Guhring introduces new drilling line

Providing power and outstanding results, Gühring says the holemaking benchmark has been taken to a new plateau with the RT100XF. 

Branded as ‘Extreme and Powerful’, the new RT100XF has been developed with all tool parameters optimised to generate outstanding feed rates and exceptional metal removal rates. Created to reduce cycle times for difficult-to-machine materials and special applications in series production, the extremely hard new drilling line is said to be extremely resilient to potential breakages. 

This bold claim is based upon the new carbide grade developed by Guhring for the RT100XF that performs a balancing act between hardness and toughness. The special structure of this Gühring created carbide grade has a re-sharpening effect, so breakages that normally accelerate tool wear no longer occur. This is supplemented by the proven nanoFire coating system that has been created by a specially designed pre and post-treatment that smooths the coating and makes it significantly more robust.

The design and geometry of the new RT100XF supports the robust performance of the carbide grade and surface treatment with an early double margin support that perfects the coaxiality to ensure perfect bore size and roundness. This makes the RT100XF a suitable drill for precision and concentricity for hole making from 5xD upwards. The new drill series also consists of support chamfers that ensure excellent running smoothness. Furthermore, polished flutes reduce the heat input into the component, this also supports the fast evacuation of chips and thermal changes such as hardening are avoided. The point geometry is protected by a negative chamfer and this makes the cutting edge ultra-robust and durable. 

The rounded edge preparation produces a stable and efficient cutting edge – this rounding is produced with precision to the micron, something that is made possible by Guhring’s manufacturing competence. The new through coolant drills are perfect for the drilling of structural and case-hardened steels, free-cutting and heat-treated steels, nimonics, titanium, inconel and hastalloy, making the RT100XF suitable for any machine shop. 

Available in 5XD and 7XD, the new drills can be purchased in diameters from 3mm to 20mm diameter with 0.1mm increments. Furthermore, the series is also offered with all common imperial dimensions. For additional information, please contact Guhring.
