AR400 steel and Drills
Posted: Wed Jan 23, 2013 7:17 pm
Anyone have any experience will AR400 steel?
I had never heard of it but from what I can find with Google, its used for wear plates and cutting edges. A friend of mine approached me with a possible job that would require a lot of drilling. The steel suppliers that carry it say that it can be machined with HSS, but from searching the web, most people claim it to be forged in Hell with an appetite for drills.
Any recommendations for drills? Material is 3/8" thick. I'm still waiting to hear back from him on the hole diam but its looking like either 1/2" or 3/4" holes. The job should between 50 and 80 holes so I'd like to avoid using the wrong drill and burning them up to fast.
Thanks,
Griz
