What it is
SQ2 bit, 155 mm (set of 5), Makita 191V04-6. Key specifications: screwdriver socket SQ2, pieces per pack 5, hex connection 1/4".
Screwdriver bits are interchangeable Phillips, Pozidriv, Torx, hex or slotted tips, with bit holders and right-angle attachments, for fitting to drivers and screwdrivers.
What it is for
Used for repetitive screwdriving into wood, metal and plasterboard, where torque and consistency matter and for installing plasterboard partitions and suspended ceilings.
How to use it
Match the bit to the screw recess by type and size, without confusing PH and PZ, and lock it in the bit holder or chuck. Drive with the tool in line and steady pressure, using the clutch so as not to strip the screw; in tight spaces, fit a right-angle attachment. With impact drivers, use only impact-rated bits, replacing them as soon as the tip is worn.
