Threading Insert FANAR 11 IR 1.5 ISO BMA — 11IR1.5ISOBMA, internal threading 1.5 mm pitch

FANAR threading insert 11 IR 1.5 ISO BMA is a replaceable cutting insert engineered for internal threading with a 1.5 mm ISO pitch. Designed for use in CNC and manual lathes, this insert provides accurate profile control to produce ISO-standard internal threads consistently. It is suitable for machining components in automotive, hydraulic and general engineering applications where repeatability and precise thread form are required.

Advantages

The insert delivers predictable thread geometry and consistent surface finish through a stable cutting edge and accurate profile geometry. Its replaceable design reduces setup time and tooling costs by allowing quick changes without regrinding. Compatibility with standard internal threading toolholders ensures straightforward integration into existing machining setups and supports both high-precision production and small-batch workpieces.

Suitable for

• Internal ISO-threading with 1.5 mm pitch on lathes
• Production and repair of automotive threaded components
• Machining hydraulic fittings and threaded housings
• General engineering parts requiring repeatable internal threads

Key specifications

• Thread type: internal ISO thread
• Pitch: 1.5 mm
• Insert form: replaceable cutting insert for internal threading
• Intended machines: CNC lathes and manual lathes
• Application areas: automotive, hydraulic, general engineering

How to use

Mount the insert into a compatible internal threading holder following the holder manufacturer's mounting torque and orientation instructions. Set cutting parameters according to workpiece material and lathe capabilities, beginning with conservative feed and speed values and adjusting to achieve the desired surface finish and dimensional accuracy. Use appropriate coolant or cutting fluid for the material being machined to extend insert life and maintain thread quality. Inspect the produced thread form with gauges or appropriate measurement tools to verify ISO compliance.

Usage recommendations

For best results, match cutting speeds and feeds to the workpiece material and use steady clamping to minimize vibration. Replace the insert at the first sign of wear affecting thread profile and maintain clean coolant to prevent built-up edge and premature wear.
