​I've always had my tools supplied to me so can't comment on price but the bacho 1/4 and 1/2 inch drives sets are great. Mine are both 9 years old now with regular industrial use and they're still spot on.

I would only use a 3/8" drive for light work on cars and motorbikes. You really want 1/2" drive which will cover all the bases.

I would only use a 3/8" drive for light work on cars and motorbikes. You really want 1/2" drive which will cover all the bases but at £17.00 it's worth a go. I still got my socket set from over 30 years ago.

Of those two, go for 3/8" for general use. This should be ok up to a 12mm bolt, which is a 19mm socket. If you're considering use on cars, then for most things 3/8" will still be ok, but if you get a bit more enthusiastic, there are some things which you would need to go to 1/2".

In short, if you want to keep to one size, light use (bicycles etc) 1/4", general use 3/8", more serious car use 1/2". If you're happy to have two sizes go for 1/4" for small size and 1/2" for strength.

​It's the size of the drive.

​It's the size of the square drive across flats.

True, got this set, but rarely use it because of that :disappointed:

Great product, well made, great size to do most DIY jobs on the car. 3/8" is the most versatile socket set that you could have! Initially was worried about the sockets not being hexagonal, but on service parts (oil sump plug, oil filter) they are strong and well built that stripping nuts wasn't as issue

In a nutshell, ​no. The Bahco s330 3/8 set are 6 point wall drive and the bahco ratchets are considered better quality than the halfords ones. That being said the bahco set is twice the price of this one. This halfords set is very good value for money.
