Frequently asked questions

Fastening screws manually can be very tiring for muscles in the long term. The electrically assisted speedE® does the laborious task of fastening for you. You can finish tightening carefully by hand with a deft touch. The speedE® weighs just fraction of what a conventional battery-powered screwdriver does, meaning it is less heavy for the user to hold. There is no impact on the wrist either, unlike many battery-powered screwdrivers. Thanks to its electric ratchet function and award-winning SoftFinish handle shape, this e-screwdriver noticeably reduces strain on joints, tendons and muscles. All these reasons have convinced German doctors and therapists at German Campaign for Healthier Backs, so the speedE® is permitted to bear the campaign’s seal as an exceptionally ergonomic tool.

The speedE® combines the advantages of a screwdriver and a power tool. Light and compact, it offers the same advantages as a conventional VDE screwdriver when used in combination with slimBits. It also fastens screws electrically up to 0.4 Nm, enabling the end user to work quickly and comfortably. The material protection function activates from 0.4 Nm, allowing the end user to tighten the screw carefully by hand. The user can carry the speedE® in their pocket at all times, unlike a bulky, heavy battery-powered screwdriver, making it ideal for use when out on jobs. Thanks to its interchangeable Wiha slimBits, it can handle numerous different screw profiles. All these features mean that the speedE® can perform all standard types of fastening task without the need to carry around a large toolbox or battery-powered screwdriver.

In-house comparison tests at Wiha have shown that screws can be fastened at least twice as fast with the speedE® as they can by hand with a conventional screwdriver. This saves the end user time while increasing their work efficiency.

Thanks to the material protection function, you have full control over the tightening force with the speedE®. On reaching 0.4 Nm, power-assisted fastening switches off automatically to protect the material and users can finish fastening carefully by hand. This prevents any damage to the material. Combined with VDE-tested slimBits, the e-screwdriver is approved for use on live parts up to 1,000 V AC and offers the end user full protection during their daily work.

The speedE® contains a precise mini-motor which does not overheat when used for a long period of time, unlike power tools. The speedE® is optimally suited for use as a portable device thanks to its compact design. The speedE® weighs just fraction of what a conventional battery-powered screwdriver does, meaning it is less heavy for the user to hold. The speedE® causes no impact on the wrist either, unlike many battery-powered screwdrivers. Thanks to its material protection function at 0.4 Nm, the speedE® does not damage the work piece, unlike power tools. Higher torque values can be achieved by hand. The force applied can be limited to defined torque values when the speedE® is used in combination with easyTorque adapters. Another advantage over power tools is that, as a VDE- and IEC-certified product, the speedE® is approved for working on live parts up to 1,000 V AC when used in combination with slimBits and easyTorque adapters. It thus offers full protection during daily work.

Yes, the speedE® has two directions of rotation, meaning electrically assisted fastening can be used to fasten and undo screws. All you need to do is to use your thumb and index finger to turn the ring switch on the handle to the left or right as required.

No, the speedE®’s electric drive stops automatically at 0.4 Nm. You can then apply higher torque values by fastening by hand. Controlled fastening in higher torque value ranges is also effortless with speedE® when it is used with Wiha easyTorque adapters. easyTorque adapters are available in a torque range between 0.8 and 4.0 Nm and are included in the speedE® sets 2 and 3.

The speedE® impresses thanks to the combination of the following characteristics:

# Precise mini-motor with overload protection

# Ergonomic handle, approved by the AGR and recommended by doctors and therapists

# Material protection function at 0.4 Nm

# Long lifespan

# Electronic ratchet function

# Different screw profiles can be used thanks to slimBits

# With LED light

# Drive chain (motor, gears, electronics) uncouples automatically for manual fastening, allowing it to be used as a fully-fledged screwdriver

# VDE-certified slimBits and torque adapters, suitable for working on live parts

The speedE® has an IP44 protection rating and is thus protected against splashing water.

The speedE® is designed for daily professional use and has undergone a whole variety of tests. As a result, it is a robust tool which does not sustain any damage when dropped from normal working heights.

We recommend wiping the speedE® with a damp cloth to remove any dirt or residues.

Even when permanently used to fasten several hundred screws, the speedE® does not reach a critical temperature and is not damaged. You can still hold it in your hand.

The speedE® can be used in an ambient temperature between 0 and 40 °C.

The speedE® is available in just one power class. The e-screwdriver’s electric drive stops automatically at 0.4 Nm. Higher torque values up to 8 Nm can be achieved by hand.

No, the e-screwdriver has just one speed setting and an idling speed of 215 min-1.

