Superior Quality Drill Bit Set

The Extra Drill Aluminum Plastic set is a must-have for anyone in the cutting tool business. My analysis of this product showed that the set is incredibly durable and can withstand heavy usage. The bits have a sharp cutting surface, ensuring precision and accuracy with each use. However, the set only covers drill sizes from 4-10mm, which may limit its use for certain industrial applications.

Pros
  • Durable, sharp cutting surface
Cons
  • Limited drill size range

Drill burned out immediately

Tried to drill a 10mm hole but through a 1/8" steel plate. I didn't even pierce the other side until it was sooty. Also used coolant. Could be good for wood. Terrible for steel. Don't waste your money, just spend it on a good cobalt crown.

Pros
  • Stable test results
Cons
  • Could have chosen a newer model

Not the best parts I've bought

Not the best parts I've bought. I only used a 1/8" bit, it didn't feel too sharp and started to bend when I pushed it a little. I don't use long bits very often so I think they do what I need. I want them to only finish when the normal drill bit stops just before the hole is finished.

Pros
  • Great construction
Cons
  • Crumpled packaging
