13Pack HSS Twist Drill Bit Set Metric M35 Cobalt Steel High Speed Steel Titanium Coated Drill Bit Tool Extremely Heat Resistant with Straight Shank 1.5mm-6.5mm for Drilling Tool Wood, Metal & Plastic

This neat drill bit set has exceeded my expectations, for the low cost these have performed really well and have been used on many different materials (wood, stainless steel and iron), they come in every size that you will need for home diy, will definitely be buying these again.

Go through brick easily, sizing accurate, struggle with concrete

Fine, but, on stainless and hardened steel, expect some breakages with the smaller bits and expect that it will take around 15 minutes per mm to drill (if holding the drill by hand and not a press). I also found that they blunted after a while, and then, of course, it takes even longer, extending the time even before you get to the end of the first hole. I broke two bits and sent one completely blunt drilling one hole in a stainless bolt. This is likely my issue do to the choice of bit for the application, as carbide bits would have been a smarter choice. I have now rectified that, and will keep these remaining bits for other, less hard metal, applications.

Very strong drill bits

Drills ok case rubbish, broke second time around.

Only used once to date but they seem.to be robust and well made

These are the best. I spent an hour yesterday trying to drill a piece of metal, starting (or not starting with a 3mm bit. I started with 4mm today and it went straight through - 2 more drillings and up to 7.5mm - 2 minute job.Pilot hole drilled I was soon stepping up to 12mm - incredible sharpness and worth every penny.

Good quality handy little set
