amoolo Impact Drill Bit Set, 1/16"-1/4", 16pcs

Long lasting for steel framing work. A++++++

These came as described. From other reviews, I'm not the only person who seems to break a lot of 1/8 inch bits

First, the reason for knocking off one star was that the drill bits come with a coating of oil on them that had to be cleaned with mineral spirits before they could be used. I do understand preservative reason for the oil but when using these in woodwork, the oil can be a real problem. I purchased these for use in a drillpress where the 1/2" chuck cannot clamp on the smaller sizes of the bits and buying a smaller adapter chuck to fit into the big one was more costly and less reliable than purchasing these hex drive bits. I also use these in an angle adapter that has hex drive to get into tight spaces to drill small pilot holes for screws and these do the trick. You will not regret pruchasing this set of bits.

Excellent product

The amount for the price is perfect. I use these for work. I purchased the set a few months ago and I am still using the first drill bit. Good quality.

Great product, very useful!

They are what I expected, drilled 3 holes in thin metal and they started smoking from getting dull. They are cheap, but I knew that going in, probably be best for drilling in light wood.

I’ve only used one of the ten bits so far, but no complaints here. Admittedly, only wood so far. I haven’t tried metal yet, but have no reason to think they won’t work.

سيئ

Excelentes la verdad muy buenos materiales duraderos

Appear to be a good quality. They are true as fas a straight, no wobble.

It comes with a case. All the drill bits are kept together. A reviewer wrote they weren’t very sharp. They are sharp and if you let them cut instead of forcing them they should last. I used them to cut wood and drill metal. These are for a hobbiest, not for an industrial setting.

Penetra el metal como si fuera madera y con una sola broca he realizado mas de 50 perforaciones en perfiles de 3 mm de espesor además su mango hexagonal evita que la broca deslice en el mandril del taladro. Increible producto.
