Bits and Bit Holders for Drivers and Hand Holders

The bit must fit the screw recess exactly. The most common are PH2 and PZ2 for wood and drywall screws.

25 mm bits work with a holder, while 50-150 mm bits reach deep screws. A 1/4" hex shank is the standard.

For impact drivers choose bits marked impact, which do not break under load.

S2 steel bits are tougher than ordinary CrV. Read hand tool materials, hardness, coatings and ergonomics.

Do not use a worn bit that cams out of the recess. Read how to use hand tools safely.

Keep bits in a box by size so they do not get lost. Read how to maintain, store and organize hand tools.
