Bit Driver For Hex Screwdriver Bits

Quick Answer: The Bit Driver is a screwdriver handle with a hex socket in its tip that accepts interchangeable screwdriver bits, so one handle can drive slotted, cross-head, hex and star screw heads. A bit driver replaces a drawer of fixed screwdrivers for assembly and maintenance work.

One Handle, Many Screw Heads

Most handles of this type accept bits with a 1/4-inch hexagon shank, the size also used in most power-drill bit holders, so bits can move between hand and power tools. A magnet in the socket, or a spring clip, holds the bit in place. Whether this handle is magnetic, has a ratchet, and which bits come with it, is worth confirming before ordering.

The real advantage is that the correct bit is always to hand. Using the wrong screwdriver is the commonest cause of damaged screws: a slotted blade that is too narrow twists out of the slot, and a Phillips bit in a Pozi screw, which looks similar, rides up and chews the recess. Matching bit type and size to the screw, and pressing firmly into the head while turning, prevents most cam-out.

In a lab or classroom the tool deals with battery covers on a digital stop watch or a meter, the small screws of electronics and robotics kits, furniture fittings and apparatus maintenance. For pilot holes before driving screws into hardwood, a drill set completes the kit.

Care & Handling

Choose the bit that fills the screw head fully; a loose fit strips both bit and screw.
Press firmly into the screw while turning, especially with cross-head screws.
Do not use the driver as a pry bar or chisel, which bends bits and cracks handles.
Keep bits in their holder so sizes are easy to find and tips stay clean.

Applications

Assembling and repairing electronics, robotics and STEM kits
Opening battery compartments on meters, timers and data loggers
Fitting hinges, handles and brackets to lab furniture and storage
Routine maintenance of stands, clamps and equipment enclosures

Frequently Asked Questions

What is cam-out?

It is when the screwdriver tip rides up and out of the screw head under turning force, usually because the bit is the wrong type or size, or too little pressure is applied. It damages both the screw recess and the bit.

How do I tell Phillips from Pozi screws?

Pozi screws have small extra lines between the arms of the cross, at 45 degrees, and the matching bits have extra ribs. Using a Phillips bit in a Pozi screw, or the reverse, gives a poor fit and cam-out.

Can I use the bits in a power drill?

Bits with the usual 1/4-inch hex shank fit most drill and impact-driver bit holders. Use bits marked for power or impact use in those tools, since plain hand-tool bits can snap under impact.

Why do bits fall out of the handle?

The magnet or clip may be weak or clogged with filings, or the bit shank may be worn. Clean the socket and try a new bit; some drivers accept a bit holder with a stronger lock.

Is a bit driver suitable for electrical work?

Only an insulated screwdriver made and marked for live electrical work should be used near live circuits. A general bit driver is for isolated, switched-off equipment.

Which bits are needed for school kits?

Small cross-head bits are commonly found on electronics and robotics kits, with small hex keys for some frames and servo mounts. Checking the screws on kits you already use is the quickest way to decide which bits to keep handy.
