Built with a 3 mm cutting diameter, a 0.1 mm corner radius, and a variable helix geometry, this single-end tool reduces chatter and improves surface finish across both roughing and finishing passes. The TiB2 (titanium diboride) PVD coating provides excellent lubricity and hardness, making it particularly effective when cutting aluminum alloys. Three flutes with a right-hand cutting direction and spiral flute form balance chip evacuation with tool rigidity. The 4 mm straight-cylindrical shank is tolerance-rated h6 for use in high-precision toolholders.\u003c\/p\u003e\u003cp\u003eThis end mill is engineered for use in CNC milling operations across a broad range of workpiece materials including aluminum, cast iron, steel, stainless steel, wood, and composites. It belongs to the Variable Helix End Mills for Aluminum Alloys - Corner Radius series, making it well suited for shops running aluminum parts where controlled chip flow and edge quality are priorities. The center-cutting design allows plunge entry, and the regular-length flute with 9 mm length of cut supports slotting, profiling, and pocket milling in production or prototype environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eVariable helix geometry reduces harmonic vibration and chatter during cuts\u003c\/li\u003e\n\u003cli\u003eTiB2 PVD coating improves wear resistance and reduces built-up edge in aluminum and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable — supports direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003e3 flutes with right-hand spiral and right-hand cut for standard CNC milling setups\u003c\/li\u003e\n\u003cli\u003e0.1 mm corner radius extends tool life and improves corner finish versus square end mills\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank with h6 tolerance fits high-precision collet and hydraulic toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with high-precision toolholders.

Secure the shank in a high-precision collet, hydraulic, or shrink-fit toolholder to the toolholder manufacturer's specified clamping torque — do not use set-screw style holders that may damage the h6 shank tolerance. Verify runout at the cutting edge before production use. Ensure spindle speed and feed rate are set per the material-specific parameters for the workpiece material — never run this tool at settings intended for a different tool diameter or coating type.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3 mm (0.1181 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.1 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 9 mm (0.3543 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 50 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\u003eSingle or Double End\u003c\/strong\u003e: Single\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\u003eFlute Type\u003c\/strong\u003e: Spiral\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: TiB2 (PVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: 0.00 \/ -0.02 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: +0.025 \/ -0.025 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.25 \/ -0.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\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\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Cast Iron, Steel, Stainless Steel, Wood, Composite\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 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: 973557-C8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51749116510514,"sku":"973557-C8","price":75.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/26f78dc1691e7b1fded74fb24858b664_ad389458-1db7-4ef8-8873-cf46c5050420.jpg?v=1788902261","url":"https:\/\/voomisupply.com\/products\/harvey-tool-973557-c8-corner-radius-end-mill-3mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
