This isn’t a carbon steel product, so I suspect it won’t last as long as the CS versions - but it did penetrate 4x4 pressure-treated posts.

Used to drill holes in 4x6x16 treated lumber to drive #4 rebar in

I have a lot of work to get done around the house (real fixer-upper situation), so I've been going through tools like crazy. These have been a real workhorse for me, but I want to warn people: don't use this on harder wood or on thicker bits of soft wood. You'll be in for a lot of heartache and extra work tending to your drill bits. However, this was perfect for some of the smaller holes that I needed to drill, and a real peach on the softwood I was working on. I'd recommend this set as a secondary set to go along with your better drill bits. It's inexpensive enough that it's worthwhile to have it around for lighter jobs.

Did what was bought for.

Thanks ,

Love having the variety of sizes to find the right bit for the right job. The canvas bag having individual pockets is nice to keep them organized.

Update: these are trash. They are great for a single pass but dull extremly fast. So fast that they are useless after you drill a couple times. They are made to look good, last just long enough to get a good review and squeeze past the return window. Then they are trash. Original review: Theses do what they are meant to do. The negative is that the screw end, that is supposed to help pull the bit into the wood, wears out almost instantly. On one of them I had to go through a 6 inch thick beam. The screw was practically useless after that. I was forced to use a lot of pressure and even rock the bit slightly to get it to bite and finish the whole on the next one. I probably would give them a two or three star but the price is good so it's a case of you get what you pay for. I still use the so they aren't useless just not as effective as other wood boring bits I have.

GOOD

Used the 3/4” bit to drill through landscape timber and only made it through 12 before dulling And burnt. When first used it though it was great!

I have a couple of old school braces (hand operated drills) that use this type of bit that have been hanging off a garage shelf since I inherited them 20 years ago. I remember that type of drill being used a lot when I was a child. I saw these and thought they would be great to have so I could use my old school tools. The results were really disappointing. I tried to drill through a 2x6 the long way with the smallest bit and didn’t get much more than a couple of inches into it. The end of the bit had pine built up in the cavity where the bit needs to be pulled in and cut the wood before the chisel planes away the material inside the hole and augers it away. I was ready to send them back and rate them as one star. To be fair, I tried using my 18 volt 1/2” Makita drill and had much better results. Better, not great. The holes (I only tried up 1/2” so far) were clean and smooth when I made it through. There were times that I got better results in softer wood with higher speeds. I am pretty sure that a small pilot hole will speed things along with a small pressure on the bit. When drilling slows down, pull the bit and clean the build up at the end. A toothpick worked fine for me. Next time I use one, I’ll try wiping the bit with some light oil on a rag to reduce friction. These have enough resistance to cutting and friction that batteries won’t last long. I doubt my Makita will get the job done with the larger bits and I’ll have to go to a corded 1/2” drill with a side handle when making big holes. These bits are pretty inexpensive and my expectations should be based on the cost of the bits. For the price, these can do a good job if you have a little patience and compensate a little. I’ll call them four stars. If the price had need $100, they would have gone back right away. If I want to use my old school drill, I’ll need to keep my eye open for some bits closer to my age.
