True 5% Cobalt Jobber Drill Bit Set, 10Pcs 2mm M35 High Speed Steel Twist Drill Bits, 118° Split Point Extremely Heat Resistant for Stainless Steel, Metal, Copper, Cast Iron, Wood, Plastic

Only used for a few days and tested most of them. A bit of chattering at high and medium high speed, but nothing too bad. They are quite aggressive and perfect for removing plenty of material from bad welds when doing welding sculptures. The finish will need going over with something smoother though, to get rid of the biting marks it leaves. Definitely wear a face shield and gloves and overalls would be a good idea. I had a t-shirt on and could feel bits of metal firing into my skin while using it. Nothing too bad but not the best idea.I used stone grinding wheels and sanding discs to smooth it over after as well as the diamond milling bits I have to mould everything into a smooth shape and get rid of the grinding look.

Good value small drill bits, nice product overall!

Nicely packed in a neat case. Have purchased before and they lasted well

they're very good

They are a very good buy, well worth the money.I have only had my set for a couple of days, but they have worked well on very hard plastic.You can see the plastic is being removed, as soon as you apply the grinding bit.Excellent purchase.

Ideal kit for drilling into tiles etc
