Cylinder Hone 81-83mm 180 Grit Flexible Engine Bore Honing Tool

A flexible cylinder hone for lightly refining the inside of bores from 81mm to 83mm. The 180 grit surface is suited to controlled finishing work where you want to clean up an internal surface without being too aggressive.

Used for bore finishing in garages, workshops and engineering settings, this type of tool helps when working on cylinders, tubes and other internal bores within the stated size range. It is useful during vehicle maintenance, repair work and reassembly jobs where a smoother internal finish can help parts seat and move properly. For anyone tidying up a used component or carrying out light internal surface preparation before fitting parts back together, it gives a straightforward way to refine the bore surface.

The flexible design helps the hone follow the internal surface during use, making it suitable for controlled bore preparation rather than heavy material removal. A 7.8mm shaft allows fitting into suitable drives, and the maximum running speed is 300rpm. Keeping to that speed helps the tool work as intended and makes handling more predictable during finishing work. The 81-83mm working range covers a specific bore size band, which is useful when carrying out regular maintenance or workshop jobs on matching components.
