The set includes 16 extra-long 90mm bits, which means easier access to tight spaces in engines, furniture or electrical installations. The bits cover the most common dimensions and profiles, and the included M-case ensures excellent organization and always tidy tools in the workshop, car or in the field.

The main technical advantage is the standard 1/4" (6.3 mm) interface, compatible with most manual and electric screwdrivers. This makes it easier to quickly change bits and more flexible while working. In addition, the set also includes various screwdrivers and extensions, so you can immediately use it on various projects without additional purchases.

It stands out for the exceptional length of the individual bits, which is a rarity in the world of tools - especially in sets. This advantage allows you to work in deep holes where standard bits cannot reach, while at the same time reducing the risk of damaging the screw head due to more stable wrench guidance. The ergonomic case makes transport, visibility and use easier at every step.

If you're looking for a versatile, organized and useful set with long attachments, this KWB set is a great addition to your toolbox. It will give you the confidence to tackle even the most complex tasks - efficiently and without unnecessary complications.

Same summary

The KWB socket wrench set in a practical case with 16 extra-long bits (90 mm long) is particularly useful for users who often work in hard-to-reach or deep places - for example when servicing cars, repairing garden machinery or doing home installations. Thanks to the 1/4" drive and a variety of bits, it is suitable for light to medium-duty tasks where precision and good reach are more important than robustness. In the case of very demanding service work on tightly tightened screws or larger dimensions, it may also make sense to check out more robust sets with a larger drive.

The special feature of this set is the very long design of the bits, which allows access to screws where regular wrenches cannot reach.