The speedE® is only compatible with the insulated, VDE-certified Wiha slimBits. This is to ensure the user’s safety and protect them against danger when working on live parts. Bits, socket nuts and blades with a 1/4” slot are not compatible with the speedE®.

As with other battery-operated devices, it is recommended to remove the battery from the speedE® for longer storage periods and keep the battery in a cool, dry place.

Yes, the LED light starts to flash when the battery capacity is low and there is less than 20% power remaining.

The AGR e.V (German Campaign for Healthier Backs) has awarded the speedE® its seal as an exceptionally ergonomic tool. The AGR gives recommendations for products which prevent back pain and musculoskeletal disorders. Owing to its strict test criteria and an awarding committee comprising renowned medical experts, the AGR quality seal enjoys a high level of approval within the medical community. Thanks to its award-winning SoftFinish® handle shape, the speedE® noticeably reduces strain on joints, tendons and muscles. It is recommended by German doctors and therapists at German Campaign for Healthier Backs for this very reason.

As with normal screwdrivers, it is important to remove dirt and residue from the speedE® before putting it away to ensure a long service life. The gripping surface must be free of oil and grease since a slippery handle means the tool cannot be used safely. It is recommended to store the speedE® in a dry place.

The two speedE® batteries must be packed into your hand luggage when you fly. Pack the L-Boxx with the speedE® and accessories into your hold luggage that you check in. This applies to flights within Europe and the USA. Observe the local applicable regulations for all other countries. Li-ion batteries are subject to hazardous goods requirements.

It is possible to send the speedE® as air cargo provided the packaging is open. You must observe special packaging and labelling requirements if you are using a third party to ship the speedE®.

The speedE® has been tested by an independent laboratory and meets all relevant statutory and standard specifications (CE Conformity).

"You will find the operating instructions for the speedE® and its charger under downloads for the speedE® product in the Wiha online shop.


Ensure that you take electric tools, batteries, accessories and packaging to be recycled in line with environmentally friendly practices. Do not throw electric tools or batteries away with household waste. European directives state that used or defective batteries and electric tools which can no longer be used must be collected separately and taken for recycling in line with environmentally friendly practices. You can dispose of the tool in local return and collection systems.

The speedE® packaging has been manufactured with environmentally friendly materials and is FSC-certified. You can dispose of the speedE® cardboard packaging in the paper waste container if it is no longer needed. However, please ensure that you remove the battery inserted into the side of the upper cardboard layer before disposal.

No, the electric drive stops at about 0.4 Nm, but this value is for guidance purposes only. The tightening torque depends on many different influencing factors, such as the battery level, the outside temperature or the type of screw fastening (hard/soft).

To cut steel wire, diagonal cutters are best; the precision mechanic's diagonal cutters (order no. 36189) are better, for instance. Electronics pliers are more suitable for cutting soft to medium-hard wires.

Above all, burr-free cutting is important to prevent a potential risk of injury. If the cable tie tail is not cleanly cut, painful scratches or cuts may result. To ensure the clean, flush cutting of cable tie tails, precision mechanic's diagonal cutters are especially suitable. (Order no. 36189). Thanks to their specially milled precision cutting edge, cable ties and soft and medium-hard wires can be cut flush.

A bevelled edge or outer cutting bezel serves to ensure the stability of the cutting edge in terms of damage through increasing the cutting angle.

A cutting edge with bevelled edge generally has a significantly higher cutting angle (with Wiha approx. 76°). Nevertheless, this means that the user requires more cutting strength as soon as the cutting angle is increased. If a hard wire is cut using a cutting edge without bevelled edge, however, the cutting edge is unlikely to withstand the force and will become deformed. This is why cutting edges without bevelled edge are predominantly used in electronics (cutting copper or aluminium wires), or by plastic cutters.


Stripping is used to describe the removal of the outer sheath of a cable or installation cable. The outer sheath is removed using a cable stripping knife or stripping pliers. The individual wires are therefore left exposed.

Skinning is the procedure used to remove part of the insulation sheath of an electrical conductor to a specific length required for connection.


Laut den Normen DIN und ISO lautet die korrekte Bezeichnung für das Werkzeug Schraubendreher. Dennoch konnte diese Bezeichnung sich im allgemeinen Sprachgebrauch bis heute nicht durchsetzen. Stattdessen wird immer noch der Begriff Schraubenzieher verwendet, der seinen Ursprung durch das Ein-bzw. Festziehen einer Holzschraube im Holz hat.

As a general principle, a screwdriver needs to capable of fastening a screw!

