 0.125 inch straight-cylindrical shank are dimensioned for use with high-precision toolholders. It is a single-end tool intended for CNC machining centers running right-hand spindle rotation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eVariable helix geometry reduces chatter during high-temp alloy machining\u003c\/li\u003e\n\u003cli\u003eAlTiN PVD coating rated for thermal resistance in steel, stainless, cast iron, and hard alloy\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge and ramp entry\u003c\/li\u003e\n\u003cli\u003eExtended reach with stub flute for deep pocket and narrow profile access\u003c\/li\u003e\n\u003cli\u003e0.004 inch corner radius with tolerance of plus or minus 0.001 inch\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity at 0.025 inch diameter\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with high-precision toolholders.

Confirm runout at the toolholder before use, as diameter tolerances at this scale are critical. Power down the spindle and release all stored energy before tool changes. Do not exceed manufacturer-recommended speeds and feeds for the specific workpiece material and coating type.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.025 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.004 inches (0.10 mm)\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\u003c\/strong\u003e: 0.038 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\u003eReach Length\u003c\/strong\u003e: 0.203 inches (13\/64 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: plus 0.0005 \/ minus 0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: plus 0.001 \/ minus 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: plus 0.010 \/ minus 0.000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 34 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Type\u003c\/strong\u003e: Variable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Extended Reach\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, Hard Alloy\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\u003eWeight\u003c\/strong\u003e: 1 pound\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: 54825-C6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51735299883314,"sku":"54825-C6","price":109.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8b89ba11155e75f3321896e0e47122c1_7452fb01-0884-47f1-8539-a892e540d18c.jpg?v=1788771601","url":"https:\/\/voomisupply.com\/products\/harvey-tool-54825-c6-corner-radius-end-mill-altin-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
