10 Pcs High Speed Steel Cobalt Drill Bit Set 2 Pcs of Each 1mm(3/64"), 1.5mm(1/16") 2mm(5/64") 2.5mm(3/32") 3mm(1/8") Jobber Length Twist M35 Metal Drill Bit For Stainless Steel And Hard Metal

These appear to be metric drill bits, and are just similar to the English sizes. Even the 1 mm size held up to drilling into redwood, with being careful with the drill. The bits weren't as long as the ones I was replacing, but for the price I say 5 stars.

Worker well for drilling out stripped screws. Nice metal holder.

Decent for the price. They drilled holes. Not the best, but look at that priceThe smallest one, which was the one I really needed, does not fit in the chuck on my Milwaukee cordless drill. It's too small. Not really anything you can do about it, but I'm leaving this for other people.

Totally worthless.

Just started using them, but they seem to be a good value for the money. Sized correctly, priced well, but I cannot really offer much thought on durability as I'm going to use them on plastic for hobby work.

I have to half some of my stainless steels for certain projects, these drill the hole nicely without breaking.

These are absolute junk, I needed them to drill through the metal clips on ink pens. Right off the hit two broke, moved up to a bigger bit thinking it would be stronger…nope shattered into 3 pieces. I drilled slow with oil, broke. Drilled fast and broke, swear if the drill side eyes these bits they break.
