Hertel H48441984 Boring Insert Wpgt Solid Carbide Tin

Product Description

The HERTEL H48441984 is a solid carbide boring insert designed for precision internal turning and boring operations on CNC and manual lathes. Manufactured to the WPGT insert style with an 80-degree trigon shape, this insert features a Physical Vapor Deposition (PVD) TiN coating over a C5 carbide grade substrate. The HF1 chipbreaker geometry promotes controlled chip evacuation in finish and light-duty boring applications. With an 11-degree relief angle and a 0.008 inch corner radius, the insert is suited for close-tolerance bores where edge geometry directly affects surface finish. Installation requires a compatible screw-clamping boring bar. Each package contains one insert; the minimum order quantity is 10 units.

This insert fits residential and industrial machine shop environments where small-diameter boring is performed on ferrous and non-ferrous workpiece materials. The WPGT insert style, 3/16 inch inscribed circle, and 1/16 inch thickness make it appropriate for compact boring bars and heads targeting tight bore diameters. The TiN coating provides surface hardness and lubricity for extended tool life in continuous light-cut operations. Machinists, tooling technicians, and CNC operators working with precision components typically specify this geometry for finishing passes where dimensional accuracy and surface finish are critical requirements.

Key Features

• Solid carbide construction with PVD TiN coating for wear resistance and lubricity
• 80-degree trigon (WPGT) insert shape with 11-degree relief angle for clearance in bored features
• HF1 chipbreaker geometry optimized for finish and light-duty boring passes
• 0.008 inch corner radius for controlled surface finish on close-tolerance bores
• Screw-mount insert holding method for positive, repeatable seating in compatible boring bars
• C5 carbide grade substrate suitable for a broad range of workpiece materials

Compatibility

Designed as an OEM-style replacement boring insert for screw-clamp boring bars and heads that accept the WPGT insert style with a 3/16 inch inscribed circle and 1/16 inch thickness.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before seating or replacing inserts. Use the correct torque driver for the clamping screw to ensure proper insert seating without over-stressing the carbide. Inspect the insert pocket and screw thread for chips or damage before installing a new insert.
