WTX-Quattro — the version with four guide landsThe new WTX-UNI range from Sheffield-based
Ceratizit UK and Ireland Ltd, offers reliable precision drilling in steel, stainless steel and cast iron while delivering outstanding cutting values. Furthermore, the cost-competitive drills are particularly sustainable and stand out thanks to their high flexibility and long tool life.
In modern manufacturing, companies are faced with the challenge of efficiently and precisely machining a wide range of materials. Frequent tool changes and the need to use specialised drills for each material inevitably lead to increased costs. The new WTX-UNI range offers an entirely new geometry with patented features.
Manuel Keller, technical product manager at Ceratizit, said: “Our universal WTX-UNI drill range provides the solution to these problems. Thanks to its versatility and performance, the range enables precision drilling in steel, stainless steel, cast iron and hardened steels up to 54 HRC. This reduces the selection of tools needed and increases the efficiency of the machining processes, which in turn lowers costs and boosts productivity.”
He continued: “These tools are the first solid carbide drilling tools made from CT-GS20Y, our most sustainable upGRADE carbide grade to date.” They enable a significant increase in performance and deliver even better cutting data as well as a longer tool life compared to their predecessors.
Pictured right: the WTX-Quattro is always equipped with coolant holesThe WTX-UNI has two guide lands and is available with diameters ranging from 3 to 20mm in hole depths 3xD and 5xD, with or without through coolant in each case, and in shank variants HA/HB/HE. The patented end geometry with convex main cutting edge and a point angle of 140deg ensures high tool stability combined with excellent self-centring, thus enabling outstanding cutting data. Together with the modern DPA74S coating and the expanding flute design, chips are evacuated without obstruction reducing the risk of chip jams or tool breakage.
Mr Keller explained: “The version with four guide lands is called WTX-Quattro. These drills are always equipped with coolant holes and are available in hole depths of 5xD, 8xD and 12xD.” One special feature for the 8xD and 12xD versions is that the point angle, which is 140deg in all other versions, is changed to 135deg, and only the top section is equipped with four guide lands and the DPA74S coating. He added: “Of course, the WTX-Quattro also comes equipped with all the features of the other products in the WTX-UNI range.” If, despite the wide range of tool options available, process-specific solutions are still required, custom special tools — such as stepped drills — can also be implemented with ease based on the WTX-UNI.
The WTX-Deep UNI deep hole drill offers maximum process security and reliability thanks to its new geometry and improved tool stability, which minimise tool breakage and rejects. The polished chip spaces with expanding flute design also provide an improved chip flow, permitting higher cutting values compared to the predecessor product. Four guide lands ensure high drilling and positional accuracy and reduce hole deviation to a minimum. The head is also coated with the innovative, high-performance DPX74-M coating, which significantly increases tool life.
Pictured left: the WTX-UNI The WTX-Deep UNI range of deep hole drills can be used universally with a wide range of materials, with a particular focus on ISO P (steel), M (stainless steel), K (cast iron) and in some cases also ISO S (heat-resistant). The range held in stock covers hole depths of 16xD to 50xD and is available in the diameter range of 3 to 14mm or 3 to 8mm (40xD and 50xD). Imperial dimensions are also available in the global portfolio. With the 3xD and 5xD variants in the new WTX-UNI range, there are also high-performance pilot drills available which have been perfectly adapted for use in combination with WTX-Deep UNI.
The WTX-UNI range of solid carbide drills combines the high performance of a versatile premium drill with the sustainability of the upGRADE substrate CT-GS20Y. This provides both economic and environmental benefits and also includes the specific Product Carbon Footprint (PCF). After use, the tools can be reground to their original geometry and the original coating re-applied. This, combined with the upGRADE substrate CT-GS20Y, makes the WTX-UNI drills particularly sustainable and resource-saving tools.
Mr Keller concluded: “With the new tools in the WTX-UNI range, we have updated our drill portfolio and optimised it for universal machining. But that is just part of our extensive range, which covers a broad spectrum of applications — from micro drills from Ø 0.1mm to high-feed drills or specialist drills for aluminium or nickel-based alloys, through to indexable insert drills, our range is packed with tools for almost any machining requirement.”
