With 3-zone tempering technology, additional breaking points (power grooves) and hexagonal design.
Up to 30% higher removal rate
The buffer section is designed to have a lower hardness level (approx. 48 HRC). The higher level of elasticity means that this section is effective at damping any vibrations that occur, thereby significantly lowering the risk of breakage at the insertion end.
Considerably longer service life
The insertion end is designed to be harder (approx. 52 HRC), which extends the service life considerably.
Chisels remain sharp
The working area made of 60 HRC quality steel is extremely hard and therefore particularly tough.
Minimal risk of sticking in materials in comparison with round versions
