Quality bits and solid durable case
Although I already had a range of flat bits I bought this set to cover the sizes I didn’t have and more importantly for the case as I find it a pain to have to sort through a bunch of bits looking for the correct size. The bits are of excellent quality and sharpness as most reviews have indicated. The shafts are thick and strong with no danger of bending, even if given some abuse. The case I received was black and yellow rather than yellow and black (see pic), but apart from that identical to the product images. The case comes with some thin clear plastic retainers which support the bits at their tip as well as some black point protectors (which are just a lose fit). I think these are both just transport packaging as with them in place it is awkward to remove the bits so I dispensed with both and they still stay firmly in position during transit from site to site and are much easier to remove. There are several extra positions within the case for extra bits which I will no doubt fill at some point. All together a very good buy at a reasonable price considering the quality.

Dewalt quality
This is a little bit like re-inventing the wheel. I'm guessing that Dewalt R&D Dpt looked at a spade drill and wondered how they could improve it. And indeed they have. The shank is thicker (as a lot have stated) removing the risk of twisting the bit. All spade drills are made with a front rake clearance to enable the bit to cut. Dewalt have gone better by adding a top rake angle as well. The final touch is a slight chamfer on the corner of the bit. Absolutely fantastic product to use and comes with a very practical and strong case. They work like a dream and if I ever need to replace them it will be with the very same. If I was to be very picky and find fault it would be to say that they are a little difficult to get in and out of the case but it is such a small point and I still have to give it 5 stars.

Great Drill Bits, Awkward Case
Drill bits are quality and do and excellent job leaving a clean cut around the hole. My only criticism is aimed at the case. Whilst the case is strong and tough with a good closing mechanism, the bits are secured tightly within and are a real fiddle to remove and replace.

Great quality for the price
Very well made for the price here on Amazon you can't go wrong I use these for construction work (I'm an electrician) and find these bits are much more robust than your ordinary cheapo bits which may I add are a couple of pounds each anyway it's a no brainer really the cutting edge lasts a long time and with it being pretty thick metal they can be sharpened too

Superb
Really impressed with Dewalt over these bits. These and their Brad Points are the best woodworking bits I've ever used. Very happy with the quality of the construction, these are incredibly strong bits, no flexing at all. Hex shanks are lovely. Tip protectors are a nice touch. The box is good, but I would have preferred bespoke inner mounts, these bits do deserve them. In use they cut through all wood types with equal ease. No splinters, clean cuts. Lovely. I agree with everyone else over these. Very highly recommended, if you're in the market for some flatbits then look no further.

Does the job well with no fuss.
I've been using these to drill bolt holes through 4" treated fence posts and they are excellent. They drill straight, are fast and have stayed sharp. The case is tough and there are a few spare spaces in it for my other odd sized flatbits that would normally rattle around in the bottom of my toolbox. I'm very happy with this DeWalt purchase.

Best Spade Drills I have Used
I always seem to have a stack of old spade drills around the workshop but with varying degrees of sharpness so decided on buying this set to place in my grab bag. Not the cheapest but I guess you get what you pay for as they seem to be very good indeed. They are extremely sharp and cut perfectly. Hopefully the good quality case will also mean that no longer will I be able to find every size except the one I need. I hope this review helps and if it does please click the 'helpful' button so I know I have not been wasting my time. Thanks.
