Description This 10pc speed twist drill bits set are made of high speed steel. They feature a shank size of 1/16”, are a size #55, and have a diameter 1.3mm. Great for drilling ferrous metals, tough casting sand forgings, working hardened stainless steel and other hard steels and tough high tensile strength nonferrous metals like titanium
Shank Size 1/16”
I use these drill bits enough that, because of their small size (about 0.052", 1.32mm) I frequently need to replace one I haven't treated gently enough. These hold their edge well in non-ferrous metals, and last reasonably well. (I generally used them with a hand-held flex-shaft tool, but I'm sure they'd last longer with the stability of a good drill press behind them.)If you find yourself wanting holes that pass 16ga wire easily but snugly, this is the one to get. I'm happy with it.-- wiredweird
