It features a 0.375-inch cutter diameter and a 0.125-inch cutting width, with a straight tooth configuration and micrograin carbide construction that delivers consistent edge retention across a wide range of workpiece materials. The shank diameter matches the cutter diameter at 0.375 inches, and overall tool length is 2.5 inches. This cutter is used by machinists and toolroom technicians on CNC mills, manual knee mills, and horizontal milling machines where precise keyseat geometry is required.\u003c\/p\u003e\u003cp\u003eThis cutter is suited for keyseat operations in steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. The micrograin carbide grade supports use in both general production and demanding materials such as superalloys and titanium where high-speed steel tooling would wear prematurely. The bright uncoated finish makes it well-suited for non-ferrous materials and applications where coating interaction with the workpiece is a concern. Typical install scenarios include shaft keyway preparation in rotating machinery, drive components, and power transmission assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for extended tool life in ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003e0.375-inch cutter diameter with 0.125-inch straight cutting width for standard keyseat profiles\u003c\/li\u003e\n\u003cli\u003e8-tooth straight configuration for consistent chip load and smooth slot finish\u003c\/li\u003e\n\u003cli\u003eNeck diameter of 0.187 inches and neck length of 1.125 inches provide clearance for deeper slot access\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish compatible with non-ferrous metals and superalloys\u003c\/li\u003e\n\u003cli\u003e3\/8-inch shank for direct mounting in standard collets and end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 3\/8-inch collet chucks and end mill holders on CNC and manual milling machines.

Ensure the machine spindle is fully stopped and locked out before mounting or removing the cutter. Confirm runout at the cutter OD before beginning the cut, as excessive runout accelerates edge wear and reduces slot accuracy. Follow the machine manufacturer and tooling guidelines for feed rate and depth of cut appropriate to the workpiece material and machine rigidity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Material\u003c\/strong\u003e: Solid Carbide, Micrograin Grade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTooth Configuration\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Teeth\u003c\/strong\u003e: 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.187 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 1.125 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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeldon Flat\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Superalloys and Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Shank\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.45 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241631\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: INTERNAL TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 83-1270\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"INTERNAL TOOL","offers":[{"title":"Default Title","offer_id":67915374035250,"sku":"83-1270","price":137.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/24aa6f5148fceb2f561a38d800f87335_e8b5cb03-d36e-43f2-89b9-19d90981d98d.jpg?v=1791253329","url":"https:\/\/voomisupply.com\/products\/internal-tool-83-1270-woodruff-keyseat-cutter-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
