A collection of five British-made Trubor high-speed steel (HSS) spiral-fluted reamers, comprising two machine reamers and three hand reamers. Sizes range from 1/4" to 5/8", all marked H7.
All five reamers are supplied with their original orange Trubor protective cases.
All five reamers are marked H7, indicating their intended hole tolerance classification.
Used workshop tooling – previous usage unknown. These reamers have come from a private engineering workshop and may have been purchased for individual machining jobs before being returned to storage.
The reamers generally appear clean and well preserved, with no obvious significant damage to the cutting edges on visual inspection. Some show minor surface marks or discolouration consistent with storage and previous handling.
None has been tested for sharpness, cutting performance or dimensional accuracy.
The original orange protective cases show age-related marks and wear.
