These drills are very aggressive. So be careful when drilling in some woods as they will retreat very quickly and blow out from the other side. say they are amazing. very sharp and they do the job perfectly.
I bought it by mistake, thinking that they were long. I'm glad I got these instead, not only do the bits have more hitpoints, but their short length allows me to get into tighter spots! Because of their bite, I hardly use any force when drilling in wood.
When new it will feed into wood It can be bad because it puts a challenging slot on the drill bit Extra don't hit the hidden nail The cutting blades knock very easily Don't expect that it lasts a long time very good for the money and the size is perfectly suited for 2x4
Great bits for drilling but you can't read the markings on which size is which. The size is printed in small black letters on the refill pack. Outside of bright sunlight and perfect vision it's impossible to read, although they are brand new can't imagine they will last next week and still be readable. Set with case.
I will never buy a wing drill again. They pierced the tree like its (almost) butter. If you have a lot of holes to drill, it will save you hours and hours. I mentioned that your hands will be grateful to you and you will have strength for any job that holes have been drilled for. Tool life, I use Dewalt cordless drills and save time by not having to change or charge batteries. Try them, you will be amazed.
The great thing about these bits is that they are very aggressive and cut fast. The bad thing is that they are very aggressive and if something goes wrong these 3 spurs will attach themselves to the cutting flutes, stop the drill immediately and your drill will try to rip off your hand. After spending some time drilling through joists with the 1 1/8 bit, where I often hold the bit at odd angles, I went back to the spade bit. It's not that fast, but I didn't have to worry about breaking my arm.
I have some self-tapping bits, but I needed short ones for hard-to-reach places. Even a new (sharp) 3/4" drill bit was hard to get through the pine posts with a powerful cordless drill! My guess is that the thread is too long and biting off too much at once. I'm not sure that's helpful considering the number of times I've had to stop, back up to get a punch out, and start all over again. I suppose I could use this as an excuse to buy a more powerful drill, but then it might not fit in the space
Fully threaded tip allows the drill to self-advance for easier drilling
If you can get through bare wood without nails or screws, these drills are a godsend. Be careful if there is something on the other side. These nozzles are SUPER aggressive and barely penetrate wood. Unfortunately, when they hit a nail or screw, it's a little more than they can handle, as they make very smooth holes and very quickly. My 7/8" bit was gnawed on by a nail and now the threads on the tip are broken and the edges of the cutting faces are chipped beyond repair. And that was from being
Three cutting edges for faster, cleaner drilling, less chipping and longer drill life
I've used it to drill about a hundred holes in power poles during the reconstruction. They worked well for about the first two holes but seemed to dull very quickly. I was only halfway through a lot of things, so I started carrying a very small half-round file in my pocket to touch up the edges from time to time. I didn't let these tips get too hot, but they didn't hold the edge well at all. In addition, part of the quick-change shank of two bits broke off during use. ) and they were amazing…
