Installers' Drill Bits

Installers' drill bits (article 71) are made starting from a bar of special steel. After some working operations, on the special steel body is welded a bit made of an alloy containing Titanium, Tantalum, Cobalt. Thanks to these technical features, installers' drill bits can be used to easily drill iron, steel, stone, granite, ceramics, glass, wood, building materials and so on without having to change tool. For this reason, they are able to satisfy the needs of installers, that vary continuously.

Stella Bianca installers' drill bits have standard length and diameter between 4mm and 12mm. For further information, please check our Catalogue.

Seven pieces assortments are available too, supplied in handy tool holders.
