SATRA 3-PIECE SET OF FLEXIBLE HONING BRUSHES.

A set of self-centring internal brushes with a finish of flexible silicon carbide balls, designed for edge cleaning, surface finishing and honing.

•  Ideal for a wide range of applications in the automotive and aerospace industries, as well as in hydraulics and heating systems, and for machining valves and pipes.
•  For machining cylinders prior to fitting new piston rings.
•  They produce uniformly ground surfaces with a high coefficient of contact.
•  Honing does not increase the cylinder bore – it restructures the surface. The use of grinding oil is recommended.
•  The honing marks ensure the necessary oil retention.
•  For use with screwdrivers and drills.
