Works amazingly well with drill press parts and accessories

I've only used a 5/8" drill bit so far but it holds up very well. After about 50 holes in 4 1/2" thick concrete, it still performs very well. It's not as sharp as unused bits, but wear is minimal. I soaked the bit in a bucket of water for about 10 seconds after each hole fall, which prevented overheating.

Cons
  • Drill Bit Pack

The bits are ok, the case is bad

The bits in this set are ok. Haven't used them long enough to comment on their durability, but so far they seem to be doing the job. The plastic case is pretty poor and doesn't hold the bits very well. When this product arrived I could already hear all the parts hanging around, none of them holding as tightly as they should in the case.

Cons
  • later I will add

The quality of the case for the organization.

I didn't like the tool kit case. I received a sealed box and when I opened it all the parts fell out. Put them back in the case only to have them all fall out after being transported to a new location. The case is useless, you might as well throw all the bits in the bag as they won't stay in place in the case and there is no marking where the bits should be in the case. Can't comment on the quality or durability as I've never tried any bits, couldn't get over the bits falling out every time I…
