Hertel H48442016 Boring Insert WPGT1.511 HT540B Carbide

Product Description

The HERTEL H48442016 is a solid carbide boring insert designed for precision internal machining operations on lathes and boring bars. 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.

This 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.

Key Features

• Solid carbide construction, grade HT540B, material grade C1
• 80-degree trigon (WPGT) insert shape for versatile boring applications
• 11-degree relief angle for improved clearance in internal bore work
• 1/64-inch corner radius (0.0150 inches) for precise finishing passes
• Screw-holding method for secure, repeatable seating in compatible toolholders
• Uncoated finish suitable for non-ferrous metals and other applications where coating is not preferred

Compatibility

Designed as a direct-fit replacement for WPGT1.511 insert pockets on boring bars and toolholders that accept the WPGT insert style with screw clamping.

Installation Notes

This 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.
