While cutting data is dependent on the component material and the tool set-up, including use of the correct toolholders, typically the HSS-E-PM drills will run at between 10 and 50 m/min surface speed.
The HSS-E-PM UNI series of drills is currently available in a diameter range from 1 through to 14 mm, with many incremental steps in between. Each drill is manufacture with a minimum 3xD flute length and, depending on diameter, up to 5xD. The drills are subject to WNT’s normal stocking criteria, meaning that if ordered before 6:30 pm they will be guaranteed for delivery the next working day, before noon for the majority of UK addresses.
The powder metallurgy used in the creation of the HSS-E-PM UNI drills ensures a uniform microstructure, which when combined with the high cutting edge stability and overall drill design featuring relief grinding, leads to enhanced process security. Performances is further enhanced by use of a universal PVD-TiN coating that provides heat and wear resistance in both low and higher speed cutting applications.
Says Tony Pennington, UK & Ireland managing director: “This gap between conventional HSS drills and solid carbide has now been filled with the HSS-E-PM UNI series, ensuring WNT customers can maximise productivity, whatever their drilling application.”
