Built to IDRT-61 industry standard, it features a micrograin solid carbide tip brazed to a rigid steel shank, delivering consistent thread form and extended tool life in production and job-shop environments. The 60-degree included angle suits unified and metric thread profiles. With a 3\/8 inch shank height and 3\/8 inch shank width, this bit mounts directly into standard square-shank tool holders. Machinists and tool-and-die professionals use this bit for right-hand internal threading passes where dimensional accuracy and surface finish are critical.\u003c\/p\u003e\u003cp\u003eThis tool bit is suited for internal right-hand threading on small-bore workpieces across a range of materials including steel, aluminum, and cast iron. The 2.5 inch overall length and 1 inch tip length provide adequate reach into bores with a minimum thread diameter of 0.45 inches. It fits standard IDRT-style boring bar holders and is appropriate for use on manual lathes and CNC turning centers in both production and maintenance machining environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide tip for improved wear resistance and sharper cutting edge retention\u003c\/li\u003e\n\u003cli\u003e60-degree included angle compatible with unified and metric thread forms\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for standard internal threading passes\u003c\/li\u003e\n\u003cli\u003e3\/8 inch square shank fits common IDRT-style tool holders without modification\u003c\/li\u003e\n\u003cli\u003eMinimum thread diameter of 0.45 inches suits small-bore internal threading applications\u003c\/li\u003e\n\u003cli\u003eMeets IDRT-61 industry standard geometry for consistent thread profile accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard fitment for IDRT-style single point threading tool holders accepting a 3\/8 inch square shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or toolroom technicians. Ensure the machine spindle is fully stopped and the tool holder is securely clamped before inserting or adjusting the bit. Set tool height on center with the workpiece centerline before threading passes. Inspect the carbide tip for chipping or wear before each use, as a damaged tip will produce out-of-tolerance thread forms.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: IDRT-61\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Bit Style\u003c\/strong\u003e: IDRT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Bit Type\u003c\/strong\u003e: Threading Tool\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Application\u003c\/strong\u003e: Threading\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Width\u003c\/strong\u003e: 0.375 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\u003eTip Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Thread Diameter\u003c\/strong\u003e: 0.45 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Material\u003c\/strong\u003e: Micrograin Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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-IDRT61\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51749592727858,"sku":"ACC-IDRT61","price":41.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7a81f5d2e59a7f65ee06f01ed808e219.jpg?v=1788908069","url":"https:\/\/voomisupply.com\/products\/accupro-acc-idrt61-threading-tool-bit-3-8-in-shank-rh-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
