It measures 2.5 inches in overall length with a 3\/8 inch square shank, a 3\/8 inch long tip, and a 3\/32 inch tip thickness. The carbide tip delivers consistent radius geometry at 1\/8 inch, suited for generating smooth concave profiles in metal workpieces. This is a right-hand cutting tool, meaning it cuts when feeding from right to left. Machinists and tool-and-die technicians install this bit into standard square-shank tool holders for radius grooving, form turning, and profile finishing operations.\u003c\/p\u003e\n\u003cp\u003eThis tool bit is intended for use in metalworking applications where a repeatable 1\/8 inch concave radius profile is required. Typical use cases include turning radius relief grooves, form features on shafts, and decorative or functional radii on round stock. The RAD style configuration is common in production turning environments where interchangeable form tools are needed for consistent part geometry across runs. The right-hand orientation suits the majority of standard engine lathe and turret lathe setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCarbide tip construction for wear resistance and extended tool life in metal cutting\u003c\/li\u003e\n  \u003cli\u003e1\/8 inch concave radius geometry for precise form turning\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch square shank fits standard square-shank tool holders\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut direction — feeds right to left\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch tip length with 3\/32 inch tip thickness for controlled depth engagement\u003c\/li\u003e\n  \u003cli\u003eRAD style designation for compatibility with form tool holder systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style form tool bit for use in standard 3\/8 inch square-shank tool holders on manual and CNC lathes.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool bit is installed by qualified machinists into a compatible square-shank tool holder or turret block. Secure the shank fully in the holder and confirm center height alignment before cutting. Power down and lock out the machine spindle before seating or removing the tool bit. Inspect the carbide tip for chips or wear before each use, as a damaged tip will affect radius accuracy and surface finish.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRadius\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCut Type\u003c\/strong\u003e: Concave\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCut Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Length\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Thickness\u003c\/strong\u003e: 3\/32 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Size\u003c\/strong\u003e: 3\/8 inch square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: RAD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ACC-RAD4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728512287026,"sku":"ACC-RAD4","price":78.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2d9746c5422a771806b0b3166405ee39.jpg?v=1788692458","url":"https:\/\/voomisupply.com\/products\/accupro-acc-rad4-concave-radius-cutting-tool-bit-1-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
