12:20 PM rue_mohr: sorta
12:20 PM Tom_L: or use lotsa lube on the flat ones
12:20 PM rue_mohr: my price limit is somewhere around $30
12:21 PM rue_mohr: they grind in the taper when setting it up
12:21 PM rue_mohr: I found a listing with one in use
12:21 PM rue_mohr: they shaped up the end
12:21 PM rue_mohr: I just like to cut too deep
12:21 PM rue_mohr: thats how I shattered the one I had
12:21 PM Tom_L: cut a small relief on the part you're not keeping then
12:22 PM Tom_L: as you go in
12:22 PM Tom_L: basically 2 cutoff passes
12:22 PM rue_mohr: aha, a listing for one for $20
12:22 PM Tom_L: doesn't need to be much
12:22 PM rue_mohr: hmm
12:23 PM rue_mohr: wow, the internet is slow when I'm usually at work
12:24 PM rue_mohr: 8% cobalt is cheaper then HSS?
12:25 PM rue_mohr: is the 8% added to mild steel?
12:25 PM Tom_L: if you say so
12:25 PM Tom_L: i've no idea
12:25 PM rue_mohr: oh haha, aliexpress doesn't work in my old browser, right
12:26 PM rue_mohr: OMG
12:26 PM rue_mohr: it just occured to me that I can cut up circular saw blades for cut-off tools
12:26 PM rue_mohr: carbide...
12:26 PM Tom_L: you could get a few from one
12:26 PM rue_mohr: it works if you have a cheap source of blades ;]
12:27 PM Tom_L: make sure the point is ground the right direction
12:27 PM Tom_L: every other one usually
12:27 PM rue_mohr: cut the blade back to make the holding arm in the right direction
12:27 PM rue_mohr: oh, you would have to be a cross cut... I think
12:27 PM Tom_L: the carbide tip
12:28 PM rue_mohr: I have a diamond disc too
12:28 PM Tom_L: those don't do as well as an abrasive cutoff wheel
12:28 PM rue_mohr: but ok, amazon

12:28 PM Tom_L: i have both
12:29 PM Tom_L: a green stone is what you use for a carbide grind wheel
