Ineffective Drill Bits for Professionals

As a result of using this product, I found that it broke so easily even at moderate pressure. These bits left rough and jagged edges on the metal making it hard to get a professional finish..

Pros
  • Unlikely to break in storage
Cons
  • Not efficient and reliable for industrial and scientific use.

Worst Drills Ever! Garbage!

So weak and fragile. I use 1/8" drill bits every day for work and have tried many brands over the years but I have never come across one as useless as this one. I promise you will be disappointed if you don't just use them on VERY soft material.

Pros
  • Power & Hand Tools
Cons
  • Available in Black only
