Shelbyville Posted January 16, 2013 Report Share Posted January 16, 2013 So here's the deal - I finally broke enough of the bits in my 29 pc drill bit set to warrant just buying a new set instead of a bunch of individual bits. I go down to the local hardware store and grab another set just like the one I've got and take it back to the shop. I open it up and start reading the card that came with it and it says these bits are for wood, plastic & SOFT metal (Cu, Al, brass, etc). These bits are HSS (high speed steel). Since when is HSS not good enough for drilling steel? Is it because everything now comes from China? I have used HSS bits for steel for decades and always got along just fine as long as the bits are kept sharp and a reasonable feed speed is used. Do you have to buy cobalt bits now to be able to do what you used to do with HSS? Quote Link to comment Share on other sites More sharing options...
