## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Good enough for most of my needs.
  

*by A***R on Reviewed in the United Kingdom on 6 September 2017*

Like someone else has already pointed out, they don't always do the prettiest job. Somethings they will chatter or vibrate a little, which leaves slightly squ-ircular countersink (which isn't a big problem, it's just a bit ugly). I'm certain my clapped out, mesolithic drill-press is half of the problem there, but that issue is only something that only seems to happen with these countersinks. 9 times out of 10 going slower and using a generous amount of lubricant helps - in softer materials (wood, plastic, etc) I sometimes even run them backwards once I'm getting close to the final depth.All that said, I would recommend them. I haven't been able to get perfectly consistent countersinks from them, but for the price they're pretty good. Just take it easy and cross your fingers if you're using them for anything that's got to look pretty.

    Appears to be very good set
  

*by R***B on Reviewed in the United Kingdom on 20 July 2019*

Haven’t used all of them yet but the ones I have worked fine, time will tell about the durability of the bits, I’m not using them all the time so it may be some time before I give another star
