25 piece METRIC DRILL SET 1mm-13mm X 0.5mm increments

What I received was not from MSTC. Amazon made a mistake and lumped different sellers together under this listing. What I received did not come with the extras that at the time were advertised with it. When I complained to the seller (Not MSTC) she told me Amazon was incorrectly lumping her product with MTSC's, and she was having difficulty getting them to correct it (it finally was corrected). Although she went out of her way to provide me the missing item, it was the wrong item. I'm disappointed with Amazon on this one.The drill bits seem okay for my usage so I kept them.

Bits used and how: The 5mm, 6mm, and 7mm so far. I used a battery powered hand drill when drilling. When using these bits I didn't press hard and was careful not to catch or break them.Precision: I was hoping for a tight friction fit. Tight enough so that I would have to use a reamer to finish my holes, but I didn't. The tolerances are close enough to work and fit well. however, don't expect a fiction fit after drilling by hand. Perhaps if I used them in a drill press I could get a friction fit.Manufacturing: The color of the bits various from grey blue to a plum purple/brownish. Machining marks on the bits vary. They feel light.Overall: They work and got the job done for me. If I need more precision I will try them in a drill press. If that doesn't work I'll buy a more expensive bit.No huge complaints, cheap price (25 bits for 40$, slightly less than 2$ a bit), organized metal case (that's labeled for bit size), and the bits themselves are labeled. I imagine these will serve their purpose for the average DIYer.

I received this today an it is a true metric set unlike the other post that says its not.Maybe they didn't have the right equipment to really measure it accurately.The drill bit set I received is also made in USA. Yes, Made in the USA!I did not receive the screw identifier card they say they would include with the purchase,but for the price I'm not complaining. I can measure a screw with out it.

This the best metric drill set I have ever purchased and the price is a steal! I highly recommend it.

Some of the smaller bits (1, 2mm) came broken, but the folks at Bisco responded quickly to my inquiries and replaced the two broken pieces for me. Three stars for the product, but 5 stars for the service from Bisco.

Drill set was delivered promptly. It comes in a metal case that looks to be of the same quality as a standard drill case I have that is approximately 60 years old. As for the drill bits, only time will tell.

The package arrived in a timely manner as shown by the tracking. It was a gift for my son and he has used it and is very happy with it. Your listing for a metic index was a rarity because many of the large machine equipment suppliers didn't list them.KK

These are not true metric drills. They are not suitable for precision work that involves fitting metric machine parts. For example, the "5mm" drill actually measures 4.95 mm: a hole drilled with it will not go onto a true 5mm shaft.
