  • For drilling steel and non-ferrous metal sheets with a thickness of 0.1 - 4 mm
  • For drilling hard plastics without cracking or tearing in thicknesses from 1 - 4 mm

Description

    A robust, powerful and precise tool with sharp edges, made on CNC machines, ground with CNB discs into the already cloudy HSS M2 material, with a 90° angle of transition to each next step:
    easy, even, fast successive drilling

    Deeply ground groove:
    easily removes even long chips created during drilling

    Made of HSS M2 material, with a polished surface:
    low friction, long service life, flawless design

    One drill for multiple sizes in three variants:
    9 degrees 4-12mm by 1mm, 9 degrees 4-20mm by 2mm and 14 degrees 4-30mm by 2mm

    Possibility of use in the speed range of electric and battery tools:
    wide application with commonly available tools

    Laser-marked diameters:
    easily visible, permanent, indelible marking

    Műhelykocsin használjuk. Csiga fúrókkal ellentétben fokozatosan fúrja a fémet és egy szerszám elég külömböző méretű lyukak fúrására. Jó minőségű szerszám fém tárolóban!

    We use it on a workshop trolley. Unlike auger drills, it drills the metal gradually and one tool is enough to drill holes of different sizes. Good quality tool in a metal case!
