ARM external thread cleaner
Where surrounding components restrict space, the slim ARM heads are an option. The linear brushes require less radial clearance than a comparable circular-brush arrangement.
What matters when selecting a tool.
Typical applications include foundation bolts positioned close together. Measure the free radius from the bolt centre to the obstruction and take the drive unit into account. A nominally suitable thread range alone is not sufficient.

* Length: cleaning travel for external cleaners, overall length for IRK. Maximum speed is an upper limit, not a general operating recommendation. The documentation for the supplied version is authoritative.
Data sheet & manual
The PDFs are original manufacturer documents in the stated language. For operation, the instructions belonging to the supplied version apply.
Check the data sheet against the version.
Differences between the documents and the online table
The supplied data sheet and ARM manual specify M6–M22, M23–M42, M43–M64 and M64–M88, each with 200 mm cleaning travel. The online table gives narrower ranges and 160/150 mm cleaning travel; for the largest head, the outside diameter is 153 rather than 150 mm. This website uses the online table for preliminary selection. At dimensional or range limits, please have the specific version confirmed.
