With a 0.125 inch mill diameter and a 1.25 inch length of cut, this tool delivers extra-long flute reach in a miniature form factor. The variable helix geometry reduces chatter and improves surface finish during finishing passes. Three right-hand spiral flutes evacuate chips efficiently while maintaining rigidity in the cut. This tool is intended for use by machinists and tooling specialists working on CNC machining centers and manual mills requiring tight-tolerance profiling and contouring.\u003c\/p\u003e\n\u003cp\u003eThe 957308 is suited for finishing operations in hard materials, including steel, stainless steel, and cast iron. Its extra-long flute length makes it appropriate for deep-cavity milling, rib profiling, and contoured surface work where standard-length tooling cannot reach. The straight cylindrical shank with h6 tolerance ensures secure collet clamping in precision toolholders. The bright uncoated finish makes this tool a reliable choice when coating interactions with the workpiece material are a concern or when regrinding is anticipated.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eVariable helix design reduces harmonic vibration and chatter during finishing cuts\u003c\/li\u003e\n  \u003cli\u003eExtra-long flute series provides 1.25 inch length of cut for deep-reach applications\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction delivers rigidity and wear resistance in hard material grades\u003c\/li\u003e\n  \u003cli\u003e0.0625 inch nose radius for accurate ball-end profiling and 3D contouring\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting and right-hand flute direction compatible with standard CNC spindle rotation\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for operations where coated tooling is not required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and manual mills with precision collet or toolholder systems accepting a 0.125 inch straight cylindrical shank.

Ensure the machine spindle is fully stopped and the controller is in an e-stop or safe state before inserting or removing the tool. Because of the miniature diameter and extra-long flute length, use conservative feed and speed parameters and take light radial engagement passes to avoid tool deflection or breakage. Consult the manufacturer cutting data recommendations for the specific workpiece material grade before programming the operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.1250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.25 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: 0.1250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 20 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: Variable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.0625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000\/-0.0020 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Finishing\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\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\u003eLength Type\u003c\/strong\u003e: Extra Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 957308\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51743192383794,"sku":"957308","price":87.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5ec74c2d3cdbfbb41c8ebdef92eaf167_667573be-5729-4f48-9a43-760c8536185b.jpg?v=1788843785","url":"https:\/\/voomisupply.com\/products\/harvey-tool-957308-ball-end-mill-1-8-in-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
