Hertel H48441976 Boring Insert Wpgt Solid Carbide 3/16 Ic

Product Description

The HERTEL H48441976 is a solid carbide boring insert in the WPGT style, designed for precision internal boring operations on CNC lathes and machining centers. This trigon-shaped insert features an 80-degree included angle, a 0.004-inch corner radius, and an 11-degree relief angle, making it well suited for light to medium finishing cuts where close tolerances and consistent surface finish are required. Grade HT540B with a bright uncoated finish is appropriate for cutting applications where coating is not specified or where the workpiece material benefits from direct carbide contact. Installation is performed by a machinist or tooling technician using the screw-holding method.

This insert is used in boring bars and toolholders that accept the WPGT insert style with a 3/16-inch inscribed circle and 1/16-inch thickness. It is applicable in job shop and production environments for boring bores in ferrous and non-ferrous materials. The HF1 chipbreaker geometry is designed to promote chip control during light finishing passes. Typical applications include internal diameter finishing on small-bore components in both manual and CNC turning setups.

Key Features

• WPGT insert style with 80-degree trigon geometry for consistent cutting engagement
• Solid carbide construction, material grade C1, for rigidity and wear resistance
• HT540B manufacturer grade with bright uncoated finish
• HF1 chipbreaker for improved chip control on light finishing cuts
• Screw-holding method for positive insert retention in compatible boring bars
• 0.004-inch corner radius minimizes cutting forces on small, precise bores

Compatibility

Designed as an OEM-style replacement insert for boring bars and toolholders accepting WPGT-style inserts with a 3/16-inch inscribed circle and 1/16-inch insert thickness.

Installation Notes

This insert is installed and replaced by a qualified machinist or tooling technician. Always power down and lock out the machine spindle before changing inserts. Use the appropriate torx or hex key to secure the clamping screw to the toolholder manufacturer's specified procedure. Inspect the insert seat and clamping screw for wear or damage before installing a new insert.
