The EUROCUT team returned from the Canton Fair with valuable feedback from customers in various markets. During the exhibition, we had the opportunity to reconnect with long-term partners and meet many new buyers interested in cutting tools, drilling accessories, and practical solutions.
Besides product consultations, many discussions focused on actual working conditions, product durability, and technical challenges encountered in daily use. Two topics stood out at this exhibition: the increasing interest in saw blades and discussions about SDS drill bit breakage.

Understanding SDS Drill Bit Fracture
SDS drill bit fracture was another important topic discussed with customers during the exhibition.
SDS-Plus and SDS-Max hammer drill bits are designed to withstand repeated impact loads when drilling into concrete, masonry, and other hard materials. However, under certain operating conditions, drill bits may crack or fail prematurely.
Key Technical Factors:
SDS drill bits are subjected to repeated impact and torsional loads during operation. Over time, accumulated fatigue damage can lead to cracking, especially in areas subjected to repeated mechanical stress.
Friction between the drill bit and drilling debris, combined with repeated impacts, generates heat. Continuous operation, insufficient cooling, or excessive pressure can exacerbate heat accumulation. Depending on the material and heat treatment conditions, excessively high temperatures can affect hardness and mechanical properties, increasing the risk of premature failure.
SDS drill bits contain multiple structural transition zones, including the helical flute section, the shank transition zone, and the carbide tip connection. Changes in cross-sectional geometry can cause localized stress concentrations. Under repeated impact and torsional loads, these areas can become potential crack initiation points.
Different Fracture Types Require Different Analyses
It is also important to distinguish between different types of failure:
These failure types should not be attributed to the same cause. A proper investigation requires examining the fracture location, fracture surface, material properties, heat treatment, brazing quality, and actual drilling conditions.
"For manufacturers, this feedback is invaluable when reviewing product design, material selection, heat treatment, and manufacturing processes."
The Canton Fair is not just an opportunity to showcase our products but also a chance to listen to our customers, understand their practical application needs, and exchange technical knowledge.
At EUROCUT, we remain focused on the quality and reliability of our drill bits, saw blades, and other power tool accessories. We appreciate every customer who visited our booth and shared their experiences with our team.
We look forward to building stronger connections and creating more opportunities together in the future.
