Description

Forstner Bits are excellent at producing clean flat-bottomed holes in wood (e.g. to locate Euro Hinges on kitchen unit doors).


Features and Applications

Some force is required to push them through the timber, so are best suited to use in a Drill Press. Since they locate mainly on their rim, with only a small central point, it is possible to drill a series of overlapping holes (e.g. to clear the waste from a Housing Joint).


Their name is derived from their inventor, Benjamin Forstner, an American gunsmith who patented the design in 1874. Saw Tooth variants are now available which cut a little faster and are more suitable for drilling into End Grain.
