Manufactured in the WPGT style with an 80-degree trigon shape, this uncoated insert carries grade HT540B and a C1 material grade designation. It features a 3\/16-inch inscribed circle, a 1\/16-inch thickness, and an 11-degree relief angle that supports clean chip evacuation in tight bore geometries. The 1\/64-inch corner radius (0.0150 inches decimal) suits finishing and light roughing passes where dimensional accuracy is critical. Machinists and tool-and-die professionals select this insert for applications demanding tight tolerances on interior diameters.\u003c\/p\u003e\u003cp\u003eThis insert is suited for boring operations on CNC lathes, manual lathes, and dedicated boring machines in job shop and production environments. The WPGT insert style and screw-holding method make it compatible with standard WPGT-style boring bar pockets. The uncoated solid carbide construction performs well in applications where a coated grade would generate excess heat or where coating adhesion to the workpiece is a concern, such as certain non-ferrous metals and cast materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction, grade HT540B, material grade C1\u003c\/li\u003e\n\u003cli\u003e80-degree trigon (WPGT) insert shape for versatile boring applications\u003c\/li\u003e\n\u003cli\u003e11-degree relief angle for improved clearance in internal bore work\u003c\/li\u003e\n\u003cli\u003e1\/64-inch corner radius (0.0150 inches) for precise finishing passes\u003c\/li\u003e\n\u003cli\u003eScrew-holding method for secure, repeatable seating in compatible toolholders\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for non-ferrous metals and other applications where coating is not preferred\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for WPGT1.511 insert pockets on boring bars and toolholders that accept the WPGT insert style with screw clamping.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis insert is installed and replaced by machinists or toolroom technicians using standard insert-seating procedures for screw-held boring inserts. Power down and lock out the machine spindle before changing inserts. Use the correct torx or hex key as specified by the toolholder manufacturer to seat the clamping screw to proper engagement without overtightening. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: WPGT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 1.511\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Trigon (80-degree included angle)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: HT540B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 1\/16 inches (0.0625 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inches (0.0150 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: H48442016\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51749751587122,"sku":"H48442016","price":161.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/01f9b4765b191a022ebecf2781223d33.jpg?v=1788909963","url":"https:\/\/voomisupply.com\/products\/hertel-h48442016-boring-insert-wpgt1-511-ht540b-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
