RUKO high performance tube and sheet drills feature hard and durable flutes ground from solid hardened CBN. CBN (cubical boron nitride) is much harder abrasive than silicium carbide or corundum which enables to achieve better and sharper cutting edge free from burrs. Higher dimensional precision ensures long lasting drills with precise process tolerances. The drills prove an ideal tool for sheet metal working in several industrial sectors that include electrical, sanitary engineering, heating technics, automotive, mechanical engineering, switching systems and aviation.
The tough tool is also suitable for all standard industrial materials such as nonferrous metal, special steel, thermoplastics and duroplastics as well as sheet metals up to 4,0 mm thickness. The durable and versatile tool with its all in one smooth, high performance working cycle helps to center, spot-drill and bore. RUKO cutting spray or RUKO cutting paste increases the tool life.
