Products - Rotary Hammer Drill Bit - 4 PLUS
4 Plus

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 core-reinforcement (KVS) guarantees a high break resistance.
The geometry ofthe core-reinforcement (KVS) ensures that the impact
energy of the rotaryhammer will be transferred with a high efficiency directly
from the power toolto the drill bit tip. This generates a fast drilling progress.
The 2-fluted geometryof the drill bit provides a fast removal of the drilling
dust.

 

 
 

PGM tested drills:
they live up to their reputation!

Our masonry drill bits bear the mark of conformity of the Prüfgemeinschaft Mauerbohrer e.V. (PGM), which is granted only to selected manufacturers.

PGMWE

Drill bits with this mark are guaranteed to conform to strict criteria regarding the diameter
of the carbide tip, its symmetrical soldering, and the concentricity
of the drills.

Only PGM tested drill bits are used by anchor manufacturers and institutes for the development and approval tests of new anchors.

Insist on the PGM mark of conformity the next time you purchase a high quality drill bit. You can rely on it!
