Threading Insert FANAR 22 ER 5.0 TR BMA — 22ER5TRBMA

Threading insert FANAR 22 ER 5.0 TR BMA is a replaceable cutting insert engineered for external threading operations on lathes and CNC turning centers. The design corresponds to a 22 series insert with a 5.0 mm pitch and TR geometry, enabling reproducible thread form and standardized indexing for repeatable results in industrial and workshop machining of metallic workpieces.

Advantages

The insert offers stable thread profile generation through precise geometry and consistent flank contact, reducing the need for manual adjustments. Its replaceable design allows quick changeovers and predictable performance across multiple machining cycles. Compatibility with standardized tool holders supports accurate positioning and indexing, helping to maintain thread accuracy and surface finish on external screw threads.

Suitable for

• External threading on CNC lathes and manual lathes
• Production and repair of metric threads with 5.0 mm pitch
• Series machining where repeatable thread form is required
• Workshops and industrial turning environments processing steel and other metals

Key specifications

• Insert series: 22 series profile
• Thread pitch: 5.0 mm
• Geometry: TR threading geometry for external threads
• Application: replaceable external threading insert for turning
• Compatibility: designed for standardized insert indexing and holders

How to use

Mount the insert securely in a compatible external threading tool holder with the correct seating and clamping torque. Set the lathe or CNC turning program to the required thread pitch and depth parameters for a 5.0 mm pitch profile. Use appropriate spindle speeds, feed rates and cooling/lubrication recommended for the workpiece material to minimize tool wear and achieve the desired surface finish. Inspect the first thread pass for dimensional accuracy and make fine adjustments to depth or offset as needed before proceeding with production runs.

Usage recommendations

For best results, select cutting speeds and coolant suitable for the specific metal being machined, and verify tool holder rigidity and insert seating before machining. Monitor insert wear regularly and replace inserts showing wear or chipping to preserve thread quality and dimensional repeatability.
