Threading insert FANAR 16 IR 1.5 ISO BMA — internal threading plate for 1.5 mm pitch

FANAR 16 IR 1.5 ISO BMA is a threading insert engineered for internal metric threading with a 1.5 mm ISO pitch. The insert is intended for use in holders compatible with 16 IR size inserts and is suitable for turning centers and lathes where accurate form-cutting of internal threads is required. It supports production and repair operations that demand consistent thread geometry and repeatable results.

Advantages

The design delivers precise internal thread profiles and stable cutting performance in a compact insert format. Compatibility with standard 16 IR holders enables quick installation and replacement, reducing machine downtime. The insert provides predictable wear behavior and repeatable thread dimensions when used with recommended tooling and cutting parameters.

Suitable for

• Internal metric thread turning on lathes and CNC turning centers
• Production runs requiring consistent 1.5 mm pitch metric threads
• Repair and maintenance tasks that need accurate internal thread restoration
• Applications with holders designed for 16 IR size threading inserts

Key specifications

• Thread pitch: 1.5 mm (ISO metric)
• Insert type: internal threading plate for 16 IR holders
• Intended use: form-cutting internal threads
• Compatibility: designed for turning centers and lathes

How to use

Install the insert into a compatible 16 IR holder according to the holder manufacturer’s instructions and secure it with the appropriate clamping method. Set the lathe or turning center to the correct spindle speed and feed for the material and cutting conditions, and program or set the tool path to achieve a 1.5 mm ISO thread pitch. Use steady approach and retract motions to avoid chip packing in the bore and monitor insert wear to maintain thread quality.

Usage recommendations

Use suitable cutting fluids or coolant for the material being machined and select cutting parameters (speed, feed, depth of cut) that match the insert geometry and workpiece material. Inspect thread form after initial cuts and adjust settings if necessary to ensure accurate 1.5 mm ISO thread dimensions and surface finish.
