Useless Drill Bit Set for Industrial Work

This drill bit set is not worth the purchase for any serious industrial and scientific cutting needs. The bits are dull and cannot successfully complete any drilling tasks without causing damage to the surface material. The only pro of this product is that it comes with a case for easy storage. However, the cons heavily outweigh the pros as the quality of the bits falls short of any expectations for professional use.

Pros
  • Allows for drilling, deburring, and countersinking in one step, making it a time-saving tool.
Cons
  • Requires a steady hand and precise pressure to achieve accurate results, making it challenging for beginners to use.

Fragile enough not to be used.

The M5 bit snapped into the first hole in the pre-drilled 0.2 aluminum in 6061. Luckily I was able to remove the carcass and manually drill the remaining holes. Not impressed.

Pros
  • Power tool parts and accessories
Cons
  • Some bugs

Time Saver - Power & Hand Tools

For the price of the time saved just tell yourself I should have had this a long time ago! I use this for everything at work and saves time, the 2-1 drill/tap is good for setting screws in metal cases and more.

Pros
  • Tools & Household Items
Cons
  • Doubt
