Hertel 16ERA60HG225TR Threading Insert Solid Carbide 3/8 Ic

Product Description

The HERTEL 16ERA60HG225TR is a solid carbide laydown threading insert designed for right-hand external threading operations on CNC lathes and turning centers. The insert uses a partial profile 60-degree thread form and covers a range of 48 to 16 threads per inch, corresponding to a metric pitch range of 0.50 to 1.50 mm. A PVD-applied TiAlN coating provides heat and wear resistance for threading in ferrous and stainless materials. The 3/8-inch inscribed circle and 0.146-inch thickness match the 16ER insert style seat geometry. This insert is installed by machinists and CNC operators in production and job-shop turning environments.

The 16ERA60HG225TR is suited for external threading passes on turned components where a 60-degree unified or metric thread form is required. The broad TPI range makes it a versatile choice for shops threading a variety of fastener-standard diameters without changing insert geometry. It fits toolholders designed for the 16ER laydown insert style and is intended for single-point threading cycles on CNC or manual lathes. Typical applications include threading steel, alloy steel, and stainless steel workpieces in industrial manufacturing settings.

Key Features

• Solid carbide substrate with PVD TiAlN coating for extended tool life in ferrous and stainless threading
• Partial profile 60-degree thread form covers 48 to 16 TPI and 0.50 to 1.50 mm pitch in a single insert
• Right-hand external cut orientation for standard CNC threading cycles
• 16ER laydown insert style with 3/8-inch inscribed circle and 0.146-inch thickness for precise seat fit
• HG225TR manufacturer grade indicates a wear-resistant PVD-coated carbide formulation

Compatibility

Designed as an OEM-style replacement insert for toolholders accepting the 16ER laydown insert style with a 3/8-inch inscribed circle seating geometry.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator with the machine in a stopped, locked-out state before any insert change. Use the correct torque wrench and manufacturer-specified clamp screw for the 16ER toolholder to secure the insert without cracking the carbide substrate. Inspect the insert pocket and clamp for chips or damage before seating the insert. Verify thread form and pitch against the job drawing before running the threading cycle.
