The product contains three twist drills of different diameters (6, 8 and 10 mm) with an impressive length of 250 mm, which allows you to easily drill through thicker wooden materials without the need to change tools or drill bits repeatedly. This extra-long format also makes it easier to access hard-to-reach places, for example when assembling structures or assembling furniture elements.

Each drill bit in the set has a spiral shape that ensures quick chip removal and prevents jamming, which speeds up the work itself and at the same time reduces tool wear. Thanks to the high-quality manufacture of robust materials, the drill bits are suitable for both home use and semi-professional projects, as they offer reliability and a long service life.

The combination of different diameters means that you can always adapt the drilling to the desired dimension - regardless of whether you want to make a pilot hole or need a precise opening for a dowel or screw. The set stands out mainly for its practicality and the possibility of universal use in all types of wooden materials, from softwoods to hardwoods.

In addition to its ergonomics, it is also impressively compatible with all standard drills; they can be installed simply and quickly, and the spiral shape helps to make every drilling project truly smooth, clean and efficient.

Same summary

The KWB drill bit set with three different dimensions and an extra long spiral shape is particularly suitable for users who often drill into wood and need a longer reach or greater hole depth. Such a set is practical for DIYers in woodworking, furniture making or assembly, where classic drill bits are too short. For users with mainly basic needs in metal or other materials, this set may be a limitation, as its purpose is primarily aimed at working with wood.
