What it is
The DeWalt DT7997T-QZ set contains 5 Impact Torsion bits with a Phillips head and a length of 57 mm, designed for use with impact drivers. The extra length makes it possible to reach screws in recessed or deep positions, while the torsion construction is designed to absorb the torque peaks typical of impact driving.
The bit set is a pack that brings together screwdriving bits of various types and sizes, often with a bit holder or socket, in a pouch or case.
What it is for
Used for repetitive screwdriving into wood, metal and plasterboard, where torque and consistency matter.
How to use it
From the set, choose the bit that matches the screw by type and size, fit it to the screwdriver and drive the screw in line. After use, put it back in its place in the case. Replace worn bits.
