Hertel H05767140 Threading Insert 14 Tpi Nptf Solid Carbide

Product Description

The HERTEL H05767140 is a solid carbide laydown threading insert designed for right-hand internal NPTF thread cutting at 14 threads per inch. Coated with a TiC/TiN finish for enhanced wear resistance and tool life, this insert features a 3/8 inch inscribed circle and a thickness of 0.146 inches. It carries an insert style designation of 16IR and a relief angle of 0 degrees, making it suited for rigid, precision threading operations in a laydown-style toolholder. Machinist and tool-room professionals working with tapered pipe threads specify this insert when NPTF thread form accuracy is required.

This insert is used in internal threading applications where NPTF tapered pipe thread standards must be met. Typical applications include threading bores for hydraulic fittings, fluid-system components, and pressure-rated pipe connections in metalworking and manufacturing environments. The solid carbide substrate handles interrupted cuts and hard materials where high-speed steel inserts would wear prematurely. Sold individually with a minimum order quantity of 10 pieces per order.

Key Features

• Solid carbide substrate for high rigidity and extended tool life in demanding thread-cutting applications
• TiC/TiN coating provides improved surface hardness and reduced cutting friction
• Right-hand internal cut geometry configured for NPTF tapered pipe thread standard
• 14 TPI thread pitch for 3/8 inch and related NPTF pipe thread sizes
• 16IR insert style for compatibility with laydown-style internal threading toolholders
• Zero-degree relief angle supports stable, chatter-resistant threading passes

Compatibility

Designed for use in laydown-style internal threading toolholders accepting the 16IR insert style. Verify toolholder seating pocket dimensions and insert style designation before installation.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer's clamping specifications. Ensure the machine spindle is fully stopped and the toolholder is secured before seating or removing the insert. Inspect the insert pocket for chips or debris prior to installation to ensure proper seating and thread-form accuracy. Handle carbide inserts with care to avoid edge chipping.
