For two months at the beginning of 2021, an artificial lake in Milan, Italy, was the setting for another spectacular use of TYROLIT drilling equipment. The task was a demanding one: in a first step, 32 holes had to be drilled and then poles had to be inserted, as they will serve as a mooring point for boats close to the shore.

The contractor of the project was Expertagli Aosta, a sub-company of the Edil Taglio Cemento Group, which is well known for professional drilling and cutting works in northern Italy. For this demanding job, the company decided to rely on TYROLIT equipment, as it was not feasible to be carried out with conventional machines.

 

 

Particularly challenging was the fact that the work had to be carried out in a water depth of four to five meters – with the visibility underwater being more than poor. Another challenge were the sediments on the bottom of the lake. For this reason, the use of TYROLIT special tools and machines was inevitable.

In total, 32 holes with a dimension of 350 mm x 4,000 mm had to be drilled. With a capacity for diameters up to 1,000 mm and the optimised drill bit attachment for large diameters, the DGB1000 drilling gearbox from TYROLIT was the perfect companion for this project. The DGB1000 was supported by the 25 kW PPH25RR drive, providing optimum cutting speeds with its 4-stage control.

 

 

The project was completed successfully within two months and the TYROLIT machines once again proved to be perfectly made for versatile and complex tasks.
