I have kinda had it with the locally available bits and abrasives. Doing a lot of drilling in hot rolled steel, and am slated to have to do tons more. There has got to be something better than the Irwin brand cobalt bits for this.
Found this site: http://www.wintersdrillbitcity.com/ It does not have a much info in the way of prices, etc. Rather old school. Anyone have any experience with these guys? Or any suggestions? I am so done buying drill sets, and would just like to buy the bits I tend to use by the dozen or more. Also, been doing some finishing on steel flat bar that needs to be glass smooth. Been having good results with a belt sander running the black gator brand belts, but like the drill bits, wonder if there might be something better. Fabricators, chime in! |

Get yourself a Drill Doctor too. You can resharpen cobalt bits. But, HSS and Titanium bits are coated, so resharpening doesn't work since the metal inside isn't hardened.
I've gotten in the habit of sharpening a but every time the cutting starts to slow. You can sharped them in under 1min and they work like new. |
