The Walter Titex UFL HSS-E grade high speed drill that significantly outperforms conventional drills, especially when drilling deep holes, according to the company.
 
The drill is characterized by a parabolic flute profile with a 50 percent larger web and more chip space than conventional twist drills and employs a helix angle of 40 degrees – the standard helix angle being 30 degrees. This design provides high rigidity and outstanding process reliability thanks to excellent chip formation and chip evacuation. Further, it reduces or eliminates the need for pecking cycles even at maximum drilling depths. In many applications, drilling to a depth of 10 to 12 × D without pecking is possible. In comparison, standard twist drills have to withdraw much earlier in order to allow for chip removal.
 
The new drill’s HSS-E (5 percent cobalt content) substrate provides high heat resistance and its TiAIN tip coating boosts cutting parameters and tool life, while its special U form point geometry promotes reliable chip formation and low cutting forces.
 
The drill is suitable for all ISO material groups and has a diameter range from 1 to 12 mm.
