Hertel H05095062 Boring Insert WPMT32.51GP HP210B Carbide

Product Description

The HERTEL H05095062 is a solid carbide trigon boring insert in the WPMT style, designed for precision internal boring operations on CNC lathes and machining centers. The insert carries the HP210B manufacturer grade and features a multilayer CVD coating sequence of TiN, TiC, TiCN, and TiN, which builds wear resistance and thermal stability across a broad range of cutting conditions. With an 80-degree included angle, an 11-degree relief angle, and a 1/64 inch (0.0150 inch) corner radius, this insert is suited for finishing and semi-finishing passes where dimensional accuracy and surface finish are critical. Installation requires a screw-holding method compatible with WPMT-style toolholders.

This insert is intended for use in boring bars and toolholders designed to accept the WPMT insert style with a screw-clamp holding method. The GP chipbreaker geometry targets general-purpose turning and boring applications in steel and alloy materials classified at the C5 carbide grade range. It fits standard WPMT32.51 toolholder pockets and is appropriate for shop environments running production turning, job-shop boring, or maintenance machining work. This insert is typically installed and set up by machinists, toolroom technicians, or CNC operators working on turning equipment.

• WPMT insert style with screw-holding method for secure, repeatable seating
• 80-degree trigon shape with 11-degree relief angle for positive cutting geometry
• 1/64 inch (0.0150 inch) corner radius suited for semi-finish and finish boring
• GP chipbreaker for general-purpose chip control in steel and alloy applications
• C5 material grade compatible with a wide range of workpiece materials

Compatibility

Designed for use in WPMT-style boring bars and screw-clamp toolholders accepting the 32.51 insert size code with a 3/8 inch inscribed circle.

Installation Notes

Insert installation should be performed by a qualified machinist or CNC operator with the machine powered down and the spindle locked. Use the correct torque driver for the WPMT screw-clamp pocket to avoid damaging the insert seat or clamping screw. Inspect the toolholder pocket and seating surfaces for debris or wear before installing a new insert. Always verify tool offset and perform a test cut before running production.
