Cylinder Hone 68-70mm 180 Grit Flexible Engine Bore Honing Tool

A flexible bore honing tool used for cleaning up and finishing the inside of cylinders and similar openings. This cylinder hone suits 68-70mm bores and uses a 180 grit abrasive to refresh the internal surface without being aimed at heavy material removal. Used correctly, it is a practical option when a bore needs tidying before parts go back together.

Commonly used in garages, workshops and general engineering work, this type of flexible hone helps with cylinder freshening, bore clean-up and internal surface preparation. It will suit mechanics carrying out vehicle maintenance, servicing and rebuild work, as well as anyone working on tubes, housings or similar round internal openings within the stated size range. When a drill-driven hone is the sensible choice, it gives a straightforward way to improve the finish inside the bore before reassembly.

The working diameter is 68-70mm, making it suitable for matching bore sizes, while the 6.5mm shaft fits a suitable drive setup. A maximum speed of 300 rpm helps keep use controlled, so it should be run at a sensible drill speed rather than rushed. The flexible honing action allows the abrasive to follow the shape of the bore instead of acting like a rigid fixed tool, which is useful for light clean-up and surface finishing work. For regular maintenance and workshop jobs, that makes it a handy tool to keep close by when internal bores need attention.
