More about Bahco Dynamic Drive 

Bahco Dynamic Drive is a technology that is used in Bahco’s socket and wrench products. It is designed to reduce wear and tear on nuts and bolts, as well as to reduce the risk of slipping or rounding off fasteners. The technology achieves this by providing a better grip on the fastener, distributing force more evenly, and reducing the stress on the corners of the nut or bolt. Overall, Bahco Dynamic Drive helps to extend the life of the tool and the fastener, making it a valuable feature for professionals and DIY enthusiasts alike.

  1. Products are designed and manufactured for professional use. Where permitted by law, all hand tools in the catalogue are offered with a lifetime warranty – a warranty against material and manufacturing defects for the normal lifetime of the tool in question. ‘Lifetime’ is defined as the period of time a tool can be expected to last under normal use and conditions.
  2. Any product that has been incorrectly used or incorrectly maintained, or that is worn from improper use or that has suffered unauthorized modifications, is not covered by this warranty.
  3. Any product that has been used under environmental conditions for which it was not designed or that has suffered any damage caused by external influences (water, salt water, chemical, physical, impact, extreme temperatures) or foreign substances is not covered by this warranty. In case of loss or the total or partial destruction of the product, the product is not covered by this warranty unless the beneficiary of the warranty provides precise technical proof of the origin of the claim, a material defect or a construction defect, and of the components of the product concerned.

  1. The following are excluded from the lifetime warranty: pneumatic tools, hydraulic tools, battery powered tools, electrical/electronic tools, torque tools, automotive tools, measuring tools, and tools which have specific warranty conditions.
  2. Batteries are warranted to be free of defects in workmanship and materials for a period of TWO YEARS from the date of original purchase. If inspection shows the issue is caused by defective workmanship or materials, the product will be repaired (or at our option, replaced) without charge if still within the warranty period. As a reminder, professional use is defined as use of the tool for purposes which are related to a trade, business, or profession of the user.
