THE DRILL FORSTNER:
The classic Forstner drill bit has a shank, a blade and a cylindrical drill head provided with a centre point, two main cutting edges and two opposing continuous peripheral cutting edges.
These peripheral cutting edges have a carve effect. When they are drilling in soft and long-fibered wood, they cut the wood fibres and produce a clear tear free-bore wall.
Furthermore the continuous peripheral cutting edges ensure that the drill has a od guidance when used with a hand drill. With a od Forstner bit it is possible to generate pitch holes on the work piece border without the drill running off. As well for boreholes that do not run exactly at a 90° angle, it is a od partner.
The Forstner drill is the perfect tool when it comes to drilling clean and precise holes in soft wood and in bigger diameters.
Founded in 1865, FAMAG has acquired more than a 140 years of expertise in the production of drilling and cutting tools for woodworking, especially for the famous Forstner drill. Today, due to a sophisticated geometry and further technical details as well as constant development, not only has the FAMAG Forstner drill a significantly lower evolution of heat as a conventional Forstner bit but therefore also a significantly increased service life.
THE INDEPENDENT TEST :
In April 2008, 18 different brand Forstner drills were tested by the American magazine "Fine Woodworking". The FAMAG Forstner drill was awarded the title "BEST OVERALL”. “They have the longest rims but tight machining tolerances. As a result they cut accurately, run cool, and are easy to operate.” This report can be downloaded from our website www.famag.com.
