CUTTING TOOLS FOR HYDRAULIC HAMMERS
In order to avoid breakages and unexpected maintenance during demolition work, the choice of tool is very important and should be made mainly according to: type of excavator, type of hydraulic breaker, type of soil. With EXTREME Tools we can offer cutting tools for any type of application and ground conditions. Every production stage, from machining to treatment, from painting to testing, takes place in Italy, making Extreme Tools 100% Italian product. The choice of steels and the heat treatments aim to obtain the right compromise between wear resistance and toughness in order to assure a prolonged product life even in the most extreme working conditions. With Extreme Tools brand, we produce tools for any need and for all types of hydraulic hammer and breakers on the market. We realize several proﬁles and special shapes also upon customer’s drawing.
TYPE OF STEEL
Our tools use a hardening steel with a nickel component that increases the thermal conductivity during the treatment, allowing to have a homogeneous hardness between the external surface and the heart of the tool.
At the time of purchase, the steel undergoes an initial ultrasound check to look for any internal anomalies. Surface imperfections are eliminated during the processing phase. In this stage, 6 mm up to 10 mm of material are removed depending on the diameters.
After processing, a dimension check is carried out just before the heat treatment.
The production cycle ends with the hardness check. Hardness must remain in a range between 48 HRC and 50 HRC (higher values increase the fragility of the tool and the chance of break and failure). The hardness check is carried out on every single tool we produce, with a single impression for lengths up to 800mm; and with two or three impressions for longer lengths.
5 TIPS TO AVOID PREMATURE WEAR
- Do not give blank firing
- Do not use the tool as leverage to move boulders
- Do not beat the tools in the same place for too much time
- Always work perpendicular to the ground
- Lubricate the tool regularly