But if you want to know if a screwdriver is really good, you should look our for the following:

1. Quality: Does the blade rust? Does the handle feel “good” or does the hand start to hurt after just a few uses?

2. Fit: Does the screwdriver optimally fit the screw? Does it fit in my hand?

3. Service life: Is the screwdriver capable of surviving the odd knock? Can I still rely on my screwdriver after a few months or is it already broken?

Is the plastic resistant to oil?

Screwdrivers also need to suit their application fields! An electrician's screwdriver must not conduct electricity! An electronics screwdriver must not destroy the board through the static charge of the technician. A screwdriver can’t slip out of the hand, even in oily or damp application fields.

Standard Phillips screwdrivers are characterised by a Pozidriv or Phillips drive, which can be associated with a corresponding screw profile.

The profile of a Phillips screw is made up of two perpendicular crossed slotted profiles. Compared to the classic slotted form, the screw properties are significantly improved, since the force application takes place at a total of four edges.

The profile of the Pozidriv screw can be seen as a further development of the Phillips screw profile. The user benefits from an additional cross, which is offset to the first cross by 45°. The additional cross is narrower and has a smaller depth, yet ensures extra stability and more winding surface.

In application, the Pozidriv profile must not be confused with the Phillips profile, since this will lead to extremely rapid wear of the fastening tool and screw.


Wiha slimTECHNOLOGY permits blades to be up to 33% slimmer by means of integrated insulation. Low-lying screw and spring elements in the critical working area can therefore be reached easily. The high-quality blade insulation ensures safe work on live parts up to 1,000 V AC/1,500 V DC. Additional safety is provided by the fact that every single screwdriver is tested in a water bath.

Screw contact is the term for the moment in which the screw head touches the work piece for the first time; in other words, the underside of the screw head comes into contact with the work piece.

The key width defines the distance (mm) between two parallel surfaces, and thus determines the size of the L-key.

Zuerst einmal ist die Auswahl des richtigen Schraubendrehers entscheidend. Für eine Kreuzschlitz-Schraube sollte zwingend ein Kreuzschlitz (Phillips)-Schraubendreher verwendet werden und keinesfalls ein Schlitz-Schraubendreher. So kann die Kraft besser auf die Schraube übertragen werden. Auch die Wahl der richtigen Schraubendrehergröße ist zu beachten: Ist der Schraubendreher zu klein findet er keinen Halt und schlägt den Kreuzschlitz aus; ist der Schraubendreher zu groß kann er im Kreuz nicht richtig greifen. Wenn Sie den passenden Schraubendreher ausgewählt haben ziehen Sie die Schraube mit Gefühl an.

Complete safety for the user is a paramount concern of Wiha when it comes to work on live parts. This is why Wiha complies with a wide range of standards and regulations, such as DIN EN 60900 for insulated hand tools.

In Germany and some other countries, there are stringent rules and regulations regarding work on live parts. It is only permitted to take place in special safety conditions. DIN EN I60900 is an international standard met by Wiha and their hand tools. Working under voltage should generally be avoided. Nevertheless, every single VDE tool manufactured by Wiha is individually tested for safety. After extensive testing, the tools are approved by our quality assurance. No tool leaves the company without being tested.

Wiha tests all VDE tools at 10,000 volts. This guarantees safe work up to 1,000 volts DC and 1,500 AC. In addition to individual piece testing, batch testing is carried out in the laboratory. Here, a range of features are inspected and assessed, including the durability of labels, checking combustion behaviour and holding force. Another voltage test is also carried out, in which the products are previously damaged in a water bath or heat chamber. Only if these tests are passed is the batch approved.

The VDE office awards the VDE mark for insulated hand tools (Verband Deutscher Elektroingenieure – Association for Electrical, Electronic & Information Technologies). Wiha therefore regularly sends products to the VDE office for testing and approval if the standards and regulations are observed. After approval, the VDE certificate is valid for five years. In addition to the testing carried out by VDE, a manufacturing site inspection takes place once per year. This is done to check whether the test regulations are being met in production and the laboratory.

With the hexagon L-keys, we make a distinction between brilliant chrome and matt chrome surface coatings. When it comes to TORX® profiles, L-keys have a manganese phosphate or titanium silver surface.

The matt chrome-plated surface offers ideal corrosion protection. The brilliant chrome-plated hexagon L-keys, on the other hand, boast a smooth surface, which provides less surface for rust and is therefore even more resistant to corrosion.

There is also a coloured version. The eye-catching colour serves to enable the quick identification of key widths and the location of the L-keys when lost in the machine, for instance.

For ideal corrosion protection, manganese phosphate L-keys are oiled after curing. L-keys with titanium silver coating are not. This makes oily fingers or re-oiling L-keys to maintain the corrosion protection a thing of the past.
