Blaser Swisslube entered a collaboration with Swiss tool and instrument manufacturer PB Swiss Tools with ambitious goals: to optimise processes, increase tool life and reduce production costs. A test phase proved successful, and the collaboration has now been expanded to include further production processes.
PB Swiss Tools’ history can be traced all the way back to 1878, starting with the production of nose rings for taming oxen in the village blacksmith’s shop in Wasen in Switzerland’s Emmental region. Since then the company has evolved over the years into an innovative global company synonymous with tools and medical instruments that are unrivalled for their precision and durability. It has been manufacturing tools since 1940, and medical products since 2013.
Today, specialists in more than 80 countries choose PB Swiss Tools when their work needs to meet the highest quality standards. With 180 employees at its facilities in Wasen and Sumiswald, PB Swiss Tools manufactures 12 million tools and instruments each year. More than two thirds of these are exported all over the world.
Blaser Swisslube’s Synergy 735 coolant, along with Blaser brand ambassador Titan Gilroy, caught the attention of PB Swiss Tools representatives at the Prodex exhibition in Basel. PB Swiss Tools Production Manager Patrick Gehrig was particularly interested in the holistic approach taken by Blaser Swisslube, increasing productivity and optimising costs through the use of the “Liquid Tool”.
“A visit to PB Swiss Tools’ shop floor was arranged to discuss potential collaboration,” explains Hans-Peter Dubach, Application Engineer at Blaser Swisslube.
This visit was entirely consistent with the overall approach adopted by Blaser Swisslube; in addition to talks and discussions, all the production details were closely examined.
“This includes an analysis of the water quality, the tools and machines used, as well as the materials processed,” Dubach explains. “We looked at all the upstream and downstream processes and identified potential for optimisation throughout: machine cleanliness could be improved, and the lathes were oily and sticky. We also believed that we would be able to improve tool life.”
The experts at PB Swiss Tools set themselves the goal of optimising processes, increasing tool life and reducing overall costs in collaboration with Blaser Swisslube. Following on from the detailed analysis, Dubach recommended using the crystal-clear Synergy 735 coolant with deionised water.
“This water-miscible and oil-free coolant allows for flawless surface quality, thanks to optimum additives,” Dubach says. “Rinsing behaviour is excellent, and the machines and tool surfaces are easy to clean.”
Synergy 735 also allows for a clear overview of the machining process and is characterised by a neutral odour and excellent skin compatibility. The minimal foaming means the coolant is also ideally suited to high-pressure systems.

Improved tool life
The new coolant was tested initially on a lathe over a period of three months. The results spoke for themselves: tool life was increased by around 10%, with process reliability remaining at the same level. The top-up rate was almost halved, which had a positive impact on overall costs. Both tool and coolant costs could be reduced. All process times have been observed. What’s more, the improved cleanliness of the tools and machines was enough to convince the managers at PB Swiss Tools.
Following on from this successful collaboration, further processes have already been tackled, aiming to optimise their results. These include new grinding processes, the use of cutting oils, the introduction of lubrication charts and streamlining of the range of lubricants. PB Swiss Tools and Blaser Swisslube will continue to strengthen their collaboration in future.
Patrick Gehrig is already looking to the future: “We rely on our coolant partner, Blaser Swisslube, and are committed to making continuous improvements in other areas.”
