Threading Insert FANAR 22 ER 3.5 ISO BMA — external threading plate 22ER3.5ISOBMA

FANAR 22 ER 3.5 ISO BMA is a replaceable external threading insert designed for lathe operations. It follows ISO threading geometry and is intended for producing or repairing external threads with a 3.5 mm pitch reference. The insert is made for use in turning tools and holders that accept 22 ER style inserts, providing a standardized cutting profile for ISO-compatible thread forms used in precision turning and repetitive production.

Advantages

The threading insert provides consistent thread profile accuracy due to its ISO-compliant geometry and repeatable seating in compatible tool holders. Its replaceable design reduces downtime by allowing quick index or insert changes without regrinding tooling. The standardized dimensions and stable cutting edge support uniform results across production runs and improve process predictability in external threading applications.

Suitable for

• External thread cutting on lathes
• Repair and reconditioning of external threads
• Series production where ISO thread form is required
• Operations requiring quick insert changes to minimize downtime

Key specifications

• Insert style: 22 ER external threading insert
• Thread pitch reference: 3.5 mm
• Thread standard: ISO-compatible threading geometry
• Mounting: designed for use in 22 ER style tool holders
• Application: external threading on turning machines

How to use

Install the insert into a compatible 22 ER style threading holder according to the tool holder manufacturer's instructions, ensuring correct seating and clamping torque. Set lathe thread parameters (cutting speed, feed corresponding to the 3.5 mm pitch, depth of cut and thread engagement) based on workpiece material and machine capabilities. Use appropriate coolant or lubrication as recommended for the material to control chip formation and temperature. Inspect thread form and dimensions after finishing passes and replace or re-index the insert when wear affects thread accuracy.

Usage recommendations

Choose cutting speeds and feed settings according to the workpiece material and follow the tool holder manufacturer's clamping guidelines. Monitor insert wear and surface finish; replace the insert promptly when dimensional tolerance or thread profile deteriorates to maintain consistent results in production.
