    Update - Works great!
  

*by L***S on Reviewed in the United States on March 25, 2019*

Update - The seller contacted me about the drill bits. They said I may have received a defective set.  They sent me a new set and it worked perfectly.  That is why I have changed my review from one star to five stars.Previous review - I tried to cut a single 8mm hole in a glass jar. All of the abrasive material came off the bit after about 2 min. Used water and still did not work.

    You get what you pay for
  

*by D***P on Reviewed in the United States on December 4, 2019*

Bottom line, they work but will not last...I guess fifteen diamond bits of any kind can only be so inexpensive and as compared to many, these are inexpensive but they are barely OK. As compared to another bit in the same size range I have, they are thin and clearly not made anywhere near as well.Most important is they will not last for many holes. I used one yesterday to drill one 'fairly deep' hole and I would say that at least half the diamond coating is already gone. This as compared to that other bit which has been used 30 or so times and still has lots of life.I also checked each drill bit and many are slightly out of round - The shafts are not accurately mounted. If you position the bit very close to the chuck, that will often make things somewhat better.So for one-off tasks and small projects these are OK but don't consider them to be a long term investment.

    Amazing Value; Cuts Porcelain, Ceramic, Glass, Clay With Ease
  

*by Y***Y on Reviewed in the United States on August 20, 2018*

I have recently gained an interest in planting succulents into different kinds of pots and this set of drill bits (hole saws) has tremendously helped me in drilling drainage holes on porcelain, ceramic, glass and clay pots.  It has been about a month since I started using the bits and they are still going strong.  I have drilled at least two hundred holes in different types of materials with more to go.  Here are some tips on how you can get the most out of this product.1. Wear safety glasses and gloves.2. Lubricate as you drill.  The holes will be cleaner and you don't have to worry about dust.3. Start at a 45-degree angle and let the saw cut into the surface.  As soon as the saw starts to cut, slowly adjust the angle such that the bit is perpendicular to the surface you're cutting.4. Apply very little force.  Let the saw do the cutting.5. Take your time, start slow and be patient.  You're working with material that could potentially break and may cause injury.6. If you have a variable speed drill, start at a slow speeds.  Only increase speed when you become comfortable with the process.I have purchased similar saws from Harbor Freight, QEP, Milwaukee and Bosch and this set easily beats all of them in terms of value.  When used properly, they will last longer.Do keep in mind that these are bits.  Just like other bits, they will wear out with time.I purchased this product when there was not a single review.  I'm hoping that this review will help other Amazon shoppers.  I will be purchasing this again when my set is fully spent.
