Hertel H05767777 Threading Insert 6 Tpi 1/2 in Ic Acme

Product Description

The HERTEL H05767777 is a solid carbide laydown threading insert designed for right-hand internal Acme thread cutting operations. Carrying the HG630TR manufacturer grade, this insert features a TiC/TiN coating that promotes heat resistance and wear life during threading passes. With a 6 TPI thread pitch and a 1/2-inch inscribed circle, it fits standard toolholders sized for the 22IR insert style. A 0.187-inch thickness and 1-degree relief angle provide clearance geometry suited to internal Acme thread profiles. Machinists and CNC operators working on leadscrews, power-transmission components, and similar Acme-threaded workpieces will find this insert a direct fit for production and repair applications.

This insert is intended for internal threading on lathes and CNC turning centers where Acme thread forms are required. Acme threads are common in linear motion hardware such as leadscrews, jack screws, and feed mechanisms across both industrial and commercial equipment. The 22IR insert style seats in compatible laydown threading toolholders. The TiC/TiN finish makes this insert suited to steel and alloy workpieces typically encountered in these applications. Each package contains one insert; the minimum order quantity is 10 inserts.

Key Features

• Solid carbide substrate for rigidity and wear resistance in threading operations
• TiC/TiN coating improves surface hardness and reduces heat buildup at the cutting edge
• 6 TPI pitch matches standard Acme thread specifications for leadscrews and power-transmission parts
• Right-hand internal Acme thread geometry for bore threading applications
• 1/2-inch inscribed circle suits 22IR-style laydown threading toolholders
• 1-degree relief angle provides proper flank clearance for Acme thread profile

Compatibility

Designed for use in 22IR-style laydown threading toolholders capable of accepting a 1/2-inch inscribed circle insert. Suited for right-hand internal Acme threading on lathes and CNC turning centers.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist following the toolholder manufacturer's specifications. Power down and lock out the machine before changing inserts. Inspect the toolholder pocket and clamping screw for debris or damage before seating the insert. Do not use damaged or chipped inserts, as carbide inserts can fracture under interrupted cuts or improper clamping.
