What it is
Torx bits Fervi. Key specifications: is50tx15 1,38, is50tx20 1,38, is50tx25 1,38.
A screwdriver bit is an interchangeable driving tip, Phillips, Pozidriv, Torx or hex, for fitting to a screwdriver or bit holder with a hex drive.
What it is for
Used for repetitive screwdriving into wood, metal and plasterboard, where torque and consistency matter.
How to use it
Choose a bit that exactly matches the screw's recess type and size: PH and PZ are not interchangeable. Insert it in the chuck or magnetic bit holder and drive the screw with the tool in line and steady pressure. With impact drivers, use impact-rated bits, and replace them as soon as the tip becomes rounded.
