The Granlund System

Granlund’s unique tool system for countersinking and counterboring helps you to increase productivity and lower your costs. Our toolholders, counterbores, insert drills and pilots may be combined to fit all types of machines and applications. You can, with only 1300 parts, easily build more than 1 500 000 special tools. The system is grouped into 4 sizes: size 01, size 0, size 1 and size 2. All combinations have to be made with elements belonging to the same group size. Groups are not interchangeable. The range of tools available for each group size along with recommendations for correct tool selection and cutting data can be found in the following pages.
