- 867/4 IP TORX PLUS® bits, 9 IP x 89 mm
Product description
High quality bits for recessed TORX PLUS® screws. TORX PLUS® profile: in comparison to normal TORX® profiles, the enlargement of the 6 torque-transferring flanks between the tool and the screw is effected by means of an ellipse-shaped profile design and not a circular one. This means that the power applied when screwdriving is spread over a larger area. Higher torque is transferred and the service life of the screw and tool is also enhanced. Tough viscous for universal use. 1/4" hexagon, suitable for holders as per DIN ISO 1173-F 6.3.

Design
Features and benefits
- 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 centre-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.
- Tough Wera bits prevent the tip from breaking prematurely. Z-bits usually are the bit for universal screwdriving applications.
