Review: 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.
Review: 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.
