Forstner Bits
The Forstner bit is a helpful wood drill for large holes. Unlike the twist drill, a Forstner bit has a short tip and no drill thread. With the aid of the centring point, the drill can be easily fixed in place when attaching.
The Forstner bit is used in woodworking mainly for making blind holes. For example, a knothole can be drilled precisely. Therefore, the Forstner bit is also colloquially called a knothole drill bit. Holes for top hinges in furniture are also made with that wood drill.

FAQ - frequently asked questions about Forstner Bits
The Forstner bit - named after its inventor, American Benjamin Forstner - is used in woodworking mainly for making flat bottomed holes. For example, a knot hole can be drilled out exactly and precisely. That is why the Forstner bit is also colloquially called knothole drill. In addition, it can also be used to make holes for concealed hinges in furniture.
Forstner bits belong to the category- wood drills and are therefore suitable for wood and wood-based materials.
Forstner drills are equipped with a centring point due to the diameter of the bit. It is important to make sure that this centre point is firmly held in the workpiece when the drill is applied. This is the only way to ensure that the drill does not slip during drilling and that a clean hole is produced.
Our assortment offers you a large selection of Fornstner bits. In our Classic range we offer bits up to Ø50 mm, Tool steel (WM) range up to Ø60 mm and in Tungsten-Carbide (HM) up to Ø60 mm.
The cylindrical drill is a variation of the Forstner bit. While the Forstner drill usually consists of a centre point, two main cutting edges and two closed circumferential cutting edges, the cylindrical drill is equipped with two open circumferential cutting edges. In general, the Forstner bit is ideal for free-hand applications and the cylindrical drill is ideal for working with a stationary device, such as a drill stand.
Drill bits with tungsten-carbide cutting edges generally have a longer service life and are particularly suitable for hard woods. Tthey are also ideal for wood-based materials such as MDF and chipboard.
Fornstner drills made of tool steel are ideal for drilling in soft woods.
