Thread turning insert FANAR 16 ER 14 W BMA — indexable carbide insert for external/internal threading

FANAR 16 ER 14 W BMA is a replaceable carbide thread turning insert engineered for external and internal threading operations. The insert follows the 16 ER series geometry and is intended for use in compatible toolholders for metalcutting applications where accurate thread profile control and fast indexable changes are required. It is designed to provide consistent cutting edges for repeated operations and to be integrated into established threading tool systems.

Advantages

The carbide construction ensures wear resistance and dimensional stability during threading cycles, supporting repeatable results across multiple parts. The 16 ER geometry provides a standardized seating and cutting orientation that simplifies insert replacement and reduces downtime. The insert's profile and cutting edge preparation are optimized for producing defined thread forms while maintaining predictable tool life under correct cutting parameters.

Suitable for

• External thread turning on lathes and turning centers
• Internal threading in bores and blind holes using compatible holders
• Series production where quick insert indexing reduces cycle time
• Workpieces made of common engineering metals suitable for carbide tooling

Key specifications

• Insert type: indexable carbide threading insert
• Geometry family: 16 ER series profile for threading toolholders
• Application: external and internal thread cutting
• Material compatibility: suitable for standard engineering metals when using appropriate cutting data
• Mounting: designed for toolholders accepting 16 ER style inserts

How to use

Install the insert into a compatible 16 ER series threading toolholder according to the holder manufacturer's instructions, ensuring correct seating and clamping. Set up the lathe or turning machine with the recommended spindle speed, feed, depth of cut and lubrication for the workpiece material; use proper thread pitch and profile settings to match the required thread form. Perform initial test cuts and fine-tune cutting parameters to achieve the desired surface finish and dimensional accuracy. Replace or index the insert when wear affects thread quality or dimensions.

Usage recommendations

Use manufacturer-recommended cutting speeds, feeds and coolant for the workpiece material. Verify toolholder compatibility with the 16 ER geometry before operation and conduct trial cuts when working with unfamiliar alloys or thin-walled components. Monitor insert wear and replace or re-index inserts to maintain consistent thread quality.
