Beschreibung

Step drill bit for installing Rotomatic type tuners.
– Shank: 9.9mm diameter
– 7.8mm and 9.9mm diameter holes are drilled at the same time
All of our step drill bits are made of HSS (high speed steel) and promise a fine job for making tuner holes. The drill bit blade is especially designed to drill hard woods like maple.
