Tried them for drilling through a window and through a Weber bbq, as well through inox steel. The performance is incredible. Very recommended!

OK

Had these for a few months and haven't had any issues. Nothing had broken and they still seem very sharp. The case is compact and easy to use

I absolutely love these. What other do bits can't to, these can.

GOOD PRODUCT

Price is right. Nice case quality set.

Recently I had to add an attachment to the tractor bucket that required 8 holes to be drilled. My plan was to use a bit to get the hole started and then use a step bit to finish the holes. I must say that I began the job without any cutting oil and after about 30 minutes, I only had very hot drill bits and only about a hole and a half completed. I chucked those bits and then purchased these. A week later, I tried this with cutting oil and the new bits and it did help a lot. I was more able to get the bits to bite and tap the holes. However, it was not magic. I still had to work pretty hard, after the first hole which went fairly easy. The next holes got progressively more difficult. In other words, the bit dulled fast even with a very liberal use of cutting oil. They oil still got hot enough to smoke and the bits did get red hot at some points. I tried multiple methods and speeds to get these holes done. I used a lot of oil. So, the bits worked but not as good as folks were saying they did at least not for me. I would actually rate them a 3.5 to 3.7 if able to give partial stars. Hope that helps.

They are worth the money

Haven't broken one yet.

Price ok but the 3/8 drill bit broke the first time I used it.

Lost the key to my lock. Using these bits, drilled right through the metal like it was nothing and able to break the lock.These are a must have for bit sets. I’ve had many sets, but these are worth their value for hobbyists like myself.

Nice quality

El juego de brocas lleg completo sin ninguna novedad, son de buena calidad y el precio est bien, eso s es mejor comprarlo cuando est en oferta

Good casing

Great set to have on hand. However, I thought I was buying new and one of the bits had clearly been used. There was still drywall in the grooves :/Needed the set for a project so I didn't return. No issues so far

Trabajan muy bien con el metal y se siente su calidad, seguramente me durarn mucho tiempo

they work

Thank you

Great price for these quality drill bits. I haven't broke one yet and they are used almost daily.

Quality product requires a chuck, shanks are not hex. no problem, just point of information
