Ruko CBN ground spiral fluts enable very sharp and burr-free cutting edges compared to ordinary milled flutes. Especially the chip flow is optimised, so even long, non-breaking chips will be easily removed. The optimised chip flow protects the cutting edges and reduces built up edges and cold weld marks. Due to these special features, cutting performance and tool life are extended significantly.

Each step has a radially adjusted relief produced CBN grinding that relates directly to the diameter of the step. This means the cutting edge is always the highest point of the diameter.

Each step is axially CBN relief ground. This means the cutting edge is always the highest point of the axial cutting axis.

The cutting edge of each step has relief angle. This means the cutting edge is also the highest point in advance direction.

The CBN ground bit ensures centering and spot-drilling even in thin walled material.


Step drills are the ideal tool for sheet metal working in the following sectors of industries, Electrical (size 4 and size 9), Sanitary
Engineering and Heating Engineering (size 6 & 7), Automotive & Mechanical Engineering, Aviation (size 0/5, size 0/9, size 1, size 3,
