Anyone that needs to machine a range of materials in their daily business will be grateful for anything that can make their job easier. One example would be the ability to reduce the range of drills needed to just a few essentials, provided that they can deliver sufficient performance in the most common materials. And that’s exactly where the new WTX-UNI range from CERATIZIT comes in, offering reliable precision drilling in steel, stainless steel and cast iron while delivering outstanding cutting values. What’s more, the drills are particularly sustainable and stand out thanks to their high flexibility and long tool life without stretching the budget.
In modern manufacturing, companies are faced with the challenge of efficiently and precisely machining a range of different materials. Frequent tool changes and the need to use specialised drills for each material inevitably lead to increased costs. “Our universal WTX-UNI drill range provides the solution for these problems. Thanks to its versatility and performance, it 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,” says Manuel Keller, Technical Product Manager at CERATIZIT.
Sustainable carbide, high-performance and long tool life
The new WTX-UNI range offers an entirely new geometry with patented features. “These tools are the first solid carbide drilling tools made from CT-GS20Y: our most sustainable upGRADE carbide grade to date,” adds Manuel Keller. They enable a significant increase in performance and deliver even better cutting data as well as a longer tool life compared to their predecessors.
The WTX-UNI has two guide lands and is available with diameters ranging from Ø3 to 20 mm in hole depths 3xD and 5xD, with or without thro’ 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 140° 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 and reduce the risk of chip jams or tool breakage.
“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,” says Manuel Keller. One special feature for the 8xD and 12xD versions is that the point angle, which is 140° in all other versions, is changed to 135°, and only the top section is equipped with four guide lands and the DPA74S coating. “Of course, the WTX-Quattro also comes equipped with all the features of the other products in the WTX-UNI range,” adds Manuel Keller. And 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.
Hassle-free deep-hole drilling with the WTX-Deep 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.
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 Ø3 to 14 mm or Ø3 to 8 mm (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.
Full performance from 99% recycled raw materials
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.
“With the new tools in the WTX-UNI range, we have updated our drill portfolio and optimised it for universal machining. But that’s just part of our extensive range, which covers a broad spectrum of applications: from micro drills from Ø 0.1 mm 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!” says Manuel Keller.
