Carmex 06IL20UNBXC Threading Insert 20 Tpi Left Hand Un

Product Description

The CARMEX 06IL20UNBXC is a solid carbide laydown threading insert designed for left-hand internal UN thread cutting at 20 threads per inch. It features a PVD-applied TiN coating over a solid carbide substrate, delivering wear resistance and thermal stability on a wide range of workpiece materials. The insert carries a 60-degree included angle and an inscribed circle of 5/32 inch (0.1563 inches decimal). At 0.073 inches thick, this is a compact insert suited for precision threading on CNC lathes and machining centers. Installation and tool selection are handled by machinists and CNC operators working to threading program specifications.

This insert is rated for universal primary workpiece material compatibility, covering material codes H, K, M, N, P, and S. That range includes carbon and alloy steels, stainless steels, cast irons, non-ferrous metals, and high-temperature alloys. It is appropriate for internal threading applications in production and job-shop environments where left-hand UN threads are required. The laydown style seating geometry positions the insert flat in the toolholder pocket, providing stable cutting forces during thread form generation.

Key Features

• Solid carbide construction with PVD-applied TiN coating for extended tool life
• Left-hand internal UN thread profile at 20 TPI with 60-degree included angle
• 5/32 inch (0.1563 inch decimal) inscribed circle for precise toolholder fit
• Universal workpiece material rating covering steels, stainless, cast iron, non-ferrous, and superalloys
• Laydown insert style for stable, repeatable seating in compatible toolholders
• Certified to CE, ISO 13485:2016, ISO 14001:2015, and ISO 45001 standards

Compatibility

Designed for use in toolholders accepting the 06IL insert style. Verify toolholder seat geometry and clamping system against the 06IL insert size code before installation. Compatible with left-hand internal UN threading operations across the listed workpiece material codes (H, K, M, N, P, S).

Installation Notes

Insert seating and clamping should be performed according to the toolholder manufacturer specifications using appropriate insert clamp screws and torx or hex keys. Power down and lock out the machine spindle before changing inserts. Inspect the toolholder pocket for wear or debris before seating the insert. Left-hand threading inserts require correct spindle direction and program offset settings confirmed before initiating a cut.
