Cylinder Hone 75-77mm 120 Grit Flexible Engine Bore Honing Tool

A flexible cylinder hone used to refresh the internal surface of engine bores before reassembly. Sized for 75-77mm cylinder work, this 120 grit honing tool is intended for breaking glaze and preparing the bore when it needs attention without moving straight to more involved machining.

Used in garage work, engine rebuilds and general workshop servicing, it suits mechanics and repair users carrying out cylinder maintenance on engines within the stated bore range. When a bore needs cleaning up and the surface prepared for the next stage of the job, a flexible engine bore honing tool like this gives a straightforward way to carry out that work during servicing or rebuild tasks.

The 120 grit is suited to glaze breaking and surface preparation, while the 75-77mm working range keeps it matched to the correct bore size. A 7.8mm shaft means this flexible hone needs to be paired with a suitable drive setup, and the maximum drive speed of 300rpm gives a clear working limit for controlled use. For regular engine servicing work, having the correct bore size and grit to hand helps keep preparation work consistent and avoids using the wrong tool on the job.
