About this deal

Our Lewis pattern are characterised by a milled helix. This kind of helix warrants the highest bending stiffness at maximum chip space. Therefore our Augers Bits remove the wood chips without any problems. the ‘Douglas’ Auger Bit: patented in Germany, is manufactured by twisting flat bars. It has a double-thread helix, two taper taps and two main cutting edges. Auger Bits are indispensable if you need to drill especially deep holes into wood. They have a large coiled chip space, whereby the chipped wood are carried out to the tool shank during the drilling. There are three different auger bits which differ according to the type of helix. Today, because of the universal characteristics and the modern manufacturing techniques, only the milled ‘Lewis’ auger bits are readily available. These auger bits have one taper tap, one main cutting edge as well as a crest of thread, which is particularly suitable for soft wood and European hard wood. The mode of operation is similar to the Forstner Bit: First the taper tap will pre-cut the wood fibre of the outer cross ring, then the main cutting edge will do the main work.
