Hertel 16IRG60HG225TR Threading Insert Solid Carbide Tialn

Product Description

The HERTEL 16IRG60HG225TR is a laydown threading insert designed for internal partial profile 60-degree thread cutting on CNC lathes and turning centers. Manufactured from solid carbide with a PVD-applied TiAlN coating, this insert delivers consistent thread form across a range of thread pitches from 1.75 mm to 3.00 mm (14 to 8 TPI). The 3/8 inch inscribed circle and 0.146 inch thickness conform to the 16IR insert style standard. Right-hand cutting geometry makes it suited for conventional internal threading passes. Machinists and CNC operators working in high-volume threading applications will find the TiAlN finish extends tool life under dry or semi-dry cutting conditions.

This insert is intended for internal threading operations in a lathe or turning center environment, applicable to both job shop and production machining settings. It handles thread pitches spanning 14 to 8 TPI, making it useful across common fastener and pipe thread profiles cut in steel, stainless, and similar materials. The 16IR insert style seats in compatible laydown threading toolholders. Right-hand designation applies to standard bore threading where the tool advances away from the chuck. Sold individually; minimum order quantity is 10 units.

Key Features

• Solid carbide substrate for rigidity and wear resistance in threading operations
• TiAlN PVD coating improves heat resistance and extends cutting edge life
• Covers 14 to 8 TPI (1.75 mm to 3.00 mm pitch) with a 60-degree partial profile
• Right-hand internal cutting geometry for standard bore threading
• 16IR insert style with 3/8 inch inscribed circle and 0.146 inch thickness
• Laydown seat design for secure, repeatable insert positioning in compatible holders

Compatibility

Designed for use in 16IR-style laydown threading toolholders configured for internal threading applications. Verify holder designation accepts 16IR inserts with a 3/8 inch inscribed circle before installation.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is stopped and the turret is in a safe index position before changing inserts. Seat the insert fully in the toolholder pocket and torque the clamping screw to the toolholder manufacturer's specification using the correct Torx or hex key. Confirm insert orientation matches the required right-hand internal cutting direction before resuming operation.
