A bit-holding screwdriver uses interchangeable screwdriver bits in one handle. Match the selected bit to the screw‑head interface and size.
Typical applications
- A generic bit-holding screwdriver can be used with different bit profiles to address various screw-head types. It is important not to use a bit on an interface it does not match.
Advantages
- Some multi-bit drivers include magnetic bit retention and a storage compartment in the handle. When choosing a driver, check for these features rather than assuming they are present.
Specifications to check
- Check which bit profiles and sizes are supplied with a multi-bit driver. The number of included bits alone does not identify their interfaces.
Limitations
- Interchangeable bits do not make near-fitting screw-head types interchangeable. Use the correct type and size rather than forcing a mismatch.
Buying considerations
Choose a driver with an intact handle and undamaged tips. Store drivers so the correct one can be selected easily.
Safety & limits
- Secure small work before driving screws and keep hands clear of a slipping driver. Never use a screwdriver to test whether a circuit is live.
