Adjustable Wood Countersink Drill Bit Set5 Pc Countersink Drill Bit #4#6#8#10#12 Tapered Drill Bits for Woodworking

I'm building a new deck and bought these to counter-sink & pre-drill the holes on the end of the deck boards. I did end up using 1 size smaller than the suggested size on the packaging mainly because the recommended size caused the head of the screw to go deep into the wood and I was afraid it may not hold as the boards dried out and warped, etc. For durability, I used the same bit to drill over 275 holes and it is still sharp enough to keep drilling. Definitely worth the money and comes in very handy.

this product feels good for the money spent. its something small im working on so dont need to spend a lot and this item really came up very good to work with.

Over all it's well build, except the big collar can't fit the #12 bit.

Use for carpentry

Very easy to use.I've used them quite a bit, but one of them seems to have dulled badly.So not really good value for money.

Ordered these on whim, and have not been disappointed. They are sharp, accurate and durable. Was working with some very soft wood that is known for splitting, and didn't split one board using these bits. The was still using the first one from the package until I knocked the drill off the ladder and it of course landed square on the point on concrete. Bent the bit to unusability. Tried to straighten it, but it never ran true. Nice think is you can remove the countesink portion of the bit and save that for something else, or installing onto another regular bit. Love them so much, I bought another pack to keep on hand, and to kit out my other tool bag. You won't be sorry.

I got to say if you're on a budget a little bit of money to only spend on your woodworking a little bit each month or each week however you're if you're starting out these b**** all right good set of bets for the value but they do doll and they do break very easy if you're going into hardwood and if you're like me and you do woodworking what I call the hybrid way and you do power tools and hand tools one thing you I don't believe in is using battery operated so if you're going to use these with a power drill a corded power drill if all possible make it a very little speed so you can slow it down especially in hardwood otherwise you will snap that and they don't snap at the bit directly they snap between the truck and the countersinks that is my only complaint otherwise they are good the value when you're starting

The collar is sturdy and very durable but the problem is with the drill bits. They're tapered so it's not like it's easy to just switch them out with regular drill bits so I needed to use them but they are extremely brittle. I'm using these on Yellow Pine and the bits snap off on the tips and even at the base by the collar with ordinary use. Again the collar structure is very tough and durable but the bits are trash. Buy separate bits or buy another kit.

Les mèches brisent facilement et sont trop flexibles! 🫤
