Threading Insert FANAR 16 IR 3.5 ISO BMA for Internal Threading, Grade as Marked

FANAR threading insert 16 IR 3.5 ISO BMA is a replaceable cutting insert designed for internal thread turning with a 3.5 mm ISO pitch. It is made to fit toolholders for 16 mm shank systems and provides a defined geometry for ISO thread profiles, enabling precise internal thread form generation in metal turning operations. The insert's indexable design allows quick replacement and consistent cutting performance across production runs.

Advantages

The FANAR insert offers consistent thread profile accuracy due to its ISO-conforming geometry and precise cutting edges. Its indexable format reduces downtime by enabling fast insert changes without regrinding tools. Compatibility with 16 mm shank toolholders simplifies tool setup and replacement. The design supports repeatable internal thread machining, helping to maintain uniform part quality in series production.

Suitable for

• Internal thread turning on lathes with toolholders for 16 mm shanks
• Producing ISO metric threads with 3.5 mm pitch
• Series production and batch machining requiring quick insert changes
• Machining steel and other common metallic workpieces where ISO thread form is required

Key specifications

• Thread type: Internal threading insert for ISO metric profile
• Pitch: 3.5 mm
• Insert compatibility: Toolholders for 16 mm shank systems
• Design: Indexable, replaceable cutting insert
• Application: Metal turning for internal threads

How to use

Install the insert into a compatible 16 mm shank internal threading toolholder, ensuring correct orientation for ISO thread profile engagement. Set machine and spindle parameters according to workpiece material and recommended cutting speeds for internal threading operations. Use steady feed and consistent axial positioning to generate the 3.5 mm pitch thread; check thread depth and form with appropriate gauges. Replace the insert when wear affects thread accuracy to maintain consistent results.

Usage recommendations

Use appropriate coolant or cutting fluid for the workpiece material to improve surface finish and tool life. Verify toolholder alignment and machine rigidity before threading operations. Follow standard safety procedures when changing inserts and performing inspections.
