Guillet is a great brand in the drill bit industry.
Guillet brand drill bits have unmatched performance and robustness. They come on a plastic hanger and are perfect for drilling large diameters even deep.
You will be able to quickly clean them of debris thanks to 2 large flutes with aggressive rake angles, followed by 2 pronounced spirals that considerably improve the progress of the bit.
They integrate solid and resistant hard metal inserts placed asymmetrically, which break the material into large chips.
