    Jun 17, 2016 · I've looked into this a little, but I only really have basic tools, like a hand drill (mains powered), some cobalt drill bits, Molyslip metalworking compound, and a few other bits and pieces. For a start, I'm looking to drill and tap some M6 threads into the side of some 10mm Hardox.

    Jan 26, 2013 · AR400 isn't that bad to work with. I use HSS bits, good quality ones. Cobalt helps, but not necessary with 400. I don't think Harbor Freight bits would hold up well. I go a bit slower than A36, and KEEP IT COOL, and don't linger in the hole! If you star turnin' chips blue, it can harden up in a hurry.....hard enough you'll have to use carbide.
