RUKO UK offer a variety of Steps Drills in different materials and sizes, to suit all your needs:
High Speed Steel (HSS) - guarantees quiet running and high cutting performance.
TIN Coated - Titanium is a corrosion-resistant metal that is utilized as a coating on HSS drill bits to give them extremely high surface hardness levels in the form of titanium nitride, or TiN. Titanium-coated drill bits can drill through difficult materials and last up to six times longer than ordinary HSS bits.
RUnaTEC Coated - extremely high nano-hardness allowing high wear resistance and no material welding, ensuring a perfectly smooth surface.
Easy to control on sensitive materials such as thin sheet metal and Plexiglas, powerful on tough materials such as stainless steel. The new cutting geometry allows a soft, seamless transition between the different diameters.
Faster and higher service life than ever thanks to the new point cut, the specially developed chip space geometry and the optimization of the helix angle.
Versatile in its application, Plexiglas and wood can also be easily cut in addition to materials like steel and stainless steel, with the best drilling results at the same time.
