Hertel H05766944 Threading Insert 14 Tpi Nptf Solid Carbide

Product Description

The HERTEL H05766944 is a laydown threading insert designed for cutting external NPTF threads on a lathe or CNC turning center. Built from solid carbide with a TiC/TiN multilayer coating, this insert delivers consistent thread form and extended tool life in steel and other ferrous materials. It operates at 14 threads per inch and carries an insert style designation of 16ER, making it a right-hand external threading tool. The inscribed circle measures 3/8 inches and the insert thickness is 0.146 inches. Licensed machinists and CNC operators in production and job-shop environments are the primary users of this tooling.

This insert is suited for threading applications that require NPTF tapered pipe thread profiles on external workpiece features. The NPTF standard is common in fluid-power, hydraulic, and pneumatic fittings where a pressure-tight mechanical seal is needed without a sealant compound. The 16ER insert style fits compatible toolholders designed for laydown-style threading inserts, making this a practical choice for shops already running that toolholder platform in precision turning or fitting production work.

Key Features

• Solid carbide substrate for rigidity and wear resistance in threading operations
• TiC/TiN multilayer coating improves surface hardness and reduces built-up edge
• 14 TPI NPTF thread form for tapered pipe thread profiles requiring pressure-tight fit
• Right-hand external thread orientation suits standard OD threading setups
• 3/8 inches inscribed circle with 0.146 inches thickness matches 16ER toolholder seats
• Zero-degree relief angle characteristic of laydown insert geometry

Compatibility

Designed for use in toolholders that accept the 16ER laydown threading insert style. Verify toolholder seat dimensions and insert pocket geometry before installation to confirm fit.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator with the machine powered down and the spindle locked. Use the correct torque-wrench driver for the insert clamping screw and follow the toolholder manufacturer's seating procedure. Inspect the insert pocket and clamping surfaces for chips or debris before seating the insert. Confirm thread form and pitch with a go/no-go gauge after the first test cut before running production.
