Threading Insert FANAR 22 ER 4.5 ISO BMA for External Thread Turning

FANAR threading insert 22 ER 4.5 ISO BMA for External Thread Turning is a replaceable cutting plate engineered for producing external ISO-profile threads on lathes. Designed to mount in compatible tool holders, the insert provides a defined cutting geometry that matches standard metric thread forms. It is intended for use in general metalworking and machining environments where repeatable thread geometry and rapid insert replacement are required.

Advantages

The insert offers consistent thread profile accuracy and repeatability across multiple workpieces, reducing the need for manual adjustments. Its replaceable design shortens downtime by enabling quick changeover without regrinding. The standardized ISO geometry ensures compatibility with common metric thread specifications and simplifies process setup on turning centers.

Suitable for

• External metric thread turning on lathes
• Batch production of threaded components
• Repair and maintenance tasks requiring standard ISO threads
• Workshop and industrial machining where quick insert changes are needed

Key specifications

• Type: replaceable external threading insert
• Thread profile: ISO metric thread geometry
• Application: external turning for thread cutting
• Compatibility: designed for insertion into matching external threading tool holders
• Material considerations: suited to machining common ferrous and non-ferrous metals when proper cutting parameters are applied

How to use

Mount the insert in the appropriate external threading tool holder designed for this insert style, ensuring secure clamping and correct orientation for the intended thread direction. Set the lathe to the required thread pitch and depth parameters that match the ISO metric profile. Perform test cuts on scrap material to verify thread form, fit, and depth before proceeding to production parts. Replace the insert when wear affects thread geometry or surface finish.

Usage recommendations

Use recommended cutting speeds, feeds, and coolant for the workpiece material to extend insert life. Verify tool holder compatibility and follow machine safety practices. Inspect inserts regularly and replace when tool wear compromises thread accuracy.
