Manufactured using most modern production technology in the world's largest cold forging hand tool factory.

The ratchet - the key item:
Made from CrV steel in one single piece. Hardened and with perfect toothing: several of the 52 teeth engage simultaneously for transmitting extremely high torque. Quick release mechanism: releasing sockets at the push of the button. Optimum surface protection: twice nickel plated then chromed in matt finish. Non-detachable handle made from oil and acid-resistant TPR (thermoplastic rubber) with hanging hole.


The PROXXON driver system:
The driving force is applied to the flanks, not the corners. This ensures high power transmission without damaging the corners of the nut or bolt.



Screwdriver bits:
With CrV socket .
The drive bits are all an optimum combination of chrome-siliconmanganese-molybdenum steel .


All bits and accessories are forged using 31CrV steel. High carbon content to ensure consistent hardness. Deep, uniform forging is fully guaranteed on the hex. drive side to ensure that protruding studs do not present a problem. Thin-wall construction for better access while maintaining strength for heavy work. Lead-in chamfer allows socket to slide over nuts easily. Machined fits on drive square allow ratchet to arrest properly. Beginning with the 19mm size the outer diameter of the sockets is reduced on the drive square end for improved handling . Optimum surface protection: Double nickel-plating and single mattfinished chrome-plating.


Socket sizes easy to read due to laser marking!



Screwdriver handle with 1/4" square drive. 1/4“ rear end connector to fit a ratchet or a T-bar.


Quality at its best:
Highest quality, exceeds DIN/ISO requirements for hardness and maximum torque. Individual size tolerances are all well within the prescribed norms.
