What it is
The Phillips bit inserts C 6 Series CB/250 Unifix are screwdriving bits with Phillips drive and C 6 shank, designed for use with compatible screwdrivers and drills. The Phillips profile ensures good centring on the screw head, while the C 6 shank ensures quick, stable coupling to the tool. The product complies with CE marking under the EU directives.
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.
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.
