Polished surfaces are a must-have for all medical devices. This is the only way to prevent bacteria and viruses from settling on the surface. So, this instrument for minimally invasive surgery is also made of martensitic, stainless chrome steel. The material is not only very easy to polish, but also resistant to chemicals and acids.
However, one problem is that high temperatures develop at the tool’s cutting edge when drilling into this material, which can promote abrasive wear. This is particularly problematic in fully automated production, where high process reliability and therefore consistently high tool lives are required.
The RT 100 InoxPro Micro is Gühring’s high-end micro drill for machining stainless steels, special alloys and titanium. The optimised geometry with a concave main cutting edge helps to deliver an aggressive cutting behaviour. In this way, the micro-precision drill produces short chips even in long-chipping materials, making it easier for the chips to be removed. At the same time, the Perrox coating protects the tool from abrasive alloy components and prevents built-up edges. As a result, the micro drill achieves the highest feed rates with very long and reliable tool lives.
The new RT100 InoxPro range of high-performance solid carbide drills for machining stainless steel and titanium alloys. When machining these challenging materials, tool wear can be a formidable opponent to your productivity and performance. The new RT100 InoxPro overcomes these challenges with its new geometry that optimises chip formation. This combines with the ultra-smooth Perrox coating that enhances wear protection and an optimised carbide substrate that delivers the perfect balance of hardness and toughness. Available with 3XD, 5XD and 7XD variants from 3 to 20mm diameter with 0.1mm increments, this through coolant series will improve feed rates and tool life by more than 50% whilst improving process control and chip evacuation.
