These HSS Wood drill belong by their special characteristics to the highest quality of its kind. The special fully deep hole spiral slide the wood chips easily, thus reducing significantly the heat which typically generated during chip removal. This makes these tools much more durable.
In practice, this means that you can drill into a course over the complete spiral length with FAMAG wood twist drills HSS-G, while the chips are transported like in a screw conveyor. Yes, even when the drill lengths 315 and 400mm! This is not only joy but also saves much time.
In order to make a very clean hole entry roughing taps are required. Of course, these drill have two CNC-ground roughing taps. For optimal hole edge quality, we have gained a lot of experience and grind to a sophisticated geometry: Sure made in Germany! By the way not matter whether right or left hand! What is meant is that we manufacture these tools also with left cutting.
