The RT 100 S drill from Guhring was especially developed for the complex machining of steel materials. It reportedly scores points thanks to high cutting values and consistently good hole quality. An especially stable and accurate cutting edge is produced thanks to the special micro-geometry.
The extremely smooth surface finish of the RT 100 S web thinning and flute profile reduces the friction between drill and chip. The machining temperature is reduced and chip evacuation improved. Cutting forces are reduced. These tool features result in maximum hole quality and tool life, according to the company,

- tool steels
Group of alloy steels which, after proper heat treatment, provide the combination of properties required for cutting tool and die applications. The American Iron and Steel Institute divides tool steels into six major categories: water hardening, shock resisting, cold work, hot work, special purpose and high speed.
On a rotating tool, the portion of the tool body that joins the lands. Web is thicker at the shank end, relative to the point end, providing maximum torsional strength.
