Hi All,

I'm planning to take an EDM drill machine, since I find it difficult to drill holes in steels at hardness 40 - 45 HRC and the hole size is of the order 2-3 mm.

Could anyone here with hands on experience at the machine help me in what features should i be testing the machine for, other than proving my required components.

It uses a brass tube as electrode and the electrode has a wear of 20%
 
Hi, for starters look for a lot of technology in the database. look for the ability to read your wire programs so that you don't have to program 2 times. A separate filter system is nice to have also. Multiple guides, keyless chuck, DI bottle.
 
Usually EDM drilling with copper or bronze is at least a 100% wear situation. 20% wear is more typical of an aggressive copper/graphite electrode. A lot depends on settings but I would be tickled to get 20% wear on copper when drilling.
