Cordless Alliance System (CAS) is a cross-manufacturer battery pack system of currently 24 leading power tool brands.

ITH Bolting Technology is now official and exclusive partner of the Cordless Alliance System CAS


24 brands, more than 230 machines but only 1 battery system: The Cordless Alliance System (CAS) is a cross-manufacturer battery pack system of leading power tool brands. ITH Bolting Technology now extends the portfilio with the Battery Torque Wrench type ADS for torques up to 6,000 Nm (4,425 ft*lbs).


Meschede / Nütringen, Germany, May 2021. 

ITH develops precise bolting tools and system solutions for tightening and loosening bolt connections with thread diameters bigger than 16 millimeters (5/8”). The company from the Sauerland region in western Germany is a leading global system supplier in bolting technology - and now also part of the Cordless Alliance System (CAS). 

ITH is expanding the product portfolio of the cross-manufacturer cordless system initiated by Metabo to include the ADS battery torque wrench. 

"With ITH, we now have a strong partner on board who is a specialist for large bolt connections," says Metabo CEO Horst W. Garbrecht. "This shows that CAS is also the best choice in this industrial sector - when it comes to very high torques and bigger bolt connections."

Innovation and customer focus

Cordless torque wrenches up to 6,000 Nm are used for example on 

  • steel construction, 
  • commercial vehicles, 
  • construction machinery, 
  • cranes, 
  • wind turbines, or 
  • in the rail industry. 
Wherever large bolted connections are involved, precise bolting tools are required. 
"It was not only the quality of the rechargeable battery technology that convinced us, but also the previous, long-standing cooperation with Metabo in the development. We are an engineering company with a focus on innovation and customer focus – that is why cooperation in terms of engineering and development are important to us," says ITH president Frank Hohmann, who runs the global-acting family business ITH in the second generation together with his brother Jörg Hohmann. 
Jörg Hohmann adds: "The cooperation has always been very productive. So, it was only a matter of time for us to join CAS as well. At ITH, the benefits for our customers have always been at the center of our strategy, which is reflected in the so-called “ITH customer focus strategy”. When looking at CAS, professional users recognize the advantages of a cross-brand battery system. They are adding many highly specialized manufacturers to their own toolset - all based on powerful battery technology."

Battery torque wrench with optional turning angle function and digital data logging

The first CAS compatible machine from ITH Bolting Technology is the battery torque wrench type ADS. The small and lightweight battery nut runner with power classes up to 6,000 Nm (4,425 ft*lbs) has the best power-to-weight ratio in the market and turns off automatically as soon as the target parameters such as torque or turning angle angle (ITH option “ALPHA”) are reached. The ADS features a newly developed high-performance gearbox and a brushless motor, which is highly wear-reduced. 

"The ADS is the world's only cordless torque wrench in the segment for high torque values that can be optionally equipped with an external, digital control unit, the 'ADS Smart Control'," Frank Hohmann points out. "With one control unit, the bolting parameters such as torque or angle of rotation of several cordless torque wrenches can be set and documented centrally - ideal for series assemblies," explains Frank Hohmann. "Likewise, with the `Docu` option, we offer a version for digital documentation, which, in addition to the cordless technology, is a decisive trend in the market." 

The ADS is available in three versions:

  1. Basic, 
  2. Standard, and 
  3. Digital. 

System components such as supports can be designed according to customer requirements. Existing power sockets (hexagonal, hexagonal, hexagonal, or other) in the customer's inventory can flexibly be  exchanged on the square drive of the
cordless battery torque wrench - depending on the bolt connection.

About the Cordless Alliance System CAS

The Cordless Alliance System (CAS) is a cross-manufacturer battery system initiated by the Nürtingen-based (Germany) power tool manufacturer Metabo. CAS was launched in summer 2018 with nine power tool and machine manufacturers from different sectors. Currently, the companies Metabo, Rothenberger, Mafell, Eisenblätter, Collomix, Haaga, Electrostar (Starmix), Eibenstock, Steinel, Rokamat, Elried/edding, Birchmeier, fischer, Prebena, Cembre, Pressfit, Jöst abrasives, Gesipa, Trumpf, Monti, Baier, Scangrip and ITH Bolting Technology are part of CAS.

Within this battery system, which is unique in the industry, all machines of the CAS partners are one hundred percent compatible with one battery and can be combined in any way. Based on the powerful Metabo LiHD battery technology, CAS brings together the most diverse trades under one roof and thus offers professional users the freedom to work with standard and special products from various manufacturers in a mobile and flexible manner, far away from the power socket.
