### ⭐ Poor quality drill bit made with inferior steel and hardened poorly.
*by S***U on 13 October 2019*

Very poor quality made items made with inferior steel. I also doubt the hardening & tempering if the steel. I was using this to drill out a block of olive wood to make a knife handle and the steel twisted and did not snap and when the drill was reversed to pull out the 8mm drill bit it actually unwound it’s self and snapped at the shank and left the remaining unwound drill but stuck in the wood ruining a £25.00 block of olive wood burl. My faith in these drill bits and in Nielsen has been shaken to the point of me considering no longer purchasing there goods. If Nielsen cared about there customers they would get in touch with me to rectify this issue but I don’t think they would as they would not of sold me a inferior quality tool compared to it competitors and it’s almost a guarantee if a company sold you a poor quality product then they don’t care for there customer. I suppose if they get thousands of reviews then they probably won’t read this and therefore won’t right this wrong as you can’t right a wrong with an other wrong. I’ve left a picture of the shank to show you where it twisted then snapped. It’s my theory that they are only hardening the shaft up to the base of the shank which is where it twisted and the bit un wound it’s self to be straight which ruined my unique piece of olive wood burl and the weak point is the transition from the annealed soft steel to the point of the hardened steel which is exactly where it twisted and snapped so it’s self evident that I’m probably right.
