Carmex 3/8EXRHAG60P25C Threading Insert Solid Carbide

Product Description

The CARMEX 3/8EXRHAG60P25C is a laydown threading insert designed for external partial profile threading operations on CNC lathes and turning centers. Built from solid carbide with a PVD-applied TiN coating, this right-hand insert cuts 60-degree thread forms across a pitch range of 0.50 mm to 3.00 mm (48 to 8 TPI). The 3/8 inch inscribed circle and 0.146 inch thickness conform to standard 16ER geometry, making it a direct fit in compatible toolholders. Rated at manufacturer grade P25C with material grade C5, it is suited for a broad range of workpiece materials in production threading environments.

This insert is appropriate for use in both light and moderate-duty external threading applications across a universal workpiece material range, including steel, cast iron, stainless, non-ferrous alloys, heat-resistant superalloys, and hardened materials. It is a standard choice for machinists and CNC operators running high-volume thread-turning cycles where consistent profile accuracy and coating durability are required.

Key Features

• Solid carbide substrate with PVD TiN coating for wear resistance and edge integrity
• 60-degree included angle for standard unified and metric external thread profiles
• Covers 48 to 8 TPI pitch range (0.50 mm to 3.00 mm) in a single insert
• Right-hand cut, partial profile design for versatile thread form coverage
• 3/8 inch inscribed circle, 0.146 inch thickness - 16ER standard geometry
• Meets CE, ISO 13485:2016, ISO 14001:2015, and ISO 45001 standards

Compatibility

Designed for use in 16ER-style external threading toolholders. Compatible workpiece material codes include H, K, M, N, P, and S, covering a universal range of metals and alloys per ISO classification.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Power down and lock out the machine before seating or removing inserts. Use the correct torx or hex key specified for the toolholder clamping screw and avoid over-torquing the clamp. Inspect the insert pocket and clamp for debris or damage before each insert change to maintain accurate seating and thread form repeatability.
