My reference point for these FTG USA wood countersinks is the DeWalt set that I have been using for quite some time and I am a fan of these FTG USA drills. I like countersinks with FTG bits because of the sharper angle that goes well with the angle of the screws I use. There is nothing wrong with the DeWalt set just to note the difference here and that the FTG angle suits me. There is a picture showing the difference. FTG bits are flat on each side of the bit to prevent the countersink from rotating in the shank, so it's very nice. The bits are pretty sharp and eject chips really well, and one thing the FTG bits have that the DeWalt set doesn't have is a depth gauge. This helps me to make many identical and repeating sinkholes in a row. With the DeWalt set you have to try to stop in the same place, but you never succeed. With the FTG USA depth gauge I get a perfect hole and sometimes a burn mark from the gauge which is ground off immediately. Just touch the 120 grit to make them look perfect. All beats are nice and straight. Funny story: I have never used a DeWalt #10 bit and when I pulled it out to compare it to an FTG #10 I found that the DeWalt bit was badly bent and unusable, so it means buying a recognized brand not always quality, FTG #10 bit The 10 in my set was perfectly straight as were #8 and #6. Both sets are within 9 cents of each other at the time of this writing, around $20, so someone might be tempted to go with the DeWalt set because of brand recognition. My FTG set is probably better than my DeWalt set just for the #10 bit issue, then add a sink gauge and I think the FTG set is compared to the DeWalt set I own, very much. FTG USA countersinks do not disappoint and I will definitely be using them in my shop, give them a try.
