What it is
The DeWalt DT71521-QZ bit belongs to the Impact Torsion range, developed to withstand the stresses of impact drivers. With a Pozidriv PZ2 profile and a length of 25 mm, it is supplied in a handy pocket case that makes it easy to store and carry, so you always have it to hand during your work.
A screwdriver bit is an interchangeable hex-shank bit fitted to a drill driver or bit holder for driving Phillips/Pozidriv, Torx, square or slotted screws.
What it is for
Used for repetitive screwdriving into wood, metal and plasterboard, where torque and consistency matter.
How to use it
Choose the exact drive type and size for the screw and insert the bit in the magnetic bit holder or directly in the chuck. Keep the bit aligned with the screw and push in line, so it does not cam out and damage the recess. With impact drivers, use only impact-rated bits.
