These bits have a 4mm halfmoon drive and can be directly inserted into a power tool for efficient and easy use. Additionally, they are compatible with Wera connecting series 9, making them versatile and convenient to use with other Wera tools.

Overall, this set of TORX PLUS bits is a reliable choice for professionals and DIY enthusiasts looking for high-quality bits to help them get the job done efficiently and effectively.

Compared with the "normal" TORX® profile, the elliptical instead of circular profile enlarges the 6 flanks that transfer torque between the tool and the screw. This means that the force applied when screwdriving is spread across a larger surface area. Higher torque is transferred and, in addition, the service life of the screw and tool are lengthened. The so-called center-lock screws on cutting tools represent a typical use of this type of screw profile. The thermal influences on such holders for carbide insert tips often "bake" the retaining screws so firmly that it is important to have a profile that considerably enhances the loosening torque capability of the screws. For this reason, a torque-stable screw profile is necessary to avoid any possible damage to the screw and to exclude the possibility of an otherwise costly machine downtime.
