Wera Kraftform Kompakt 900 Set 1 — manual impact screwdriver with a switchable hammer function and 18 bits
19 piecesSwitchable impact functionApprox. 25 Nm loosening torquePound-thru blade
The Wera Kraftform Kompakt 900 Set 1 (part number 05018110001) is a 19-piece interchangeable-bit screwdriver set with a manually switchable impact function, built for one job in particular: loosening stubborn screw connections. The 921 Kraftform Plus impact screwdriver converts a hammer blow into rotary movement, generating roughly 25 Nm of loosening torque, and switches back to a normal screwdriver when the impact function is not wanted. Eighteen dedicated 70 mm impact bits cover Phillips, Pozidriv, TORX, Hex-Plus and slotted. Typically in stock with fast delivery across Cyprus.
Compatibility — check before buying:
This is a loosening tool, not a torque tool: the roughly 25 Nm figure is the loosening capability produced by a hammer blow, and Wera publishes no accuracy figure and cites no torque standard for it. Use only the supplied S-series impact bits in the 921 — ordinary or torsion bits are not built to take hammer blows. Note that Wera’s own web pages corrupt the contents list by merging the quantity digit into the size, showing the Hex-Plus bits as 13, 14, 15 and 16 mm; they are 3, 4, 5 and 6 mm. Nothing in the set is insulated or VDE-tested, so it must never be used on live parts.
Best For
✓ Seized, corroded or over-torqued screws
✓ Automotive and machinery disassembly
✓ Maintenance work where a driver just cams out
✓ Painted-in or thread-locked fasteners
✓ Workshops that keep rounding screw heads
✓ Technicians who want one tool for both jobs
Key Features
Switchable manual impact function
A hammer blow on the end cap is converted into rotary movement, delivering approximately 25 Nm of loosening torque to break a seized screw free. The function switches on and off, so the same tool works as an ordinary screwdriver for the rest of the job.
Pound-thru blade and hexagon bolster
The blade runs right through the handle, so Wera can state the hammer blow is transmitted without loss rather than being absorbed by the grip. A hexagon bolster takes a size 13 open-end spanner when even more turning force is needed.
Eighteen dedicated impact bits
S-series bits made specifically for impact screwdrivers: Phillips PH 1 to PH 3, Pozidriv PZ 1 to PZ 3, TORX TX 15 to TX 40, Hex-Plus 3 to 6 mm and slotted 4, 5.5 and 6.5 mm, all 70 mm long. Wera specifies them as specially hardened and extra tough to resist premature breakage.
Kraftform Plus handle in a textile box
The multi-component Kraftform Plus handle has a non-roll design so it stays where you put it, and the set travels in the 9467 textile box with a hook-and-loop closure, rubber retaining loops and a fleece zone at the back.

Frequently Asked Questions
Singular Expert Insight
A manual impact driver is one of those tools that sits unused for months and then saves an afternoon. The reason it works where a good screwdriver does not is that the hammer blow applies axial force and rotation at the same instant, so the bit is driven into the recess exactly when the turning force arrives rather than climbing out of it. That is also why the dedicated S bits matter: this is a shock load, and an ordinary bit will eventually shatter under it. Two things to be clear about before ordering. It is not a torque tool, and the 25 Nm is a loosening figure with no standard behind it; and it is not insulated, so it stays away from live work. Note also that Wera’s own pages misprint the hex sizes, which several resellers copy. Browse our Cable Tools and Testers range for the rest of the hand-tool line-up, or the wider Cables and Accessories section for installation material.
Buyer’s Guide
Buy it if
You regularly meet seized, corroded or over-torqued screws that cam out under a normal driver, and you want a switchable impact screwdriver with matched impact bits in one box.
Skip it if
You need controlled tightening torque, you need insulated tools for live work, or your fasteners are small enough that a hammer blow would damage the assembly.
Also consider
The Wera Kraftform Kompakt 900 Imperial Set 1, which swaps Pozidriv for square drive and uses imperial hex sizes, or the 921 impact screwdriver on its own if you already have S-series bits.
