Always an idea ahead

HOLGER CLASEN's history impressively illustrates that it always pays to have the courage and vision to follow your ideas.

Read more about how the company has succeeded in continuously growing over the past 80 years to become the market leader as a result of constant product improvements, innovative ideas, and excellent customer service.


Hamburg native, Holger Clasen, recognised the need for good tools and improved applications. He established the company which bears his name on April 1, 1932 in Hamburg. As an equipment provider for the maritime industry, HOLGER CLASEN started out by supplying electrical tools and abrasives. In pursuing his ambitious aims he advanced the company and optimised the company's available products.

Holger Clasen:
"Nothing can stop technology's progress - we're standing in the middle of this change. Innovations and progress in mastering the matter mount before us so that one, having been caught up in this process, will hardly realise this tremendous development".

1939 - 1945

The company was destroyed several times by bomb raids in the Second World War. But nothing could stop Holger Clasen. He tirelessly rebuilt his company numerous times.


The founding father's courage and persistence finally bore fruit. HOLGER CLASEN became a flourishing post-war enterprise.

When Bernd Clasen, a second-generation Clasen, took over the management he recognised the advancing globalisation as an opportunity for the company and started creating important partnerships throughout the world.

The range of products was extended to include manual pneumatic tools. This move helped Bernd Clasen to successfully open up a new sales branch with numerous customers from the electrical and metal industry, the automotive industry and the plastics industry. HOLGER CLASEN was quickly seen as an expert in surface machining with pneumatic tools.

Bernd Clasen:
"Humans and their tools - striving to permanently improve themselves and their instruments. We attach particular importance to advising our customers about our products, from product selection to its application." This insight has translated into our corporate mission: Making work easier. It still holds true to this day.


HOLGER CLASEN was the first to introduce manually operated hydraulic cutting and crimping tools for cable assembly. With a capacity of 700 bars, they replaced the old, clumsy, low-power mechanical devices.

HOLGER CLASEN took initial steps towards automating grinding and screw-driving tools.


In the eighties, HOLGER CLASEN once again expanded its range of products by introducing pneumatic drives and calibrating systems.

In 1985, the company brought into the market battery-powered hydraulic cutting and crimping tools for cutting and connecting power cables. Competitors first laughed at the innovative battery technology. Very soon, however, the tools made by HOLGER CLASEN became the new norm.


With the REC-SAN tool, HOLGER CLASEN was the first manufacturer to present a battery-powered crimping machine for cold pressing for use in the plumbing sector, heralding another new technology shift.


The artist and sculptor Heinrich Eder created a silver-coloured sculpture named "Druck" (English: "pressure"), which was placed in front of the company building. The stainless steel life-size sculpture consisted of hundreds of VA4 sheets welded together. It showed a man squatting, pressing and shaping something invisible with his hands. The sculpture quickly became an expressive corporate symbol of HOLGER CLASEN, embodying our mission: Making work easier.


HOLGER CLASEN set up its Technical Service Center, giving HOLGER CLASEN's after-sales services its own face and acknowledging its great importance within the company.

ELWA®, the function control integrated in hydraulic crimping tools, was first presented and introduced. This technology controls and documents crimping operations.


Lennart Clasen became the new managing director. As the grandson of the founder, he heads the company in the third generation.

Once again HOLGER CLASEN set new standards: The company developed and marketed the quality documentation software DoQu®. At the same time, the ELWA® function control was refined. Today ELWA® is integrated in every battery-powered tool guaranteeing high quality results - at no additional fee.

Lennart Clasen:
"It's our philosophy to make work easier. We started out 80 years ago with this motto and continue its legacy today. That's why we offer ergonomic and efficient precision tools."


On April 1, the HOLGER CLASEN company turned 75. We celebrated this anniversary in September together with our closest customers and business partners in Hamburg. Our guests were invited to join us on the three-masted schooner Mare Frisium to sail through the port and down the Elbe river. While the impressive scenery drifted by, we travelled back in history to the roots of the family business. The day closed with a festive reception on the 20th floor of the Atlantic House at Hamburg's port. The breath-taking view offered an atmospheric stage for a glimpse into a promising future.


HOLGER CLASEN caused a few stirs within a rather short time by introducing new products incorporating innovative technology. The battery-powered hydraulic crimping and cutting tools of the Rapid series impressed users with multiple improvements such as a sturdier housing, the ELWA® basic function control, and small revolving heads. The two-step hydraulics and optimised rapid feed speed up cutting work.


HOLGER CLASEN successully introduced the quality management system DIN EN ISO 9001 on April 15, 2009.

The DuoLiner® created a new trend. Cutting and crimping heads can be changed quickly so that it is possible to use the same tool for cutting and crimping power lines. With a crimping/cutting force of more than 52 kN, the DuoLiner® exceeds the values of traditional handheld tools.


The manually operated RC 14-A crimping tool attracted attention due to its exceptionally high performance. At only six kilograms of weight, it has a crimping force of 14 tonnes equalling the weight force of 14 VW Golfs. As the only battery-powered tool in the world, it makes K38 crimps, which corresponds to a cable cross-section of 400 mm². New lithium-ion batteries provide the power machine with a battery capacity that is 65% higher than that of other tools.

Our corporate sculpture "Druck" was unfortunately stolen during the Hannover Fair. Created in 1997 this corporate symbol had adorned HOLGER CLASEN's trade fair booth for years.


More new HOLGER CLASEN products have conquered the market. HOLGER CLASEN has set new standards in rotor blade manufacturing with regards to the cutting and grinding of GRP material.

In November HOLGER CLASEN launched its new homepage. The website was completely redone and proudly presents itself in a new graphic design and clear structure. In addition to new products, new features include downloadable films about the company and HOLGER CLASEN tools.


HOLGER CLASEN celebrated its 85th anniversary with its employees and invited guests in September on the floating crane HHLA I KARLFRIEDRICHSTEEN with a maritime program in a relaxed and entertaining atmosphere. For additional entertainment, a HOLGER CLASEN Challenge was performed, in which the employees and guests could try HOLGER-CLASEN tools in the application to solve challenging speed and skill tasks.

Lennart Clasen:
"To facilitate the humans work was the mission from the very beginning of the company. This mission is still our vision. The success was not least characterized by numerous technical innovations, good and often self-trained employees as well as a globally networked corporate culture."
