With a 1\/2-inch inscribed circle and a neutral cutting direction, it mounts efficiently in compatible on-edge toolholders and delivers consistent thread geometry across a range of pitches. The insert carries a Titanium Nitride (TiN) PVD coating applied over solid carbide substrate, improving surface hardness and extending edge life when cutting steel and stainless steel. Machining shops and CNC lathe operators use this insert where thread quality and tool longevity are critical production requirements.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for threading operations on CNC lathes and manual turning centers in job shop and production environments. It supports internal threads from 5 to 24 TPI, covering a wide range of unified and metric-pitch equivalent thread families within the 60-degree V standard. Primary workpiece materials include steel and stainless steel, making it a practical choice for general machining and precision component work. The negative rake geometry and on-edge orientation provide stable cutting action and predictable insert seating during both roughing and finishing thread passes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with PVD-applied Titanium Nitride (TiN) coating for extended edge life\u003c\/li\u003e\n  \u003cli\u003e60-degree V thread form supports both external and internal threading in a single insert style\u003c\/li\u003e\n  \u003cli\u003eInternal TPI range of 5 to 24 covers a broad spectrum of thread pitches\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch (0.5000 inch) inscribed circle with neutral cutting direction for flexible toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003eNegative rake angle and on-edge series design provide rigid, chatter-resistant cutting geometry\u003c\/li\u003e\n  \u003cli\u003eCountersunk mounting hole (0.2030-inch diameter) for secure clamping in on-edge insert holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in on-edge threading toolholders that accept TNMC-style inserts with a 43 insert size code.

Power down and lock out the machine spindle before seating or changing the insert. Ensure the countersunk clamping screw is torqued per the toolholder manufacturer's specification to prevent insert movement during the threading cycle. Inspect the insert seat for chips or debris before each installation to maintain accurate thread geometry.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TNMC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 43\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: DVP656\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: 60 Degree V\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: External and Internal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInternal Threads Per Inch\u003c\/strong\u003e: 5 to 24 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inches (1\/2 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0030 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Corner Radius\u003c\/strong\u003e: 0.0050 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2030 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Shape\u003c\/strong\u003e: Countersunk\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1870 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: On-Edge\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: DORIAN TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 73310172010\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DORIAN TOOL","offers":[{"title":"Default Title","offer_id":67911763558706,"sku":"73310172010","price":213.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_24016ce1-739d-4646-ae6c-907cedaece8b.jpg?v=1791219073","url":"https:\/\/voomisupply.com\/products\/dorian-tool-73310172010-on-edge-threading-insert-1-2-inch-ic","provider":"Voomi Supply","version":"1.0","type":"link"}
