The Wera Tools 05345019001 is a set of high-quality TORX PLUS® bits designed for professional use. These 867/9 C IP TORX PLUS Bits have a 4 IP size and are 64 mm in length, making them perfect for fastening TORX PLUS® screws in tight spaces. The hard design of these bits ensures they can withstand high levels of torque without breaking or bending.

Additionally, the 4 mm halfmoon drive of these bits makes them compatible with Wera's connecting series 9, allowing for direct power tool insertion. This feature makes it easy to switch between manual and power tool applications.

Overall, these bits are a reliable choice for professionals who need to work with TORX PLUS® screws regularly, and their compact size and robust design make them an ideal addition to any toolbox.

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.
