Highlights
Quality
With proper use of cutting fluid, these have worked well and retained their sharpness.
Good quality bits for times when i need a metric hole for clearance or tap sizes.
I was surprised that after repeated use they still produce larger metal shavings and drill right through that steel.
And the storage case is very rugged thick plastic.
Price
This set is a great value for your money .
Amazing set of bits for the price.
Overall, a good value for the price.
For the cost, these are handy to have around the shop for that occasion when you just need to tap a metric thread.
Shipping

They arrived in a very timely manner.
Competitiveness
It is impossible to find metric sized drill bit sets in the us, and this set is perfect for what i have in mind.
