Hertel H08696569 Threading Insert 14 Tpi 3/8 Inch Ic

Product Description

The HERTEL H08696569 is a laydown-style threading insert designed for right-hand external UN thread cutting at 14 threads per inch. Built from solid carbide with a TiC/TiN coating, this insert delivers consistent thread form and wear resistance in demanding turning applications. The 16ER insert style features a 3/8 inch inscribed circle and a thickness of 0.146 inches. It is suited for use in CNC lathes and manual turning centers where external unified national thread profiles are required. Machinists and toolroom operators working with threaded components rely on inserts of this type for repeatable pitch accuracy and extended tool life.

This insert is used for external threading operations on metalworking lathes in production machining and toolroom environments. The UN thread standard makes it applicable to the widest range of inch-series threaded fastener and component work encountered in general manufacturing, maintenance machining, and repair. At 14 TPI, it is well matched to coarse-thread applications common in structural and industrial fastener work. The right-hand orientation suits standard-direction threading on conventional setups.

Key Features

• Solid carbide substrate provides rigidity and wear resistance for threading at consistent pitch
• TiC/TiN coating reduces friction and extends insert life in steel and ferrous alloys
• 14 TPI UN external thread standard covers a broad range of inch-series coarse-thread work
• 16ER insert style with 3/8 inch inscribed circle fits compatible laydown threading toolholders
• Right-hand cut orientation for standard-direction external threading
• 0 degree relief angle in a laydown geometry for stable seating in the pocket

Compatibility

Designed as an OEM-style replacement threading insert for 16ER-series laydown threading toolholders accepting a 3/8 inch inscribed circle insert with a 0 degree relief angle.

Installation Notes

Threading inserts should be installed by a qualified machinist following the toolholder manufacturer torque and seating guidelines for the specific pocket style. Power down and lock out the machine spindle before changing inserts. Inspect the toolholder pocket for chips or wear before seating the new insert, as debris under the insert affects thread accuracy. Handle solid carbide inserts carefully to avoid chipping the cutting edge prior to use.
