Cylinder Hone 81-83mm 120 Grit Flexible Engine Bore Honing Tool

A flexible cylinder hone for working on bores in the 81-83mm range, used to clean up and refresh internal surfaces before reassembly or further machining. The 120 grit abrasive makes it suitable for general honing work where a more consistent bore finish is needed without being overly aggressive.

Used across garage work, engine rebuilding, restoration jobs and general workshop maintenance, this type of flexible hone is suited to internal cylindrical parts where the abrasive needs to follow the surface rather than cut in a fixed line. It can be useful when refreshing engine bores, tidying internal surfaces during servicing, or carrying out repair work on components that need a cleaner and more even finish before going back together.

The flexible design helps the hone follow the internal surface during use, which is useful when working inside bores where a rigid abrasive may not track in the same way. Its working diameter range is 81-83mm, with a 7.8mm shaft for powered use, and the maximum drive speed is 300 rpm. Sticking to the stated speed helps with control and allows the tool to work as intended during bore finishing and clean-up work. For regular maintenance or rebuild jobs, it is a practical way to handle general internal surface preparation without reaching for a more aggressive setup.
