Hertel H48442008 Boring Insert WPGT1.511 HP520B Carbide

Product Description

The HERTEL H48442008 is a solid carbide boring insert designed for precision internal turning and boring operations on CNC and manual lathes. Manufactured to WPGT1.511 geometry in the HP520B grade, the insert features an 80-degree trigon shape with an 11-degree relief angle. The PVD-applied TiN coating reduces friction and extends tool life across a range of ferrous and non-ferrous materials. At 3/16 inches inscribed circle and 1/16 inches thick, this insert fits compact boring bar assemblies. It is suited for finish and semi-finish boring where close tolerances and consistent surface finish are required. Licensed machinists and CNC operators install and index this insert type.

This insert is used in boring bar toolholders that accept the WPGT screw-clamp style. Typical applications include internal diameter finishing on production runs in job shop, aerospace, and general metalworking environments. The 80-degree trigon geometry provides good access to tight bores and stepped features. The 1/64 inch corner radius is suited for light finishing cuts where minimal material removal per pass is needed. The C5 material grade handles general-purpose steel and cast iron at moderate cutting parameters.

Key Features

• Solid carbide construction in C5 material grade for consistent edge integrity
• TiN coating applied via PVD process for improved wear resistance and reduced built-up edge
• 80-degree trigon (WPGT) shape with 11-degree relief angle for clearance in tight bores
• 1/64 inch corner radius for finish and semi-finish boring operations
• Screw-clamp insert holding method for secure, repeatable seating in compatible toolholders
• 3/16 inch inscribed circle fits compact boring bar assemblies

Compatibility

Designed as a screw-clamp style replacement boring insert for toolholders accepting the WPGT1.511 insert geometry. Verify toolholder pocket dimensions and insert seating before use.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque wrench and clamp screw specified by the toolholder manufacturer when seating the insert. Inspect the insert pocket and clamp screw for debris or damage before seating a new insert.
