4 PLUS - Proven Millions of Times!
For use in concrete, masonry and natural stone.

On-the-job tests made under extreme conditions confirm that the DreBo Rotary Hammer Drill Bit's design 4 PLUS sets standards in terms of efficiency and performance.

This product has proven itself in the shortest possible time on millions of occasions. It has redefined the demands made of a professional rotary hammer drill bit.

The 4 PLUS significantly raised the performance parameters of drilling speed and life expectancy.

This considerably reduces the user’s cost per drilled hole. Modern heat-treatment procedures and a special surface finish reduce drill bit wear and improve resistance to bending forces. Constant research guarantees excellent uniform material structure and extremely tough soldered joints.

4 PLUS - 4 significant advantages

Due to its aggressive design, the fast and durable carbide tip allows easy centring and spot drilling – not even reinforced steel presents a problem.

The dynamic, chisel-shaped drill bit head rapidly penetrates the material, simultaneously channelling the drilling dust into the multi-flute spiral.

The patented, high-volume, multi-flute KVS-spiral quickly channels the drilling dust from the hole, saving both time and money in the process.

The unique reinforced flute geometry (KVS-flute) reduces vibration and transfers more impact energyfrom the rotary hammer to the drill bit head, increasing both drilling speed and life expectancy. Reduced stress for man and machine.
