I used it for the expansion of the seat tube of the chromoly frame It was supposed to be 27 mm in dimensions, but it looked like it could cut from 26.8 mm with a caliper, so I used it immediately with a 26.8 mm seat tube without problem 26. Since 8 mm was able to shed, we could gradually increase the size and expand it to 27.2 mm. Cutting while changing the dimension about 5 times It was possible to cut the sheet tube neatly with good sharpness
This time it was used as a dust cover around the gas piston of the gun to process and adjust the inner diameter of a commercially available aluminum pipe. The adjusterable reamer I purchased before used to adjust the choke size of the muzzle part of the shotgun. I like the point that it's easy to fine-tune the dimensions.
