Gühring 245 HSS Straight Shank Twist Drills (Made in Germany)

HIGHLIGHTS:

The Gühring Exclusive Line - RT 100 U (Series 245) is a premium, high-performance solid carbide drill engineered for universal application across a wide range of materials. Part of Gühring’s renowned Exclusive Line, this tool is designed for professionals seeking maximum productivity and process reliability. Its specialized A-coating (TiAlN) provides superior heat resistance and hardness, significantly extending tool life even when operating at high cutting speeds in demanding materials like stainless steel, cast iron, and special alloys.

Featuring a reinforced web and optimized flute geometry, the RT 100 U ensures exceptional chip evacuation and structural rigidity, preventing tool deflection during drilling. The m7-tolerance shank and precision-ground cutting edges allow for high-accuracy hole sizing and excellent surface finishes. Its self-centering 140° point angle reduces axial forces and eliminates the need for center drilling or spotting in most applications, streamlining your machining workflow.

Constructed from ultra-fine grain carbide, this drill balances toughness with wear resistance. It is designed to withstand the thermal shocks of modern CNC machining while maintaining a sharp, stable cutting edge. Whether you are tackling batch production or complex one-off components, the RT 100 U delivers the "universal" performance required to reduce tool inventory and increase machine uptime.
