Is it safe to use short bits (from manual screwdriver) with electric drill Ryobi R18PD3? Length of the hexagonal part (that fits into the drill) is 1.5cm. Original bits seems to be a bit:) longer.
It's reasonably safe, but there's a small risk that the bit may slip into the chuck at an inconvenient time,
Sockets are available to to hold these short bits improving reach and removing the risk of slippage.
Sometimes the bits sold with cheap manual screwdrivers are of poor quality (like made of soft steel)
