## Customer Reviews

### ⭐⭐ 







  
  
    Not my best purchase
  

*by R***E on Reviewed in the United States on February 1, 2020*

The only bit I have used so far twisted up after a couple of holes.  These bits are obviously created by twisting the shaped metal into a spiral drill bit.  This one untwisted itself.  They might work better soft dried lumber.

### ⭐⭐ 







  
  
    Soft metal. Will not hold shape.
  

*by M***T on Reviewed in the United States on February 25, 2020*

The steel used is soft and weak. The one I used twisted itself in the opposite direction half way up the bit. Sent it back.

### ⭐ 







  
  
    Would NOT recommend.
  

*by G***R on Reviewed in the United States on March 19, 2021*

Opened the package as soon as it arrived.  Everything seemed fine.  Put the drill bit in my drill press and turned it own and realized that 1.  The bits are not very sturdy and 2. every bit was wither warped or bent.  Ever try to drill a 4mm hole with a bit that wobbles about 8 mm?
