Adjustable Wood Countersink Drill Bit Set #4#6#8 with Tapered Drill Bits for Woodworking

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 use it for countersinking my wood fscrews and by putting a wood plug in the countersink hole, makes it a very smooth and more professional looking project. Would buy it again

Works as expected

They just work

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.

Works really good I'm happy with this set a good addition to my woodworking drill bits

The depth stops will break if you look at them, disintegrate if you use them. The bits are ok and do what they are supposed to do.

Spend a little more money and get something made of quality materials. This broke after about 18 drillings, in normal pine wood, with a regular electric drill, and proper use. First the 1/4" Hex shank came loose, I guess there's a flat part that got rounded out by the torque, so it couldn't catch the drill bit at all anymore and just spun freely. I was able to take that hex shank piece off and just use the drill bit piece since it has a little bit of a flat side. I even took off the counterbore attachment to hopefully decrease the torque I was putting on it... I drilled like 4 more holes but then the tip of the drill bit cracked off. I wanted the counterbore holes anyway because I'm making furniture and don't want to see screw heads. I was careful about keeping the drill at 90degrees, and the wood wasn't anything hard - the store's cheapest option.

Son muy resistentes para todo tipo de material, madera, laminados, Mdf, etc., las recomiendo, pronto compraré otras.

Les mèches brisent facilement et sont trop flexibles! 🫤

Buen producto, hace mas rápido y fácil las uniones con tornillo en madera.
