Long drills
These are great, really useful and good range of sizes. Very pleased.

Ideal long shaft drill bits.
These are ideal for those cases where you need to drill clean through one bit and into another ! In my case I use them for model making (generally the smaller sized ones) where you need to pin parts together. For this they're more than long enough, fit well into a twist drill assembly and are nice and straight. The second comment may seem odd but with long shank bits any variance in straightness ends up as a huge wobble at the pointy end ! They're well priced and of good quality

Long Drills
Sometimes, you just need a bit of extra length. These are good for that.

Happy to recommend for use of soft wood
Already used a couple of these and they are fine so far. Only used on soft wood but they were okay with that, cutting into the wood about 100mm no problem. Pull out frequently to clear the flutes and then press in again. Easy peasy

Ideal drill bits where regular ones aren't long enough or the chuck is obstructed.
First use was to use the smallest 2mm drill to make pilot holes to fit a wooden door to an integrated dishwasher. Regular drill bits failed to reach right through the alignment holes in the dishwasher door without the drill's chuck fouling but this long bit worked a treat and 5 minutes later the door was fitted securely and perfectly square. I have also used the 6mm to drill through a studded door frame to take a co-axial TV cable through from dining room to study. I wouldn't exert too much force on the smaller bits as they could snap. At this price they are not designed to be heavy duty.

Does the job but not sure how durable
Not sure what I was expecting with these but they do the odd job I brought for. However, they do seems to be quite bendy so I can't imagine they are that durable with regular use.
