Cylinder Honing Brush, K120

This professional K120 honing brush is designed for the finishing and surface treatment of engine cylinders, hydraulic cylinders, plumbing systems and aerospace components.

The self-centring construction uses flexible silicon carbide abrasive balls to produce an even surface finish without changing the cylinder diameter.

Cylinder Finishing

The honing brush creates a uniform surface pattern that supports correct oil retention and load-bearing capacity.

It is suitable for deburring, final finishing and preparing cylinder bores before installing new piston rings.

The brush can be operated with handheld drills or stationary machines, making it suitable for various workshop and production applications.
