Honing is a process that is used to create a precise design on a metal surface by using an abrasive stone and a rotary motion. Honing is used to improve the texture of a surface or improve the geometric form of the surface.The scratches left in the metal surface after honing help to assist in retaining oil and improving lubrication, performance and cylinder life. Cylinder hones work well with most common metals.Cylinder hones come with a gritstone which can vary in size and a flexible drive shaft with an adjustable tension spring which can be used with air or electric drills. The drive shaft also allows for easy alignment whilst working.ApplicationsCylinder hones are suitable for use on:Brake and clutch cylindersBore engine cylindersMotorcycle engines
