The first of its kind WTX HFDS from CERATIZIT: Innovative drill with four cutting edges

Many innovations, firsts or revolutions often turn out to be nothing more than facelifts or updates once you look under the bonnet. The same cannot be said for the WTX HFDS from CERATIZIT – without question the first and only four-edged high-feed drill on the market. Impressive cutting data and tool life in steel and cast iron materials clearly demonstrate the fourth cutting edge is not there just for show.

The superlatives that preceded the launch of the WTX HFDS raised expectations among potential users a notch higher: innovative, unprecedented results, a new benchmark in the drill segment. These are some of the comments on which the world’s first high-feed drill with four effective cutting edges, the WTX HFDS from CERATIZIT, will be judged.

“No matter what we put it up against, the WTX HFDS is faster every time! Machining times are reduced by up to 66% in comparison with standard two-edged and three-edged high-speed and high-feed drills!” says Felix Meggle, Ceratizit Group’s Product Manager Drilling Tools. Designed and engineered as a specialist tool for steel and cast iron, the WTX HFDS drill delivers exceptional performance in these materials.  “At high speed and ultimate in precision. If we replicated that performance on the road, we’d be getting a knock on the door from the police!” adds Felix Meggle. This increased performance has no impact on endurance, with tool life in excess of exiting competitor drills.

“The WTX HFDS is far more than just a speed and productivity merchant. It also delivers high quality in terms of positioning accuracy, tolerance and the roundness/cylindricity of the holes produced,” explains Felix Meggle. For example, average positioning accuracy of 0.03 mm for the entire hole depth can be achieved, which given the elevated cutting data is a significant achievement. With a WTX HFDS 6.80 mm diameter drill with a 5xD flute length drilling 1.7331 / 16MnCr5 steel a surface speed (Vc) of 120 m/min with a feedrate of 0.50 mm/rev is producing holes to an H7 tolerance. This is possible due to the innovative pyramid-shaped drill point, which is completely unlike a conventional chisel edge and allows for exceptional centring of the drill. Assisting the performance of the WTX HFDS drills are the four continuous spiral coolant holes that maximise coolant delivery to every cutting edge, while maintaining the drill’s core strength and stability. In addition, the WTX HFDS produces only a slight burr when entering and exiting the hole.

A global first like the WTX HFDS leaves nothing to chance, and the final piece of its development was the use of the legendary Dragonskin DPX14S coating from CERATIZIT. The TiAlN nanolayer is resistant to temperatures of up to 1000°C, clearing the last potential obstacle in the way of the new four-edged solid carbide drill delivering its exceptional levels of performance. The WTX HFDS drills are available in stock in diameters from 6.00 to 16.00 mm with deliveries commencing in May 2020 to coincide with the publication of the latest Up2Date catalogue
