The TOUGH cut has been specially designed for tough operating conditions such as in shipyards, foundries and steel construction. It is also ideal for all demanding production environments where frequent tooth breakages and other damage to conventional burs occur. This set contains five tungsten carbide burs for tough applications in the most common shapes and dimensions. The sturdy plastic box protects the burs against dirt and damage. The burs are secured at the shanks, facilitating their selection and withdrawal. The box also has five unused holes for additional burs.
