Ruko Short Series Step Drills HSS Spiral Flute & Split Point ZR101SH
A step drill bit is a special metal drill bit designed for precise drilling in thin-walled materials such as sheet metal, aluminum, or plastic.Its characteristic shape consists of several defined drilling stages, each corresponding to a specific hole diameter. This allows different hole sizes to be produced with just one tool without the need to change tools.When drilling, the step drill bit gradually penetrates the material. With each step, the borehole is enlarged to the next diameter. The next stage simultaneously deburrs the previously drilled hole, resulting in clean hole edges.For this reason, the step drill bit is widely used in metalworking. It enables clean, uniform drilling and saves time on repetitive work.
The spiral flute has the advantage of optimizing the chip flow. Even long, non-breaking chips are removed easily. This process protects the cutting edges and reduces built-up edges. The cone shape allows the drills to be easily removed from the dri
lled hole. Each step drill is individually packed in a plastic box. Step drills are available in many sizes with various steps. Particularly suitable when working on switchboards and similar items.
