Manufactured in the 16ER insert style with an HG330TR grade designation, it carries a TiC\/TiN coating that improves wear resistance and extends tool life in continuous threading passes. The insert features a 32 threads per inch (TPI) profile, a 3\/8 inch inscribed circle (0.3750 inches), and a thickness of 0.1460 inches. It is suited for machinists and toolroom operators running external Unified National thread forms on steel and similar workpiece materials where a durable, coated carbide insert is required.\u003c\/p\u003e\u003cp\u003eThis insert is applied in external threading operations where UN thread standards are specified. The 16ER style seats into compatible laydown threading toolholders used on manual and CNC lathes in production and job-shop environments. The right-hand orientation and 32 TPI profile make it a direct fit for threading tasks on smaller-diameter workpieces requiring fine Unified National thread pitches. Machinists producing threaded fastener features, fittings, and precision components will find this insert appropriate for medium to high-volume threading passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with TiC\/TiN coating for wear resistance in external threading\u003c\/li\u003e\n\u003cli\u003e16ER insert style for use in standard laydown threading toolholders\u003c\/li\u003e\n\u003cli\u003e32 TPI Unified National (UN) thread profile, right-hand external orientation\u003c\/li\u003e\n\u003cli\u003e3\/8 inch inscribed circle (0.3750 inches) with 0.1460 inch thickness\u003c\/li\u003e\n\u003cli\u003eZero-degree relief angle — insert geometry relies on toolholder for clearance\u003c\/li\u003e\n\u003cli\u003eHG330TR manufacturer grade designation for threading-specific carbide performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in laydown threading toolholders that accept the 16ER insert style.

Always power down and lock out the machine before changing inserts. Use the appropriate torque wrench per toolholder manufacturer specifications when tightening the clamping screw — do not over-tighten. Inspect the insert seat and clamping surfaces for chips or debris before seating a new insert to ensure proper contact and runout control.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 16ER\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: HG330TR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiC\/TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UN (Unified National)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: External\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 32 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1460 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.123 pounds\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: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: H08704199\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728872538418,"sku":"H08704199","price":213.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d74cb8de1a29ef7c6621f37025b3869d.jpg?v=1788697214","url":"https:\/\/voomisupply.com\/products\/hertel-h08704199-threading-insert-32-tpi-3-8-in-ic","provider":"Voomi Supply","version":"1.0","type":"link"}
