Threading Insert FANAR 16 ER 3.0 ISO BMA — 16ER3.0ISOBMA, external threading insert for lathe

FANAR 16 ER 3.0 ISO BMA is an external threading insert engineered for precision thread turning on lathes. Designed to comply with ISO threading geometry, this insert is intended to produce 3.0 mm pitch external threads using single-point or multi-point tooling holders. The insert is suitable for controlled metalcutting operations where consistent thread form and dimensional accuracy are required.

Advantages

The threading insert provides consistent ISO-compliant thread geometry and repeatable dimensional accuracy during external threading operations. Its design enables stable engagement with the workpiece when mounted in appropriate tooling holders, supporting reliable surface finish and thread profile control. The insert simplifies setup for producing standard 3.0 mm pitch threads and is compatible with common lathe turning workflows.

Suitable for

• External thread turning on lathes
• Single-point and multi-point threading toolholders
• Precision metalworking and component manufacturing
• Thread repair and batch production of standard metric threads

Key specifications

• Thread form: ISO metric external thread geometry
• Thread pitch: 3.0 mm
• Type: external threading insert for lathe use
• Compatibility: designed for use in single-point and multi-point tooling holders for turning

How to use

Mount the insert securely in a compatible external threading toolholder designed for lathe operations, ensuring correct orientation and clamping according to the toolholder manufacturer’s instructions. Set the lathe parameters—cutting speed, feed, and depth of cut—appropriate to the workpiece material and the 3.0 mm pitch threading operation. Use light, controlled passes to achieve the final thread profile and verify thread dimensions with appropriate gauges or measuring tools. Maintain coolant or appropriate lubrication as recommended for the material being machined.

Usage recommendations

Use tooling holders that provide rigid clamping and proper insert seat geometry to ensure stable cutting and correct thread form. Adjust cutting parameters according to material hardness and machine capability; softer materials typically allow higher feeds and speeds, while harder materials require reduced cutting speed and lighter depth of cut. Regularly inspect the insert for wear or chipping and replace when thread quality or dimensional accuracy deteriorates.
